Since 1977, we have been developing custom IC mainly Analog semiconductor used for Audio/Video for over 40Years. We are the experts in photo ICs and analog ICs and have developed more than 200 photo ICs for laser disk,CD/DVD/BD pickups, and more than 300 products including other analog ICs. Most of them are custom ICs that our engineers have developed to meet the needs of our customers (consumer electronics, industrial equipment, and in-vehicle devices), and we offer an "analog IC turnkey service" by taking advantage of our in-house FAB production.

Please feel free to contact us from "Contact us" if you have any questions about custom IC development (analog IC turnkey service)."
