  • Patent number: 6316300
    Abstract: A method of manufacturing of a semiconductor device having a thermal oxidation process for selectively forming an oxide film by a thermal oxidation, which can reduce the generation of lattice defects in the semiconductor device during the thermal oxidation process. A groove portion LOCOS oxide film is formed in a groove portion of a semiconductor substrate by first and second wet oxidation steps. At the first wet oxidation step, a thin oxide film is formed on an exposed surface of an epitaxial layer by performing a wet oxidation through an opening portion made of silicon nitride under an oxidation temperature of approximately 875° C. At the second wet oxidation step, the oxidation temperature is risen to approximately 1050° C. to advance the oxidation of the epitaxial layer to finally form the groove portion LOCOS oxide film having a thickness of approximately 950 nm.

  • Patent number: 5714781
    Abstract: A power MOSFET having a groove for forming a channel improved for shortening the switching time and increasing the dielectric breakdown strength of the gate oxide film is disclosed. The power MOSFET includes a concave structure in which a gate oxide film at a groove bottom is thickened. Namely, since the gate oxide film between a gate electrode and a first conductivity type semiconductor layer is thick, the capacitance of the oxide film therebetween is reduced. Therefore, the input and output capacitance of the gate oxide film can be reduced, and switching loss can be also reduced since the switching time can be shortened. Further, greater dielectric breakdown strength of the gate oxide film can be obtained as a result of the thickened gate oxide film at the groove bottom.

  • Patent number: 5610856
    Abstract: An increase in the GND resistance and a drop in the resistance against electromigration are minimized when the ground voltage lines for shunting are finely constituted by using an Al wiring of the same layer as the pad layer, owing to the employment of a layout in which the arrangement of connection holes 24, 26 in a pad layer connected to one (data line) of the complementary data lines and the arrangement of connection holes in a pad layer connected to the other one (data line bar) of the complementary data lines, are inverted from each other every two bits of memory cells in the SRAM along the direction in which the complementary data lines extend.

  • Patent number: 5373471
    Abstract: In case an address is to access a defective memory cell, a defective memory cell in a memory cell area contained in one of paired memory mats is selected in parallel with a redundant memory cell in a redundant memory cell area contained in the other memory mat. At this time of selecting the redundant main word line for selecting the redundant memory cell, there is not required the logical operation for deciding whether or not the redundant use of the access address fed from the outside is proper. For example, the redundant main word line is set to the select level on the basis of a chip select signal. As a result, the drive start timing of the redundant main word line is not delayed in the least from the drive start timing of the main word line. Thus, it is possible to prevent the event that the select drive timing of the redundant sub word line is delayed on account of the delay in the drive timing of the redundant main word line.
