Title: Semiconductor device
Inventor: MATSUOKA NAOYUKI
IPC: H01L29/778
Filed: 1987-12-23
Abstract: PURPOSE:To alleviate a crystal lattice distortion and to obtain a high carrier concentration by forming a delta-doped monoatomic layer containing doped atoms on the boundary of a hetero junction. CONSTITUTION:An undoped GaAs layer 102, a delta-doped monoatomic layer 103 having Si as doping atom, and an undoped AlxGa1-xAs layer 104 are sequentially grown by epitaxially growing on a semi-insulating GaAs substrate 101. Then, after a gate electrode 106 is formed, with it as a mask source, drain electrodes 105 are formed by ion implanting, and an ohmic electrode 107 is formed. Since the layer 103 is disposed in a hetero boundary of the layers 102 and 104, even if the concentration of the Si atoms of an impurity is high, a lattice distortion is alleviated in the boundary, and since the layer 103 is formed on the hetero boundary, mutual action between the Si atoms is small, thereby obtaining a high carrier concentration.

Title: Method for polarization
Inventor: OBAYASHI YASUSHI
IPC: G02F1/37
Filed: 1989-12-15
Abstract: PURPOSE:To accomplish a polarization by applying an electric field between electrodes at both the ends of an optical crystal in such a way that high-temperature, electrically conductive porous forms are put between the optical crystal and the electrodes to prevent the metal from the electrodes from diffusion as impurities into the optical crystal. CONSTITUTION:Both the surfaces of an optical crystal 1 are fitted with electrodes 2, 2, respectively, and the resultant system is put in a heating furnace 3. In this case, metallic plates such as platinum ones with low diffusion coefficient into the optical crystal 1 are used as the electrodes 2, and porous crystal forms 5 are put between the optical crystal 1 and the electrodes 2. To make the contact of the porous crystal forms 5 firmer, a paste 6 is applied between the porous crystals 5 and the optical crystal 1. Thence, an voltage is applied between the two electrodes 2, 2 and the system is heated to a level near the Curie point where the system is held for a specified time, followed by cooling the system to room temperature while applying a voltage, thus completing the treatment for single domain development. Use, as the porous form 5, of a sintered compact produced by calcining mixed powder with the same composition ratio as that for the optical crystal 1 will cause no possibility of impurity contamination from the sintered compact.

IPC: B24B37/013
Filed: 1992-12-07
Abstract: PURPOSE:To minimize a measurement error by measuring the displacement of an upper surface plate holding member by a displacement gauge per specific rotational period of the upper surface plate or a carrier in measuring the thickness of a wafer, etc. CONSTITUTION:An article to be polished A is inserted between upper and lower surface plates 1, 2 through a carrier, and the surface plates 1, 2 and a carrier are respectively rotated in their specific directions, so that the front and back surface of the article can be polished by abrasive grains B. At this time, the carrier is rotated in the reverse direction to that of the upper and lower surface plates 1, 2. The upper and lower directional displacements of a holding member 3 for holding the upper surface plate 2 is measured through a displacement detecting rod (displacement gauge) 4, thereby the thickness of the article to be polished a is measured. This displacement output of the displacement detecting rod 4 is gradually decreased while being oscillated up and down, as polishing time passes in the measurement. Accordingly, an error generated by the deformation of the surface plate, rotational precision in the axial direction of the surface plate and the position of the carrier can be restricted to the minimum level.
