Vishay, Tower expand chip manufacturing partnership
Specialty foundry Tower Semiconductor is expanding the portfolio of power semiconductor products for automotive markets that it will make for Vishay Intertechnology Inc.

Tower Semiconductor Ltd. (Migdael, Haemek, Israel) trades as TowerJazz. Vishay Intertechnology trades as Vishay Siliconix.

The existing and next-generation power devices will be made at two o Tower's IATF16949 qualified manufacturing facilities. According to Tower's website both its wafer fab at Migdal Haemek, Israel and its fabs in Newport Beach, California, and San Antonio, Texas are qualified to IATF16949.

Vishay's automotive dedicated platforms will enable improved efficiency of power management circuitry in reduced volume, Tower said in a statement.

Vishay has used Tower's Transfer Optimization and development Process Services (TOPS) to transfer low- and high voltage MOSFET processes into the foundry. These services include the development of next-generation custom processes, technological capabilities with manufacturing capacity assurance and flexibility.

"Ranking as Vishay Siliconix' number one foundry while continuously supporting growing market activities, this expansion recognizes TowerJazz's valuable continued commitment, exceptional technical and customer support, strong collaboration, and delivery performance," said Serge Jaunay, head of Vishay's MOSFET division.

According to IC Insights, the automotive IC market reached a value of of $32.3 billion in 2018. The market is expected to remain the fastest growing IC market with a compound annual growth rate of 12.5 percent to take its value to more than $43 billion in 2021. This market is expected to be dominated by analog ICs, power management including power MOSFETs, visual and non-visual sensors, RF, and lighting.

Tower is set to see a a reduction in revenue of US$80 million per year from a three-year extension to its deal to supply Panasonic Semiconductor out of three manufacturing facilities Tower controls in Japan.
