We also offer process transfer services to IDMs that wish to use their own technologies and processes. Our process transfer services are also used by fabless companies with proprietary process flows that wish to have an additional supplier for purposes of geographic diversity or for the manufacture of an advanced technology node that is very costly to build themselves. Our process transfer services include development, transfer, and extensive optimization as defined by customer needs. 
 
With our world-class engineering team, well established foundry process methodologies and vast experience, we offer state of the art factories for core bulk CMOS and specialized technologies such as RF SOI, silicon photonics, SiGe and MEMS, among others.
 

We are a trusted, customer-oriented service provider that has built a solid reputation in the foundry industry over more than thirty years. We have built strong relationships with customers. Our consistent focus on providing high-quality, value-added services, including engineering and design support, has allowed us to attract customers that seek to work with a proven provider of foundry solutions. Our emphasis on working closely with customers and accelerating the time-to-market and performance of their next-generation products has enabled us to maintain a high customer retention rate, while increasing the number of new customers and new products.
 
We continuously aim to expand our capacity and capacity flexibility among our different technologies.  To accomplish this, we invest in our facilities and acquire external capacity (such as Fab 10 and Fab 11 under the capacity corridor agreement with Intel) or through fab acquisitions, as we have done in the past, independently or through third-party collaboration and/or funding (including cash, equity or in-kind investment). We also offer from time to time a wide range of support services for the establishment of new semiconductor fabrication facilities or the ramp up of existing facilities owned by third parties, using our technological, operational and integration expertise, for which we receive payments based on the achievement of pre-defined milestones and may also be entitled to certain capacity allocation and other rights, all subject to definitive agreements underlying such projects.
 
We derived a significant amount of our revenues for the year ended December 31, 2024 from our target specialized technologies: RF CMOS, including RF SOI (RF CMOS on silicon-on-insulator), SiGe BiCMOS, silicon photonics, power ICs, discrete devices and CMOS image sensors. We are highly experienced in these technologies, having been an early entrant and having developed unique proprietary technologies, including through licensing and joint development efforts with our customers and other technology companies.
