Abstract
A metallization structure of distributed gate drive enabling the switching behavior of different MOSFET arrays and fingers to be more unified while maintaining the same Rdson and Qg performance. This balances the transient current between MOSFET arrays and fingers during switching, allowing the device to operate at a much higher current.
Claims15
A semiconductor device, comprising:
- a semiconductor die formed with a plurality of transistor arrays forming a monolithic power stage or point-of-load device;
- a routing metallic layer electrically coupled to each gate of each transistor of said plurality of transistor arrays;
- and
- a plurality of gate drivers positioned along a periphery of said semiconductor die and electrically coupled to each gate of each transistor of said plurality of transistor arrays through said routing metallic layer.
