Abstract:VDMOS has the advantages of bipolar transistors and common MOS devices,and is widely used in power supply circuits. Aiming at the problem that the packaging technology in domestic VDMOS device production can not meet the insulation requirements,a stacked internal insulation packaging technology for VDMOS devices is proposed,which can improve the heat dissipation performance and insulation strength during the period. The power device chip was optimized and the comprehensive performance of the products was improved. The BRCS740R and BRCS840D series products with self insulation function,good heat dissipation performance and bearing greater power loss were designed and produced,which filled the production gap of domestic industry.

Keywords:VDMOS;stacking;packaging;process design
