    摘要: An AND flash memory of the type wherein a memory cell is constituted of n-type semiconductor regions (a source and a drain) formed in a p-type well of a semiconductor substrate and three gates (including a floating gate, a control gate and a selective gate) is manufactured. In the manufacture, arsenic (As) is introduced into a p-type well in the vicinity of one of side walls of the selective gate to form n-type semiconductor regions (a source and a drain). Thereafter, to cope with a drain disturb problem, the substrate is thermally treated by use of an ISSG (In-Situ Steam Generation) oxidation method so that a first gate,insulating film disposed in the vicinity of one of side walls, at which the n-type semiconductor regions have been formed, is formed thick.

    摘要: A non-volatile semiconductor memory device provides for higher integration by reducing the area of occupation of direct peripheral circuits, in which the memory cell of an AND type flash memory includes a selection gate, a float gate, a control gate that functions as a word line, and an n-type semiconductor region (source, drain) that functions as a local bit line. A pair of local bit lines adjacent to each other in a memory mat are connected with one global bit line at one end in the direction of the column of the memory mat, and a selection MOS transistor, formed by one enhancement type MOS transistor and one depletion type MOS transistor; is connected in series with each of the pair of local bit lines. One of the local bit lines is selected by turning the selection MOS transistor on/off.

    摘要: A silicon-rich oxide (SRO) film is arranged over an uppermost third-level wiring in a semiconductor device. Then, a silicon oxide film and a silicon nitride film lying over the third-level wiring are dry-etched to expose part of the third-level wiring to thereby form a bonding pad and to form an opening over the fuse. In this procedure, the SRO film serves as an etch stopper. This optimizes the thickness of the dielectric films lying over the fuse.
