 incorporate higher density passive components, such as capacitors and resistors, as well as improved active components, such as native or low threshold voltage devices, and improved isolation techniques, into standard analog CMOS process technologies.
 
In recent years, silicon has also been used to control optical signals in silicon-photonics (SiPho) technology. This technology reduces the cost of assembling optical transceivers, which convert optical signals to electrical signals and vice versa, by providing a platform that integrates multiple functions on a single chip instead of requiring multiple discrete components. Such technology utilizes much of the same semiconductor equipment used to manufacture CMOS, benefiting from the extensive installed base and manufacturing efficiency.
 
The enormous costs associated with modern fabs, combined with the increasing demand for complex products, have created an expanding market for outsourced foundry process manufacturing services. Foundries can cost-effectively supply advanced process technology services to even the smallest fabless companies by creating economies of scale through pooling the demand of numerous customers. In addition, customers whose IC designs require process technologies other than standard digital CMOS have created a market for independent foundries that focus on providing specialized process technologies. Specialty process technologies enable greater analog content and can reduce the die size of an analog or mixed-signal semiconductor, thereby increasing the number of dice on each wafer and reducing final die cost. In addition, specialty process technologies can enable increased performance, superior noise reduction and improved power efficiency of analog and mixed-signal semiconductors compared to traditional standard CMOS processes. These specialty process technologies include advanced silicon photonics technologies, analog CMOS, specialized RF devices on SOI, radio frequency CMOS (RF CMOS), CMOS image sensors (CIS), non- imaging sensors of different types, high voltage CMOS, bipolar CMOS (BiCMOS), silicon germanium BiCMOS (SiGe BiCMOS), bipolar CMOS double-diffused metal oxide semiconductor (BCD), silicon photonics platforms, NVM technologies and special devices for AI technologies. Due to our extensive and diversified work in specialized process technologies, we have the required skills to provide quality and flexibility in this technology intensive environment which is rapidly changing. We work closely with our customers to provide them with unique and specialized solutions needed for their business success.
