Patent ID: 8310007

Claim:
A semiconductor device, comprising: an n-channel transistor having a source which is connected to a first supply voltage terminal, and a first current control portion which is configured to, when on, inject electrons into an induced drain extension which is created within p-type semiconductor material by an insulated trench which contains sufficient immobile net positive electrostatic charge to invert portions of said semiconductor material, so that electrons flow substantially vertically downward to a drain which is connected to a deep conductive layer; a lateral transistor, having a first source/drain diffusion which is connected to a second supply voltage terminal, and having a second current control portion which controls current between said first source/drain diffusion and a second source/drain diffusion; a vertical conductor which electrically connects said second source/drain diffusion to said deep conductive layer; and an output terminal which is operatively connected to said deep conductive layer and said vertical conductor.
