Mid-end and backend process technology (WETIntegrationMetal depositionLithography engineer)

SPS (Smart Power Stage) products are expected to see significant demand growth from 2025 to 2030 with a particular surge in demand for AI servers. These devices especially embedded VPS such as PT (Power Tower Module) and VPS (Vertical Power Stage) require Mid-end processes such as Cu-RDL backside metal and ultra-thinning of Si which also help differentiate from competitors.

Renesas is strengthening in-house manufacturing and as part of this we plan to develop technologies for these Mid-end processes secure production capacity and shorten LT through in-house production. These in-house productions are also strongly requested by customers. Going forward chiplet technology that maximizes performance while reducing manufacturing costs and shortening development periods will increasingly require Mid-end processes such as RDL and bumps.

This time we are recruiting personnel who understand the structure and characteristics of power devices and can build optimal processes from Mid-end processes such as RDL and OPM to back-side processes and dicing as we internalize embedded VPS. By acquiring personnel well-versed in Mid-end and backside processes it becomes possible not only to develop internal processes but also to respond to issues in OSAT.

We are seeking process engineers in the following four areas:
