CMOS for RF and High-Performance Analog
 
Our SiGe BiCMOS process technologies offer more features than RF CMOS or standard BiCMOS processes and are well suited for advanced RF and high-performance analog semiconductors, such as high-speed, low-noise front-end wireless components, optical and copper-wired networking components, automotive radar components, hard-disk drive pre-amplifiers, power amplifiers, and low-noise amplifiers. These technologies generally incorporate silicon germanium bipolar transistors, which are formed by depositing a thin layer of silicon germanium within a CMOS process, to achieve higher speed, lower noise, and more efficient power performance than regular CMOS process technology. SiGe BiCMOS can achieve speeds equivalent to those demonstrated in standard RF CMOS processes that are two process generations smaller in line width. For example, a 0.18 micron SiGe BiCMOS process can achieve speeds comparable to a 90 nanometer RF CMOS process. This allows for the creation of analog 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
