Title: Exposure device
Inventor: NAGAI SHINICHIRO
IPC: G03B27/72
Filed: 1994-12-28
Abstract: PURPOSE: To provide an exposure device which can be miniaturized while uniformizing the illuminance of exposing light. CONSTITUTION: This device is constituted of a mercury lamp 1, an elliptic mirror 2, a dichroic mirror 3, an optical integrator 4, a band-pass filter 5, a condenser lens 6, a mask 7, a projection lens 8 and a heat sink 9. Even when the maximum divergence angle α of the exposing light made incident on the band-pass filter 5 is set large, for example, 5 deg. to 20 deg., in the case of designing the band-pass filter 5, the passing band of the band-pass filter 5 is deviated to a long wavelength side in accordance with the maximum divergence angel α, so that peripheral light on the long wavelength side of the exposing light is allowed to pass the filter 5 satisfactorily.  On the other hand, in the case the incident angle is 0 deg., the exposing light on the low wavelength side is out of the passing band, so that the illuminance of the exposing light irradiating an object to be exposed 10 is uniformized. Therefore, the maximum divergence angle α is made large and the length of an optical path is shortened, thereby miniaturizing the device.

Abstract: PROBLEM TO BE SOLVED: To increase the surface area of a capacitor electrode and hence drastically increase capacitance more than before, by forming a first projecting part on the capacitor electrode and a second projecting part with a particle diameter smaller than the fist projecting part on the surface of the first projecting part. SOLUTION: In a first step, an HSG grain with a particle diameter of approximately 0.1 μm is formed on the surface of a capacitor electrode.
