摘要： An active matrix reflective liquid crystal device includes an array substrate which includes switching elements corresponding to pixels and an array of pixel electrodes connected to the switching elements; and an opposing substrate which has a transparent electrode opposite the array of pixel electrodes with a liquid crystal layer inserted therebetween. Each of the pixel electrodes includes an array of electrode studs, (e.g., divided electrode elements). The regions between the electrodes are filled with an insulating material, and the surface of the stud array is planarized by chemical-mechanical polishing (CMP). A dielectric light reflective film is formed on the planarized surface of the stud array, and a liquid crystal molecule alignment film is deposited thereon. Thus, a reflection type liquid crystal device is provided having a planarized light reflective face for a reduced reflection loss, along with a method for manufacturing the same, and a projection display system using such a reflection type liquid crystal device.

摘要： Disclosed is a pattern inspection apparatus which easily and highly accurately detects a profile error (deviation) of at least one pattern having a cross section with projections and recesses. The inspection apparatus for the pattern 32 is for detecting the profile error of the pattern having a cross section with a projection and a recess. This inspection apparatus includes a plate 30 on which a pattern is mounted, light sources 40, 42 and 44 which can change angles of illuminating light emitted onto the pattern, within a range of 15 to 75 degrees with reference to the top surface of the pattern, and photodetectors 52 and 54 which can receive reflected light from the pattern at an angle within a range of 15 to 75 degrees with reference to the top surface of the pattern. The inspection apparatus is characterized by that the profile error of the pattern is detected based on an amount of the reflected light from an edge between the top surface and the side surface of each of the patterns.
