USJC provides Contract manufactuaring servise of Semiconductor as a member of UMC in Taiwan (the world's second largest foundry).
We have one of the largest 12 inch Logic LSI plant in Japan and produce about 35,000 wafers/month.
We implements proactive disaster mitigation measures, including the installation of earthquake-resistant structures, establishment of Li-capacity backup power supply, and deployment of LNG satellite bases.
USJC offers a range of services that cover everything from design support to manufacturing. Our customers benefit from our extensive 40 years of experiences, allowing us to provide speedy and efficient solutions to meet their needs.
Our foundry information service, MyUSJC, provides customers with access to our design technology offerings, customer product information, and measurement results.
The shuttle service is a prototype service using a Multi Project Wafer (MPW). By allowing several customers to share masks and wafers, chip prototyping can be completed at a reduced cost.
Together with our customers, USJC aims to contribute towards the realization of a smart society through the technologies and services we provide. Our advanced technology and support allow us to produce products that support the development of a smarter society.
Surrounded by an abundance of water and rich natural environment, the Mie Plant aims to be an advanced semiconductor manufacturing fab that maintains harmony with the natural environment.
Mie Plant certified to Environment Management System(EMS) "ISO14001"
USJC sales team is available to assist customers in Japan with accessing UMC Group's fab capacities and technology.
