    摘要: A method of manufacturing semiconductor device wherein the self-alignment technique is employed to simplify the manufacturing process and includes the steps of successively depositing multiple layer masking films comprising a first, a second and a third masking films on an n-type Si region, forming an island region of the multiple layer films and a peripheral portion of the second masking film which is etched away, by side-etching, from the edges of the other masking films, selectively forming an oxidized film, selectively etching the first oxidized film using the second masking film as a mask and forming fine contact windows between the selectively formed oxidized film and the first masking film, depositing a semiconductor thin film, lifting-off the semiconductor thin film by removing the second and third masking films and leaving a portion of the semiconductor film which contacts the windows, oxidizing the surface of the semiconductor thin film and removing the first masking film.

    摘要: A novel MOS field effect transistor which operates at high speed and with low power consumption has impurity doped source and drain regions deposited at 850.degree. C. or less by molecular layer epitaxial growth method. The molecular layer epitaxial growth is concurrently carried out with the control of impurity doping concentration so that the layers epitaxially deposited has a lightly doped region and a heavily doped region. Since the thickness of the growth layer can be controlled with a degree of accuracy on the order of an atom layer and thermal diffusions can remarkably be reduced by the low deposition temperature, an overlap of a gate over each of the source and drain regions can be reduced to 500 .ANG. or less.

    摘要: A method of manufacturing an integrated circuit device including vertical static induction transistors (SIT) having a first recess between the gate region and the drain (or source) region to reduce the capacitance between both regions and a second recess on an outer surface of the SIT gate to reduce the gate capacitance and a minority carrier storage. The method includes the steps of removing a masking film on the SIT channel region while leaving the masking film at the portions of the gate region and the drain region; forming the first and the second recesses in the channel region; locally oxidizing the exposed channel region; and forming the gate region and the drain region by removing the masking film.

    摘要: A method of fabricating a semiconductor device comprising forming an island-shaped multi-layered structure of oxides and nitrides on the surface of a semiconductor. The multi-layered structure is selectively etched to define diffusion windows for forming a semiconductor structure in the semiconductor surface having a central region of one conductivity type surrounded by another region of a different conductivity type. A second island-like multi-layered structure is formed and is etched for controlling the duration of the etching steps by controlling the amount that the masks lift off from the insulation layers subjected to etching. The etching is carried out by side etching.

    摘要: A semiconductor device of the complementary metal-insulator semiconductor type is composed of a pair of N-type metal oxide semiconductor transistor formed on a P-type silicon substrate and P-type metal oxide semiconductor transistor formed on an n-type well disposed within the p-type substrate. An isolation tranch is disposed between the pair of adjacent transistors, and has one sidewall bordering the well, another opposed sidewall bordering the substrate, and a bottom wall. A selective epitaxial film of p-type is selectively epitaxially deposited on the sidewalls and bottom wall of the trench. The epitaxial film has a dopant density greater than that of the substrate. An insulation oxide material is filled within the trench so as to effectively isolate the pair of transistors from each other.
