Jireh Semiconductor, Inc., a wholly owned subsidiary of Alpha and Omega Semiconductor Ltd., is the in-house wafer fab for AOS and is located in Hillsboro, Oregon. Innovation and technology have always been the philosophy of AOS since its inception. AOS’ acquired an 8-inch wafer factory located in Oregon from Integrated Device Technology (IDT) to help AOS to speed up the development of innovative Power Device technologies. The new in-house wafer fab, now known as Jireh Semiconductor, Inc., allows the company to grow revenue faster by expanding into new applications and markets and has also become a key R&D center for the business. As a result of this acquisition, the company has transitioned from its original Fabless model to a Fablite model which will enhance its ability to respond quicker to customers’ needs for innovative products to further strengthen its partnerships with strategic customers.

Jireh, with the full backing of AOS, is dedicated to the mission of bringing manufacturing back to the USA profitably and currently supports a staff of over 500 employees, with even more growth on the horizon.
