Abstract :
A method for extracting the effective channel thickness of MESFETs fabricated in fully ion-implanted processes is proposed. This method is based on the measurement of the transconductance parameter β. Since the expression for β includes the velocity saturation effect, the extracted effective channel thickness is comparable to simulation results. This method allows convenient extraction of the effective channel thickness of fully implanted MESFETs
