Tec-Sem founded in 1981 by Jakob Blattner in Switzerland is one of the pioneers in clean room automation. Over the past 30 years, Tec-SemGroup AG has established itself as a leader in semiconductor equipment manufacturing as well as in semiconductor OEM-automation solution provider. Tec-Sem Group AG is specialized in semiconductor equipment development and manufacturing with a focus on Wafer and Reticle Management solutions.

Tec-Sem’s proprietary technology used in wafer- and reticle- (photo-masks) stockers, which are sold directly to semiconductor manufacturers, is characterized by an ultra-dense, highly cost-effective storage methodology in which wafers and reticles are stored "bare" rather than in carriers, making Tec-Sem the leading supplier of these systems worldwide. Tec-Sem’ tool OEM solutions focus primarily on batch handling and tool buffer requirements of high-throughput process tools like wet benches and furnaces. Tec-Sem’s installed base of wafer and reticle management systems are increasing the efficiency and throughput in several our semiconductor fabs around the world. Tool buffers and batch handling systems are also installed in several dozen 200mm & 300mm tools. The company is ISO9001 certified.
