Depletion-mode transistor that eliminates the need to separately set the threshold voltage of the depletion-mode transistor

摘要

A semiconductor circuit with a depletion-mode transistor is formed with a method that eliminates the need for a separate mask and implant step to set the threshold voltage of the depletion-mode transistor. As a result, the method of the present invention reduces the cost and complexity associated with the fabrication of a semiconductor circuit that includes a depletion-mode transistor.
