Silicon on Sapphire (SOS)

 

 

Silicon on sapphire (SOS) is a hetero-epitaxial process wherein a thin layer of silicon is 'grown” on a sapphire (Al2O3) wafer. SOS is part of the silicon on insulator (SOI) family of CMOS technologies. Silicon on sapphire is primarily used in military and space applications because of its inherent resistance to radiation. It has seen little commercial use to date because of difficulties in fabricating the very small transistors used in modern high-density applications. Problematically, the SOS process often results in the formation of dislocations from crystal lattice disparities between the sapphire and silicon. This leads to unusable wafers and drives up the production cost.

Products & Services
Memory chips are internal storage areas in computers. Although the term “memory chip” commonly refers to a computer's random access memory (RAM), this product area includes many different types of electronic data storage. Computer memory stores data electronically in cells. Without memory chips, a computer could not read programs or retain data. Search by Specification | Learn more about Memory Chips
Complex programmable logic devices (CPLDs) are integrated circuits (ICs) or chips that application designers configure to implement digital hardware such as mobile phones. CPLDs can handle significantly larger designs than simple programmable logic devices (SPLDs), but provide less logic than field programmable gate arrays (FPGAs).

Dynamic random access memory (DRAM) chips are single-transistor memory cells that use small capacitors to store each bit of memory in an addressable format that consists of rows and columns. Because capacitors are unable to hold a charge indefinitely, DRAM memory chips require a near-constant pulse of current to retain stored information.

Erasable programmable read-only memory (EPROM) chips are programmable, reusable computer chips that can be erased using ultraviolet light and reprogrammed with a PROM programmer or PROM burner. Search by Specification | Learn more about EPROM
Electrically erasable programmable read-only memory (EEPROM) chips are similar to PROM devices, but require only electricity to be erased. Search by Specification | Learn more about EEPROM
