Title: Manufacture of semiconductor device
Inventor: HASEGAWA NORIO
IPC: G03F1/32
Filed: 1998-04-16
Abstract: PROBLEM TO BE SOLVED: To form an effective dark part without adding a shading film, and further form a practically useful translucent phase shift film without adding a mask formation process by forming a translucent phase shift part and a transmission part in an optimum dimensional combination. SOLUTION: A zone 3 acting as a shading part is formed on the wafer where a transparent substrate is provided, element patterns having an array of translucent phase shift parts and transmission parts are arrayed and translucent phase shift patterns are arrayed at a pitch less than a resolution limit. Furthermore, transparent pattern parts 5 are formed in the translucent phase shift part 3. The arrangement pitch 6 of the transparent patterns 5 is decided, depending on the resolution characteristic of a projection optical system to be used. Also, the arrangement pitch P is expressed by the formula of P=α.λ/NA, where NA is the numerical aperture of a projection lens, λ is exposure wavelength and α is factor.  In this case, the factor α is experimentally taken at a value equal to less than 0.8 preferably, but an optimum value is not limited thereto, because the value depends on the characteristic of an illumination system, a pattern shape or the like.

Filed: 1989-04-28
Abstract: PURPOSE:To enable heat treatment in the mild conditions and to obtain giant particles or single crystal of chromium by heat-treating a molded chromium body contg. Si or Co wherein a strain has been formed by sintering. CONSTITUTION:The aimed giant particles or single crystal are obtained by heat-treating a molded chromium body contg. Si and/or Co wherein a strain has been formed by sintering. As one method for adding necessary amount of Si component to chromium component, such a method that SiO2 is previously added to chromium component e.g., chromium oxide for obtaining chromium is utilized and this method is preferable even in the above-mentioned method. Further as a method for adding Co to chromium, any stage of both addition to chromium itself and addition in the metallizing stage of chromium may be utilized. It is favorable that necessary amount of Co is incorporated in the molded chromium body at a point of time for the ensuing sintering of chromium. The amount of Co added to chromium is regulated to 0.01-3.0wt.%. When the amount of Co is less than 0.01wt%, effect of cobalt addition is insufficient and when it is more than 3.0wt.%, reversely adverse effect affects single crystallization of chromium.
