Toppan Enters Power Semiconductor Business

Toppan has from April, 2023 launched a contract manufacturing handling service for power semiconductors.

It can be challenging to secure wafer manufacturing capacity for power semiconductors for in-vehicle applications, industrial devices, and factory automation in particular. Focusing on those needs, Toppan will perform porting and manufacture for the wafer processes of device manufacturers. Based on a collaboration agreement, the manufacturing process itself will be established at the Niigata plant of JS Foundry K.K. (JS Foundry).

The service will enable device manufacturers to respond to strong demand for mass production of power semiconductors at their own facilities while also ensuring a stable supply of multiple product types in small quantities, something that can be challenging to balance with mass production needs.

Starting with porting and manufacture for the 6-inch wafer process, Toppan will handle partial processing related to wafer manufacture, such as epitaxial3 and back-side processes. By March 2025, Toppan will expand the service to the 8-inch wafer process and launch turnkey services ranging from power semiconductor design to manufacture, provided by Toppan Technical Design Center, a subsidiary focused on semiconductor design.

“With this new endeavor we will further bolster our support for the semiconductor industry and device manufacturers,” said Yoshihisa Aida, senior GM of Business Strategy in Toppan’s Electronics Division. “By working with JS Foundry, we will be able to provide an end-to-end service that ensures the supply our customers need and allows them to focus resources on volume production operations.”
