FormFactor designs, develops, manufactures, sells, and supports advanced semiconductor probe card products. Probe cards are used to perform wafer tests--in other words, the testing of the semiconductor die, or chips, while the die are still constituted on the semiconductor wafer. Wafer tests enable semiconductor manufacturers to determine whether die will meet specifications and be saleable. FormFactor customizes its probe cards for its customers' unique wafer and chip design, by modifying and adapting their product architectures to meet design layouts. Customers for the company include semiconductor chip manufacturers in the DRAM, Flash, and SoC markets.
