Title: Semiconductor device
Inventor: FUKUDA HIROSHI
IPC: H01L27/10
Filed: 1988-06-20
Abstract: PURPOSE:To shorten the length in the longitudinal direction of a work line in cell array so as to enable the area of the entire cell array to be reduced by varying only the internal between a pair of data lines holding a column selecting line from those between other data lines, and narrowing the intervals between other data lines than that column of a pair of data lines. CONSTITUTION:A column selection line 14 is arranged between data lines 7a and 7b, and only that interval differs from the intervals of other data lines 7. That is, the intervals between data lines that the column selection line 14 does not pass become the minimum intervals regulated by stipulation of wiring such as wiring capacity, etc. Since the data lines 7 at the positions that the column selection line 14 does not pass in memory mats A1, B1, A2 and B2 are separately arranged at minimum intervals, the length of the unit d is shortened. Accordingly, the lengths in the Y direction of the memory mats A1, B1, A2 and B2 are shortened, and the entire area of the cell array is reduced.

Title: Anisotropy etching device
Inventor: OI HIROYUKI
IPC: H01L21/306
Filed: 1998-05-29
Abstract: PROBLEM TO BE SOLVED: To provide an anisotropy etching device that can stabilize the anisotropy etching of the surface of a semiconductor wafer, and at the same time, reduce the number of μpyramids being generated on the etching surface of the semiconductor wafer. SOLUTION: A surface inside the tank of a ceiling board 12a of a lid body 12 is slanted, and the falling position of a droplet is allowed to deviate from the anisotropy etching liquid surface part of the upper part of a silicon wafer W. As a result, the frequent occurrence of a μ pyramid on a wafer etching surface can be suppressed. In addition, the evaporation constituent of IPA is subjected to droplet and is returned to an IPA rich layer (a), thus reducing the composition change of anisotropy etching liquid and at the same time, risk where the temperature of the liquid becomes low, and hence simultaneously stabilizing the anisotropy etching liquid of the silicon wafer W on anisotropy etching.
