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

TAIPEI,Jan. 6,2021 -- 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,iST,Integrated Service Technology Inc. (TWSE: 3289) has put more efforts in its wafer backend process fab (Hsinchu Science Park Building 2) and announces today (January 6,2021) that it has made a breakthrough in 1.5 mil (38um) taiko wafer with high wafer strength. Meanwhile,to be more focused on serving international customers,iST has established Prosperity Power Technology Inc. (abbreviated as Propowertek),with immediate effect.

iST 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 packagingdimensionbut 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.

iST is not only toexclusively 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 layerwith its optimized process.

iST can providecustomized solutions to enhancewafer for Power MOSFET/IGBT and other components.For any inquiries,just ring Mr. Liu at +886-3-579-9909 EXT 5001 or email us atweb_sp@istgroup.com
