Abstract
The edge of a conformal coating over a mesa is usable to define a shoulder in the vertical dimension of the mesa which in turn is used for positioning. Structures are provided that permit electrodes at precise locations along the length of a mesa. A vertical field effect transistor is set forth with a mesa serving as the channel and the gate electrode positioned at a shoulder formed by the edge dimension of a coating on the sides of the mesa.
