Title: Growth of selective silicon epitaxial film
Inventor: SUZUKI TATSUYA
IPC: C30B25/14
Filed: 1995-08-23
Abstract: PROBLEM TO BE SOLVED: To prevent a facet from being formed on the sidewalls of a selective silicon epitaxial film by a method wherein atomic hydrogen is adsorbed to the surface of the silicon epitaxial film by introducing the atomic hydrogen in the silicon epitaxial film along with raw gas and the surface free energy of the silicon epitaxial film is significantly reduced to reduce the crystal face orientation dependence of the free energy. SOLUTION: When hydrogen gas is made to pass through a W filament 7 heated at a high temperature by a power supply 8 for filament use, 5% or thereabouts of the gas is dissociated into atomic hydrogen. By introducing the atomic hydrogen in a selective silicon epitaxial film even on a growth condition that the temperature of a substrate is high and the flow rate of raw gas is low, a high hydrogen coverage on the surface of the silicon epitaxial film becomes possible like a growth condition that the temperature of the substrate is low and the flow rate of the raw gas is high. Thereby, the crystal face orientation dependence of the surface free energy of the silicon epitaxial film is reduced. As a result, the formation of a facet on the sidesall parts of the film can be inhibited.

Title: Nonvoltatile semiconductor storage device
Inventor: YAMAMOTO YASUHIRO
IPC: G11C29/50
Filed: 1997-08-08
Abstract: PROBLEM TO BE SOLVED: To obtain a device capable of evaluating other memory cells by impressing a selection potential on plural nonvilatile memory cells and a word line and impressing a nonselection potential lower than the selection potential on nonselection word lines at the time of a normal mode and impressing the selection potential on word lines selected from the plural word lines and impressing a potential lower than the non-selection potential on nonselection word lines at the time of a prescribed mode. SOLUTION: In this flash memory, since the potential of nonselection word lines is made a negative potential, electrons are drawn out excessively from floating gates 404d and threshold voltages become lower than a grounded potential at the time of a programmed operation. In short, data of memory cells connected to the same subbit line 403 as that of the overprogrammed memory cells 404 are read out and it is possible to perform the evaluation of the data. Since the potential of the nonselection word lines can be made to be a negative potential lower than the grounded potential, the over-programmed memory cells 404 are made to be in nonconduction states at the time of a, non-selection, the evaluation is made possible without being affected by the memory cells.
