Title: Semiconductor device and method for manufacturing the same
Inventor: ATSUMI KENJI
IPC: H01L21/205
Filed: 2001-07-02
Abstract: PROBLEM TO BE SOLVED: To provide a semiconductor device, by which the degrading or yield caused by misfit shifting in an epitaxial silicon film is reduced though the epitaxial silicon film and a polycrystal silicon film on a monocrystal silicon film lie in a row with each other. SOLUTION: An SiON film 38 is an insulation film below a silicon film. Thus, by controlling the ratio of silicon, oxygen and nitride, it is possible to make the thermal expansion coefficient of the insulating film close to the thermal expansion coefficient of silicon. Consequently, during the manufacturing process of the semiconductor, after forming the silicon film, stress caused by the difference between the insulation film and the thermal expansion coefficient will not occur easily in the polycrystal silicon film on the insulating film. Thus, the epitaxial silicon film is not easily given stress from the polycrystal silicon film.

Title: Method of writing data into memory, data write processing program and data write device
Inventor: KOREKI TAKU
IPC: G11C16/02
Filed: 2001-07-03
Abstract: PROBLEM TO BE SOLVED: To improve write processing speed and processing efficiency and to contribute in longer life of memory. SOLUTION: Parameters to be stored in a sector n in a flash ROM are brought together in one block, and the data size SIZE of the parameter block for which the parameters are brought together in one block is calculated (step S1). Besides, in the sector n, by the processing in steps S4 to S8, a balance check is made to find whether or not a memory area has a blank area equivalent to the parameter size SIZE. In addition, if the determination result in the step 8 is NO and the blank area size is equal to or more than the parameter size SIZE, it is meant that an area, in the sector n, equivalent from an address indicated by adrs to the parameter size SIZE is in a blank state and is write enabled. In this case, thus, an address that a variable for address adrs indicates in the sector n is determined as a writing start address for the parameter (step S9).
