Abstract: PURPOSE: To obtain the impurity concentrations different from each other simultaneously by treating the desired areas of a compound semiconductor in a proper heat-treatment atmosphere after the said area are covered with different heat-treatment protective films or by the method wherein the protective films are selectively formed on the areas.  
     CONSTITUTION: Si ions are implanted into the semi-insulating GaAs substrate 1, Si 3 N 4  film 3 is selectively formed and the whole uppermost surface is covered with SiO 2  film 4 by the CVD method. The element is heat-treated in H 2  gas to form the n-layers 5, 6 and is meas-etched, the ohmic electrode 8 is provided to the layer 5 and the Schottky electrode 9 to the layer 6. When the Si 3 N 4  film 3 is used for a heat-treatment protective film, the impurity distribution in GaAs is similar to the one determined by the injection condition. When SiO 2  film is used, the diffusion factor of Si of the impurity is greater in GaAs, the distribution of impurity concentration is expanded from the covered part of Si 3 N 4  film. In this way, an effective impurity area can be formed by using the fact that the impurity diffusion factor in a compound semiconductor layer varies with the sort of the heat-treatment protective film.

Abstract: PURPOSE:To increase a torque and suppress a cogging torque by a method wherein a protrusion is formed on the surface of a pole whose position from the boundary between the poles is determined by a specific formula as a function of an angle defined by a formula 360 deg./(the least common multiple of the number of salient poles and the number of poles). CONSTITUTION:The cogging torque of an outer-rotor has a period thetai expressed by a formula: 360 deg./i=thetai wherein (i) denotes the least common multiple of the number of salient poles and the number of poles. If a protrusion 5 is provided on the surface of a magnetic pole 3 facing a core 1 at the position of (1/2+n)thetai from the boundary L between the N-pole and the S-pole, a cogging torque can be suppressed. Wherein, (n) denotes an integer between 0 and 360 deg./{(number of poles) Xthetai}-1. If the number of salient poles is 6 and the number of poles is 4, i=12 and theta=30 deg. and 360 deg./{4X30 deg.}-1=2 and hence n=0-2. Therefore, the salient poles 5 are formed at the positions 0 and 2 to suppress the cogging torque.
