Abstract: PURPOSE:To ease the constriction of the drain current of a GaAs Schottky gate field-effect transistor and to reduce the leakage gate current and source resistance. CONSTITUTION:An i-type insulating film 2 of a required width or less whose hole trap and electron trap densities are balanced is provided on the drain-side side wall of the gate electrode 30 of a GaAs Schottky gate field-effect transistor. On the other hand, an n-type insulating film 1 having excessive hole traps is provided on the source side of the gate electrode 30. Surface depletion layers being in a state of deep depletion are produced locally only on the surface of an n-type operation layer 50 just under the i-type insulating film 2 on gate side walls and in the end part of the drain-electrode 32 side gate electrode. Accordingly, the constriction of the drain current and gate leakage current are both small, and the source resistance can be reduced.

IPC: G09F9/35
Filed: 1990-11-14
Abstract: PURPOSE:To prevent the degradation in the characteristics of elements, such as liquid crystal light valves, by disposing dichroic mirror (DM) having the wavelength selection width of spectral characteristics narrower than the selection width of a color separating dichroic prism (DP) and a color synthesizing DP in the optical path between the DP and the liquid crystal light valves. CONSTITUTION:The light of the wavelength region inclined by the spectral characteristics of red and blue reflecting mirrors (P) 20, 21 is not completely separated and is made incident straight on the color synthesizing DP 9 at the time when the white light of projecting light 11 is separated to red, green and blue by the color separating DP 5. A part of this light is made incident on the liquid crystal light valves from the direction reverse from the projecting light and degrades the characteristics of the elements. If the DM is disposed in the optical path between the DP 5 and the respective liquid crystal light valves, the light of the wavelength region inclined by the spectral characteristics of the reflection mirrors (P) 20, 21 transmits the Dm and is expelled to the outside of the optical system as the wavelength selection width of the respective DMs is set narrow. Then, the quantity of the incident light on the liquid crystal light valves from the opposite direction decreases.
