ProPowertek makes a breakthrough in 1.5 Mil Taiko Wafer with High Wafer Strength

2021-01-06 ProPowertek

With the booming development of 5G, IoT and electric vehicles, the requirements for low power consumption are getting more and more demanding, which makes power semiconductors become an irresistible and essential component for these industries. To meet the requirements of customers, Prosperity Power Technology Inc. (abbreviated as ProPowertek) announces today (January 6, 2021) that it has made a breakthrough in 1.5 mil (38um) taiko wafer with high wafer strength, which has been recognized by customers.

ProPowertek pointed, wafer thinning has been the most direct and effective process improvement in cutting power consumption and input impedance of power semiconductors which not only reduce packaging dimension but also extends the operating life of wafers by lowering RDS (on) and heat accumulation.

However, the MOSFET foundries are facing a challenge of balancing thinness and strength of wafers to minimize the risks of soaring rate of broken wafers.

ProPowertek is not only to exclusively develop the thinning technology for wafers 2mil(50um), 1.5mil(38um), and even 0.4mil(10um) thick, but also strengthen wafers by reducing stress accumulation at the damage layer with its optimized process.
