FORMOSA MICROSEMI CO. LTD was founded on July 1996. The original founder and chairman of the board, madam Irene Yang , worked at quality control department of an American company -General Semiconductor Co. in 1970s. When production of rectifying diodes is gradually transferred to Mainland China, only products with higher added values can survive in Taiwan. Therefore presently, Schottky barrier diodes (which have lower leaking current, larger efficiency with the highest unit price among all the rectifying diodes; in the times asking speed, a tendency that Schottky barrier diodes gradually replaces traditional diodes has been forming.) presently have three production modes including those of 1 ampere, 3 ampere and 5 ampere. The planning of productivity includes the mini mode 1 ampere for 1KK, and the modes 1 ampere for 6KK and 3 ampere for 2KK in production operations of welding and shaping, the rest is finished by contractor’s processing. At present, our most and chief clients are domestic OEMs of semiconductors and brokers for electric parts’ traders. We sell a small number of them under our own brand to domestic clients. In view that the electronic parts are developing towards the modes being light, thin, short and small, various surface adhesion diodes will be the main products in the future.
