Abstract: PURPOSE: To simplify the manufacturing process of bipolar type IC, by providing the implanted region of low impurity concentration on the semiconductor substrate, growing the epitaxial layer of opposite conduction type on it, and obtaining the specified collector resistance value with mutual compensation of the impurity in the implanted region and the epitaxial layer.  
     CONSTITUTION: The N type implanted region 2 having lower concentration than the impurity concentration conventionally used is formed on the P type Si substrate 1, and the P type layer 3 is epitaxially grown on the entire surface. Next, the layer 3 is passed through and the N type region 4 reaching the substrate 1 is formed with selective diffusion, and the concentration of the region 4 is selected so that the impurity of N type at the region 4 and the P type impurity of the layer 3 can be mutually cancelled and suitable resistance value can be obtained to the collector. Simultaneously, the N type is increased to the part overlaid for the regions 2 and 4 and the series resistor is lowered. After that, the P type separation region 5 is formed by diffusion until it reaches the substrate 1, and the regions 2 and 4 and the layer 3 are isolated in island manner. After this, the P type base region 6, N type emitter region 7, and collector contact region 8 are formed in conventional way.

IPC: G02F1/055
Filed: 1984-07-31
Abstract: PURPOSE:To obtain an optical shutter to be driven at a low voltage by applying resist, cutting off a groove by a scriber dither, evapolating a metallic thin film, and then lifting off an unnecessary metallic thin film. CONSTITUTION:Photoresist is applied to transparent ceramics 1 having Kerr effect and the applied photoresist is exposed and developed through a photomask to form a prescribed pattern. The pattern is formed so that the resist is left on the parts from which electrodes are removed. The grooves 2 are cut off by the scriber dither and a metallic thin film such as aluminium is evapolated on the whole surface. Since the resist is not applied to the insides of the grooves 2, the metallic thin film is also evapolated to the insides of the grooves 2 by circulation. After evapolation, the resist is dissolved in a solvent to remove an unnecessary metallic thin film and to form an optical shutter.

Abstract: PURPOSE: To achieve the improvement in response speed and evenness of display by defining the angle that the molecular axes of liquid crystal and dyes and the normal of transparent electrodes assume to the specific range in the state where no voltage is applied.  
     CONSTITUTION: Diagonal vapor deposition of electrodes is done on transparent electrodes, after which orientation treatment is applied so that the angle θ that the molecular axes of guest and host and the normal of the transparent electrodes 2 assume is 3W30° when there is no applied voltage. The transparent glass substrates 1 are then parallel disposed at the specified spacing in such a manner that the surfaces of the transparent electrodes oppose to each other. The mixture of dichromatic dyes 5 and nematic liquid crystal 4 is put between these substrates and the assembly is sealed by a spacer 3. With this constitution, the molecular axes of guest and host remain stable not in the direction perpendicular to the glass substrates 1 but in a state inclined by the angle θ thereto where no voltage is applied and therefore the moving directions of the molecular axes of guest and host when voltage is applied coincide, as a result of which response speed increases and the even display free from variable densities is obtainable.
