Abstract
A trench semiconductor power device having active cells under gate metal pad to increase total active area for lowering on-resistance is disclosed. The gate metal pad is not only for gate wire bonding but also for active cells disposition. Therefore, the device die can be shrunk so that the number of devices per wafer is increased for die cost reduction. Moreover, the device can be packaged into smaller type package for further cost reduction.
