    • PURPOSE: A semiconductor exposure apparatus is provided to be capable of freely varying the shape of an aperture loaded in the apparatus by using an LCD(Liquid Crystal Display) as the aperture. CONSTITUTION: A semiconductor exposure apparatus is provided with a light source(51), an aperture(53) for selectively transmitting the light irradiated from the light source, a mask(59), a reflective mirror(57) installed between the aperture and the mask for reflecting the light transmitted from the aperture to the mask, and a condensing lens(61) for irradiating the light supplied from the mask toward a wafer(W) while condensing the light. At this time, the aperture is capable of electrically and partially controlling the pass and stop of the light irradiated from the light source, so that the shape of the aperture loaded in the exposure apparatus is capable of being changed. Preferably, an active matrix type LCD device is used as the aperture.

    • PURPOSE: A method for varying a transmission degree of a scattering bar to control a pattern size is provided to vary the size and profile of a pattern on a wafer such that the pattern is formed by transcribing a main pattern shape to the wafer by making the transmission degree of a scattering bar introduced as an assist pattern to the periphery of a main pattern different from that of the main pattern when the transmission degree of the main pattern in a photomask is set at a predetermined transmission degree. CONSTITUTION: A photomask is introduced to a photolithography process to transcribe a pattern image to a wafer. The transmission degree of a scattering bar introduced to the periphery of a main pattern for embodying the pattern image is varied. The transmission degree of the scattering bar that varies the size and profile of a pattern formed on the wafer is varied to control the size of the pattern.
