CS international 2019

Building on the success of its predecessors, the ninth Compound Semiconductor International Conference pinpointed the most promising opportunities for this industry.

Richard Stevenson, CS International Conference Programme Manager and CS Magazine Editor reflects on the March 2019 event.

A great conference has to excel on many fronts. It has to feature a wide range of engaging presentations from leading companies, helping delegates to identify the most important markets for tomorrow; it has to attract a good number of attendees that network, sharing their insight; and has to include many exhibitors, offering opportunities to improve productivity.

Judged in these terms, this year's Compound Semiconductor International Conference was a tremendous success. No-one there could have failed to identify what is now the most promising market for this sector - the electric vehicle industry - while attendance and exhibition numbers hit all-time highs, with 700 delegates coming to Brussels for this meeting, plus the co-located Photonics Integrated Circuits International and Sensors Solutions International. Sponsorship across the three conferences, held over 26-27 March, totalled 70.

Increasing the blocking voltage of GaN HEMTs

GaN-based switches will offer greater efficiency, power handling, and compactness compared with the well-established, widely available silicon MOSFET power devices—all factors that are critical to meeting the needs of today’s systems. However, the vertical breakdown voltage of GaN-on-silicon heterostructures is currently limited to slightly above 1000 V, preventing this technology from benefiting higher voltage applications. This talk will discuss some potential solutions for next-generation, lateral GaN-on-silicon power devices targeting 1200 V and above. This would pave the way to a much lower on-resistance than other existing technologies operating above 1 kV.

Printing GaN HEMTs onto silicon CMOS

Integration of GaN high voltage transistors into Silicon CMOS could combine superior electrical parameters of GaN HEMTs and the huge logic functionality of Silicon CMOS. Several issues of a monolithic integration of GaN devices into CMOS like material mismatch and thermal budgets can be overcome by heterogeneous integration by micro-Transfer-Printing. This process includes a release etching of the GaN on silicon HEMT devices, mechanical printing of many devices in parallel followed by on-wafer metal wiring. Challenges like thermal heat removal and the required low resistive metallization have to be addressed. Results of printing experiments with small GaN HEMTs on Silicon CMOS will be presented.

Inspection Convergence: Photoluminescence Imaging and AI

The last several years have seen the rapid adoption of new technologies that converge super-resolution optical microscopy and AI analysis.  Combined with AI, Photoluminescence Imaging enables quantification and categorization of defects that conventional Brightfield microscopy overlooks. Photoluminescence enables the characterization of stacks and folds in SiC that cannot be seen by other methods as quickly. Using diffused light at the wavelength of the material bandgap, it not only provides a precise measurement, but one that scales faster than any laser-based method. PL imaging provides a way to test functionality on the same wafer or product, and potentially at the same time as routine classification, giving a robust single station for solving production problems and leading to faster design iteration.

Presentation

Direct wafer bonding for GaN devices

GaN based devices are emerging rapidly due to the advantageous material properties of very high breakdown voltages, high electron mobility and saturation velocity of GaN. This makes GaN ideally suited for high power electronics, RF transistors and optoelectronic devices. However, GaN typically has to be combined with other materials to achieve high performance on an economically viable level. Direct wafer bonding is a versatile technique to join two similar or dissimilar materials without restriction by crystallographic structure or orientation. It minimizes also the influence of lattice and thermal mismatch. As a result this manufacturing technology enables new integration schemes for combining GaN with various substrate materials. It offers a high flexibility by imposing strict quality requirements without impacting the crystal structure.

Pushing Performance in RF for 5G Networks

We are at the intersection of GaN and mmWave with AESA radar, MIMO and now, 5G, which are all driving to higher volume production. Interestingly, the GaN technology that matured under an industry-government partnership model is now a market shaper for commercial 5G networks. 5G is all about increased capacity, lower latency and increased robustness, which is supported by higher bandwidth and higher frequencies, making it a natural fit for leveraging the capabilities of GaN-on-SiC and mmWave technologies. 5G is ramping, but there are still unknowns and the right technology needs to be deployed for the right customer needs. Size, efficiency and power will drive the solution. The greater the efficiency, the higher the transmitted power or the lower the operational costs that will make 5G networks a reality.

Fabless PICs in InP: Why, What, and How?

