Title: Semiconductor device
Inventor: FUKUSHIMA TAKETOSHI
IPC: H01L29/78
Filed: 2001-05-30
Abstract: PROBLEM TO BE SOLVED: To reduce the ON resistance of a longitudinal FET while securing its withstand voltage. SOLUTION: A semiconductor has a transistor in longitudinal trench gate structure having a high-density drain area, a low-density drain area, a channel area, and a source area formed one after another; and the bottom of a gate conductor layer is positioned in a boiled-up layer formed by diffusing impurities from the high-density drain area to the adjacent low-density drain area. Further, the density of the channel area is made less than the impurity density of the low-density drain area. The corners of a trench never reach a semiconductor base with high impurity density, so the reliability of a gate insulating film can be improved. Further, a depletion layer which restricts the withstand voltage expands more to the channel area than to the drain area and the withstand voltage is improved. An accumulation layer is formed at the part of which comes into contact with the trench-side wall of a semiconductor layer and the ON resistance is reduced.

Title: Fuel injection controller for internal combustion engine
Inventor: ATSUMI YOSHIAKI
IPC: F02D41/04
Filed: 2001-06-07
Abstract: PROBLEM TO BE SOLVED: To emit oxygen excessively absorbed in a catalyst with an oxygen absorption/emission function by a proper amount. SOLUTION: This fuel injection controller has the catalyst 22 inside an engine exhaust passage 21. The catalyst 22 absorbs excessive oxygen when oxygen in exhaust gas flowing in the catalyst 22 is excessive, and emits oxygen when the oxygen in the exhaust gas flowing in the catalyst 22 is short. Thereby, the catalyst 22 keeps oxygen concentration in internal atmosphere at prescribed concentration to purify a specific component in the exhaust gas. When the oxygen in the exhaust gas flowing in the catalyst 22 is excessive over a prescribed period, the controller makes the rich exhaust gas flow in the catalyst 22 to execute oxygen emission treatment for emitting the oxygen from the catalyst 22. The controller has a sensor capable of detecting the oxygen concentration in the exhaust gas flowing out from the catalyst 22.  By executing the oxygen emission treatment on the basis of the oxygen concentration in the exhaust gas detected by the sensor during the execution of the oxygen emission treatment, the controller controls a rich degree of the exhaust gas flowing in the catalyst 22.
