摘要： An active circuit element substrate is provided with a matrix array of active circuit elements. Each of the active circuit elements includes 1) a switching element, 2) a capacitor, 3) an electrically-conductive portion connecting the switching element and the capacitor, 4) an insulating layer covering the switching element, the capacitor, and the electrically-conductive portion, and 5) a reflective electrode layer connected to the electrically-conductive portion and extending on the insulating layer. The insulating layer has a surface flat so as to agree with a mirror finished surface. The reflective electrode layer extends on the surface of the insulating layer. A transparent common electrode film extends on a surface of a transparent substrate. An optical modulation layer is located between the reflective electrode layers on the active circuit element substrate and the common electrode film on the transparent substrate. A voltage difference is generated between each of the reflective electrode layers and the common electrode film in response to a signal applied to a control terminal of the related switching element, and light incident to the transparent substrate is modulated by the optical modulation layer in response to the voltage difference and is reflected by the related reflective electrode layer. A light shielding layer covers regions between the reflective electrode layers except portions occupied by metal areas of the active circuit elements as viewed along a direction of incidence of the light. The light shielding layer extends in the insulating layer.

摘要： A magnetic head device for recording signals onto a disk-shaped recording medium such as a floppy disk and reproducing them therefrom is provided. This magnetic head device comprises a magnetic converter unit for conversion of signals to and from a recording medium, a slider member for holding the magnetic converter unit, and a base body on which an optical track position sense unit for optically conducting track position control for the recording medium is affixed. The slider member has a transparent slider surface portion forming an optical path of the optical track position sense unit. A photo detector head chip for servo control used in a magnetic head device as mentioned above is also provided. This photo detector head chip is such that a plurality of light receiving element sections defining a light sensitive area for providing independent light detection signals depending upon a quantity of incident light, and light insensitive sections adjacent to the light sensitive area are alternately formed on the substrate surface, and that at least the light insensitive sections are covered thereon with a light shielding film of, for example, molybdenum or carbon having a small coefficient of reflection. The light shielding film may be formed by a method including the steps of depositing a light shielding material onto an insulating film on the light sensitive and insensitive sections, and applying patterning to the deposited light shielding material so that the light sensitive area is exposed.

At least one pair of pixel switching transistor and a capacitor are formed on a semiconductor substrate. The transistor and the capacitor are electrically isolated from each other. A first interlayer insulating layer is formed on the transistor and the capacitor. A wiring layer is formed on the first interlayer insulating layer. A second interlayer insulating layer is formed over the wiring layer. A light shielding layer is formed on the second interlayer insulating layer. A third interlayer insulating layer is formed over the light shielding layer. At least one pixel electrode is formed on the third interlayer insulating layer. A common electrode is formed over the pixel electrode. A light-transmissive substrate is formed on the common electrode. A liquid crystal layer is provided between the pixel electrode and the common electrode. An anti-reflection layer is formed on, at least, either the wiring layer or the light shielding layer. The anti-reflection layer is a double layer of a metallic film and a silicon oxynitride film that exhibits a refraction index different from a refraction index of the third interlayer insulating layer.
