Abstract
Various embodiments of a power MOS device structure are disclosed. In one aspect, a power MOS device structure includes a plurality of LDMOS and a plurality of bonding pads. The basic units of LDMOS are coupled in parallel and electrically coupled to the bonding pads to couple to a gate terminal, a source terminal, a drain terminal and a substrate of each of the basic units of LDMOS. The basic units of LDMOS are disposed below the bonding pads. The bonding pads include a single layer of metal with a thickness of 3.5 um to 4.5 um and a width of 1.5 um to 2.5 um. The region below the bonding pads of the power MOS device of the present disclosure is utilized to increase the number of basic units of LDMOS, thereby effectively reducing the on-resistance.
