TANAKA’s Longstanding Leadership in Precious Metal Sputtering Targets for the HDD and AI Data Storage Era

TANAKA`s sputtering targets for thin film deposition used for semiconductor industry

TANAKA began mass-producing sputtering targets using precious metals in the 1980s as materials for thin film formation using physical vapor deposition (PVD). In the 2000s, in line with the evolution of Hard Disc Drives (HDDs), we began development and production of targets made of platinum alloys, and ruthenium for perpendicular magnetic recording, continuously providing stable supply to the HDD industry. We have also established recycling technology to recover and reuse the scrap generated from our customers’ manufacturing processes and sputtering equipment, contributing to the circular economy of precious metals. 

HDD is a storage technology known for its cost performance and large-capacity storage and is expected to see stable market growth. There are expectations of accelerated investments in the data center and AI fields in recent years. This strategic focus on AI is expected to further accelerate the need for next generation storage technologies—an area where TANAKA’s expertise in manufacturing high-grade sputtering targets using precious metal materials will remain indispensable. 

As a precious metal professional, TANAKA remains committed to meeting customer needs by delivering high-quality, high-performance products through advanced manufacturing and innovation.
