IPC: G06T7/60
Filed: 1989-09-14
Abstract: PURPOSE:To detect an edge position with extremely high accuracy by counting the picture elements including the part overlapping a prescribed oblique straight line of a binary image and deciding the boundary position between the bright and dark parts based on the differential value of the counted picture elements. CONSTITUTION:A screen is scanned with use of a prescribed oblique straight line having the same color as a bright or dark part, and a part overlapping the oblique straight line and the bright or dark part of a binary image is obtained. The picture elements including the overlapping part are counted for each scanning position, and the differential value of the obtained picture element number data is calculated. Based on this differential value, the boundary position is obtained between the bright and dark parts. Thus the picture elements included in an overlapping part between a binary image and a prescribed oblique straight line are counted for each scanning position. Then the differential value of the count value is obtained. As a result, an edge position is detected with extremely high accuracy with no influence caused by the tilt of the boundary, the complication of boundaries, etc.

IPC: H01L21/027
Filed: 1996-09-09
Abstract: PROBLEM TO BE SOLVED: To form a pattern with a small roughness, to make control of the pattern dimension easy, to reduce faults in the succeeding processes such as etching and ion injection, and to improve the production yield of the element, by incorporating a specified compd. and a solvent which dissolves the compd. SOLUTION: A low mol.wt. compd. expressed by the formula is used as a polymer. In the formula, R1 to R3 are desired substituents and n is an integer of 0 to 6. By using the pattern forming material containing the polymer and forming a pattern by an electron beam drawing method, an extremely fine pattern having 0.15μm line-and-space period can be obtd. while the surface roughness of the pattern can be suppressed to <=1nm. Therefore, by using a pattern forming material containing a low mol.wt. compd. which can be formed as a resist film, the surface roughness can be suppressed to a small value even when the pattern is formed by electron beam drawing.
