Title: Manufacture of field-effect transistor
Inventor: FUJII MASAHIRO
IPC: H01L29/778
Filed: 1987-03-06
Abstract: PURPOSE:To build FETs of different threshold values on one and single semi- insulating substrate by a method wherein an n-layer or p-layer is selectively formed on the substrate and, by using the layer, a second semiconductor layer low in electron affinity and high in purity is stacked up, and then ohmic electrodes are built on both sides of a Schottky electrode. CONSTITUTION:Si ions 19 are selectively implanted into a semi-insulating GaAs substrate 10 with a photoresist 18 serving as a mask, and the quantity of implantation is changed. Annealing is accomplished after an Si3N4 coating is provided, which results in n-type GaAs layers 12 and 112. The Si3N4 film is removed and then an undoped Al GaAs layer 13 is formed by molecular beam epitaxy, to be stacked up. On the surface, an Al gate electrode 14, AuGe 15, and Ni 16 are evaporated. Heating is accomplished, which continues until an alloy layer 17 reaches as far as the n-type GaAs layers 12 and 112 for the building of source.drain electrodes. This method enables a plurality or FETs of different threshold voltages VT to be constructed on one and single substrate.
