Wafers and chips are vital to the health of STATS ChipPAC. The company assembles and tests integrated circuits (ICs) for semiconductor manufacturers on a contract basis. STATS ChipPAC receives wafers of ICs from manufacturers that it inspects for flaws, sorts, and cuts into individual chips. It then assembles, packages, and tests them. Analog Devices, Broadcom, Freescale Semiconductor, Intel, Marvell Technology, and QUALCOMM are among the company's top customers. About three-quarters of the company's sales come from the US, where many of the industry's fabless semiconductor companies are based. Singapore Technologies (which is owned by the Singapore government) owns 84% of STATS ChipPAC.