As PICs in InP are gaining momentum, their areas of application multiply and end users move up in a food chain. PICs are becoming customized, while their development goes beyond the means of the users. Fabless model is emerging as a solution, but its advancement depends on whether it meets the needs for customization and scalability. The regrowth-free taper-assisted vertical integration (TAVI) is a versatile technology that allows to decouple epitaxial growth and wafer fabrication, such that continuous development into production of fully custom InP PICs is achievable by outsourcing both to industrial-grade foundries. Referring to the TAVI technology, the talk will review the status and prospects of the fabless PICs in InP.

GaN-on-SiC Technologies for 5G Radio Access

Initial build-out of the 5G radio access network has commenced with sub-6GHz and mmWave infrastructure leveraging beamforming and MIMO architectures. These active antenna systems employ multiple RF chains, and a 5G modulation scheme requiring transmit power amplifiers operate at 10dB peak to average power ratio. This condition places a premium on Tx PA efficiency in back off, and the choice of semiconductor technology has a direct impact on access point coverage and operating costs. Gallium Nitride has achieved impressive levels of power performance, and is viewed as a viable PA technology for high EIRP scenarios. To satisfy the cost and performance objectives in this highly competitive market, WIN Semiconductors has commercialized GaN-on-SiC technologies to address both the sub-6GHz and mmWave bands.

Antimonide LEDs for gas sensing

Unlike visible to near-infrared light, mid-infrared (mid-IR) light has attracted much less attention within the compound semiconductor community, due to limited commercial applications. However, the situation is changing. Following the recent concern surrounding global warming, technologies for monitoring and reducing greenhouse gases, such as carbon dioxide (CO2) and methane (CH4), are attracting a lot of attention. Among them, gas sensing technology based on mid-IR light absorption can take an important role. Antimonide LEDs and sensors, which have a narrow-bandgap and work in the mid-IR region, are ideal light sources and detectors for such application. In this presentation, recent progress in antimonide devices will be reported.

Accelerating Photonics Growth through Advances in High Performance As/P MOCVD and Wet Processing Technology

Photonics devices based on Arsenic/Phosphide (As/P) materials such as VCSELs and EE lasers are seeing high demand in 3D sensing, LiDAR, data communication, infrared illumination and fiber pumping. Double-digit growth over the next five years is expected as existing applications proliferate and new applications become available [1]. Manufacturers of photonics devices rely on Metal Organic Chemical Vapor Deposition (MOCVD), Lithography, and Wet Processing technology and equipment for their device production needs. As the critical first step in device manufacturing, MOCVD epitaxial growth technology must lead the way to meet growing customer demand for tighter performance requirements by improving compositional uniformity and dopant control while reducing cost-per-wafer via higher productivity, best-in-class yields and lower operating expenses. For epitaxy growth in VCSELs, key parameters are excellent within-wafer, wafer-to-wafer and run-to-run thickness uniformity of the DBR and MQW layers as well as the Fabry-Perot cavity dip uniformity. Equally important for VCSELs are the compositional and doping uniformity as well as background carbon and oxygen levels. The epitaxy films must also have very low defectivity. The above also holds true for EE lasers, except they do not include DBR layers. This presentation will use data to demonstrate how device manufacturers can use a new As/P MOCVD platform to achieve excellent uniformity and repeatability over long campaigns. Wet Processing is also critical for these photonics applications as the epitaxy layers must be patterned in the production process. Patterning is done using wet etch and metal lift off (MLO). Critical parameters for wet etch include etch uniformity and endpoint detection. Highly uniform film layers enable superior device performance and yield. In addition, a production-proven solvent-based process for MLO and photoresist strip steps is required to create the pad layers. This presentation will also show how immersion followed by spray enables complete removal for difficult to remove resists at high throughput.

Mastering the manufacture of microLEDs on silicon

For micro LED displays, monolithic integration of arrays is a preferable approach to producing high-resolution displays, because it can directly transfer a processed LED wafer to a target backplane through wafer-bonding technology. For this approach, production ideally involves the use of large, flat epi-wafers with a narrow wavelength bin range and a low defect level. These characteristics are critical to improve the final yield. GaN-on-silicon technology offers tremendous potential to address these epitaxy requirements over incumbent sapphire technology. Our recent progress on the growth of GaN-on-silicon epiwafer for micro LED displays will also be discussed

The Fabrication of High Quality Low Cost Free-standing GaN Substrates and GaN Templates

Bulk GaN substrate has many advantages such as low dislocation density, high heat dissipation rate as well as no lattice mismatch and thermal mismatch for its homoepitaxial characteristics in applications like short wavelength light-emitting diodes, blue or green light laser diodes, high power electronics and microwave devices compared to their foreign substrates. By introducing two new technologies-the substrate separation and acid wet aching, high quality 2-inch bulk GaN wafer with dislocation density of 5×105 cm-2 was obtained by HVPE homoepitaxy. The result showed that the FWHM of the (002) and (102) rocking curves achieved .

