 products using larger geometry process technology
at a lower cost while achieving similar or superior performance to that achieved using a smaller geometry standard RF CMOS process technology.
In addition, our SiGe technology supports high voltages not available in very advanced CMOS technology nodes. We have developed enhanced
tool capabilities in collaboration with large semiconductor tool suppliers to achieve high-yield SiGe volumes. We believe this equipment
and related process expertise position us as one of the few companies with demonstrated ability to deliver SiGe BiCMOS products. We currently
have 0.35 micron, 0.18 micron and 0.13 micron SiGe BiCMOS technologies available in mass production and are adding a 65nm SiGe BiCMOS
platform for our customers’ most advanced next-generation products.

Silicon Photonics (SiPho)

Our industry-leading silicon photonics platform targets AI, data
center communications and other optical applications. The SiPho process complements our SiGe BiCMOS processes by offering a companion
solution that integrates optical components in the expanding data communication market. This platform enables the integration of photodetectors,
optical modulators, and other optical components, which were previously assembled in optical modules as discrete components and can now
be integrated into a single die potentially lowering cost, reducing footprint and improving performance of advanced optical transceivers.
We currently have a high-volume, production 200mm platform (PH18) that has benefited from AI-driven growth in optical interconnects, making
it a leading SiPho platform in the 400Gb/s to 800Gb/s market. We have begun production of next-generation products targeting 1.6Tb/s and
are developing and prototyping various advanced technologies aiming at 3.2T/s, as well as co-packaged optics (CPO) and integrated laser
applications for the future. Additionally, we have recently released design kits for a 300mm version of our SiPho platform, which offers
performance advantages and additional capacity.

RF CMOS

Many RF products today are built using RF CMOS technology on silicon-on-insulator
(SOI) substrates (RFSOI). These RFSOI process technologies include devices optimized to deliver higher performance and improved isolation
compared to those in bulk RFCMOS processes. We currently utilize RFSOI process technologies at 0.18 micron, 0.13 micron and 65 nanometer
lithography nodes to fabricate various devices, including antenna switches with
