A complete chain from wafer to shipment
Chip design, wafer fabrication, packaging and test, and application engineering under one roof.
TDSEMIC was founded in 2011 and focuses on the production and sales of integrated circuits. We operate as a brand manufacturer and authorized distributor, representing more than 30 domestic brands. In 2010 we established a packaging & test foundry and alloy-wire material plant in Suining, Sichuan, and a wafer design house in Chengdu the same year — covering design, wafer, packaging, test and solution development end to end.
Every part ships with full electrical characterisation, RoHS compliance and traceable lot information. Engineering samples and datasheets are available on request.