39.9 arcsec and 47.5 arcsec respectively, indicating their high degree of crystalline quality. Furthermore, the roughness of the final wafer is 0.11nm and the total thickness variation is below 15um. Also, we launched 4-inch free-standing GaN substrates with dislocation density below 5×106cm-2 at the beginning of this year. We have developed a large-scale HVPE system which can produce 21 2-inch wafers per run and substantially reduced the production cost. It is the largest reported HVPE system all over the world. In order to settle the problem of thickness uniformity、growth rate and surface defect, we simulated the flow field of the HVPE system with different reactor and equipment structure using SolidWorks and Fluent. By modifying the reactor and furnace structure, now we succeed to produced 21 wafers of 2-inch with good thickness uniformity and smooth surface. And the growth rate has achieved 100um/h.

III/V Nano-ridge Engineering for novel Device Integration on Si

Meeting the high requirements of cost-efficiency and scalability in III/V integration on Si, the monolithic hetero-epitaxial growth is the most promising approach although facing the challenges of misfit defect formation due to the large lattice mismatch. Selective area growth of III/Vs in narrow trenches is a well-known method to achieve a high crystal quality. The pronounced growth out of trenches in line with an engineered nano-ridge shape is a unique integration approach introduced by imec. It leads to an enlarged III/V nano-ridge volume for novel device architectures. In this presentation I will explain this unique III/V nano-ridge engineering approach and evaluate the challenges and opportunities in epitaxial growth and new device design.

Presentation

Laser-lift-off (LLO) and CONDOx for wafer ultra-thinning process for 3D stacked devices, TSV, eWLB and WLCSP wafers

Wafer ultra-thinning is essential for advanced 3D packaging, at the same time challenging. The final thickness of the substrate is very small and the bumps may be higher than the substrate thickness for 2,5D interconnects. At DISCO, we deal with the extreme thinness of wafers and have developed solutions to make thinning processes as efficient as possible, to protect the product and to allow for easier handling of TSV, eWLB and WLCSP wafers.

Extreme thin grinding is a key component of 3D stacked devices interconnected by TSVs and advanced semiconductor scaling. For some products, the final thickness of the silicon is up to 10 μm or even smaller. Yet, at a certain thickness, wafers lose their rigidity and tend to warp or break easily. Temporary bonding is a countermeasure where a glass carrier is bonded temporarily to the wafer. However, the main issue is to release the wafer from the glass carrier after thinning down the silicon without wafer breakage or high tension.

A laser-supported release (Laser-Lift-Off) has been developed by DISCO which has several advantages towards other release techniques like chemical or thermal release. In the presentation, we will discuss the latest updates of Laser Lift-Off in wafer-on-wafer (WOW) technology and which benefits come with our optimized technologies.

Further, we will introduce our latest solutions for thinning eWLB or WLCSP wafers with high bumps. We will give examples how DISCO’s CONDOx technology allows for thinning wafers with final Si thickness of 25 μm and 200 μm bump height without residues, edge chipping and a further improved total thickness variation (TTV).

Enabling Global Mega Trends with Compound Semiconductors

Compound Semiconductor materials are accelerating their penetration in both industrial and consumer products at a rapid pace. While the first area is mainly driven by performance enhancements or savings at operational levels, increased adoption into consumer products can only be enabled if both the provision of additional, innovative benefits for the end customers and cost control at parity to existing solutions are met. This holds true for laser devices, for which performance, yield and cost control, enabled by planetary reactor technology, have achieved penetration of VCSELs (Vertical Cavity Surface Emitting Lasers) and EELs (Edge Emitting Lasers) to broader consumer markets. Our presentation will review the business opportunity for compound semiconductor advanced applications ranging from micro LEDs to 3D sensors, as well as Power and RF devices.
