Pericom Semiconductor Corporation company was founded in 1990 and is headquartered in San Jose, California. Pericom Semiconductor Corporation (Pericom) designs, develops and markets integrated circuits (ICs) and frequency control products (FCPs) used in the electronic systems. The IC products include functions, which support the connectivity, timing and signal conditioning of parallel and serial protocols that transfer data among a system's microprocessor, memory and various peripherals, such as displays and monitors, and between interconnected systems. The FCPs are electronic components, which provide frequency references, such as crystals and oscillators for computer, communication, and consumer electronic products. The Company’s subsidiaries include Pericom Semiconductor (HK) Limited, Pericom Taiwan Limited Corporation (PTL), Pericom Asia Limited (PAL) and SaRonix-eCERA Corporation (SRe). On October 27, 2008, the Company purchased the remaining 12.1% interest in PTL.

Photronics, Inc. was founded in 1969 and is headquartered in Brookfield, Connecticut. Photronics, Inc. (Photronics) is a manufacturer of photomasks, which are high precision photographic quartz plates containing microscopic images of electronic circuits. Photomasks are a key element in the manufacture of semiconductors and flat panel displays (FPDs), and are used as masters to transfer circuit patterns onto semiconductor wafers and flat panel substrates during the fabrication of integrated circuits (ICs) and a range of FPDs and, to a lesser extent, other types of electrical and optical components. The Company operates principally from nine manufacturing facilities, two of which are located in the Europe, two in Taiwan, one each in Korea and Singapore and three in the United States. During the fiscal year ended November 1, 2009 (fiscal 2009), Photronics closed its manufacturing facilities in Manchester, United Kingdom and Shanghai, China.
