Title: Light-controlled fet
Inventor: NONOYAMA ATSUSHI
IPC: H01L21/338
Filed: 1992-01-28
Abstract: PURPOSE:To provide a MESFET with which the carrier trap in an active layer by a method wherein a LED is buried in a buffer layer, and a beam of light is made to irradiate on a FET by applying a current thereon. CONSTITUTION:An undoped GaAs buffer layer 2 is formed on a semi-insulating GaAs substrate 1, a P-GaAs layer 3 and an n-GaAs layer 4 are laminated thereon. An electrode A is formed making contact with the P-GaAs layer 3, and an electrode K is formed making contact with the n-GaAs layer 4, an AlAs insulating layer 5, a GaAs buffer layer 6 and an n-GaAs active layer 7 are laminated on the n-GaAs layer 4, and a source S, a gate G and a drain D, which functions as a MESFET, are formed on the active layer. The potential of electrodes A and K is separated from FET by the AlAs layer 5, but the light generated by the current between both electrodes passes through the AlAs layer 5 and the GaAs layer 6, arrive at the uppermost GaAs 7, and changes the conductivity of the FET. At this time, as irradiation light excites the electrons of the trap level in each layer, backgate effect can be suppressed.
