Abstract: PURPOSE: To avoid the relocation of impurity into the surface insulation film, by performing ion injection annealing via the direct thermal nitride film formed on the Si surface.  
     CONSTITUTION: The insulation film 2 of the P type Si substrate 1 is opened, it is processed at 900 to 1300°C under NH 3  atomosphere and Si 3 N 4  3 is selectively coated. The B ion injection layer 5 is made on the thin film 3 by taking the film 2 as a  mask. Next, processing is made at about 1000°C for about 30 minutes. In this case,  the Si 3 N 4  film 3 forms a strong mask against the diffusion of B and performs no  absorbing out as SiO 2 , then the surface concentration of the layer 5 is not lowered.  Further, the invasion of alkali ions can completely be blocked with the finness of  the nitride film itself and good masking nature. Next, rquired gate film is formed  by overlaying CVDSiO 2  and the gate electrode material of polycrystal Si7 is laminated. After that, FET is formed with conventional methods. With this, correct threshold value can be assured with channel doping.

Abstract: PURPOSE:To eliminate torque fluctuation and prevent a shock at the time of a transfer by learning and correcting a fuel injection quantity map set in response to valve operating characteristics so that the preset air-fuel ratio is obtained. CONSTITUTION:The fuel injection quantity in response to the rotating speed and load of an engine is retrieved from a fuel injection quantity map set in response to valve operating characteristics in an electronic control circuit 48, and the actual air-fuel ratio when injection is performed from an injector 46 based on it is detected by an A/F sensor 55. The correction quantity of the fuel injection quantity to obtain the preset air-fuel ratio is calculated by the comparision with the actual air-fuel ratio, and the whole fuel injection quantity map is corrected based on it. When the fuel injection quantity by the corrected map for the valve operating characteristics in use nearly coincides with that for the valve operating characteristics to be transferred, the valve operating characteristics are transferred by a variable-valve timing lift mechanism VT. The engine output torque can be invariably matched before and after the trans fer.
