Abstract
A series of measurements were made on test structures to study the sidegating effect of GaAs MESFETs. The results show that the small portion of the gate of a MESFET that is in direct contact with the semi-insulating substrate plays an important role in causing the observed rapid rise of leakage current and in enhancing the sidegating effect.<>
