摘要:
A semiconductor component that includes gate electrodes and shield electrodes and a method of manufacturing the semiconductor component. A semiconductor material has a device region, a gate contact region, a termination region, and a drain contact region. One or more device trenches is formed in the device region and one or more termination trenches is formed in the edge termination region. Shielding electrodes are formed in portions of the device trenches that are adjacent their floors. A gate dielectric material is formed on the sidewalls of the trenches in the device region and gate electrodes are formed over and electrically isolated from the shielding electrodes. The gate electrodes in the trenches in the device region are connected to the gate electrodes in the trenches in the gate contact region. The shielding electrodes in the trenches in the device region are connected to the shielding electrodes in the termination region.
