Abstract: PURPOSE: A fastening structure of an engine component bracket for a vehicle is provided to prevent the leakage of oil by inserting a bush into a hole of a bracket, attaching the bush to a boss of an oil pan and tightening a bolt through the bush along a thread in the boss. CONSTITUTION: Connecting structure of an engine component bracket consists of a bush(7) forcibly fit to a through hole(14) of an engine component bracket(3) and a boss(5) fixed by a bolt(4) protruded to one side of an oil pan(2). A second spring(8b) is inserted into the bush to be forcibly fit to the through hole of the engine component bracket. At the same time, the end of a protrusion(15) of the bush is in contact with a contact face(9) of the boss. Then, a first spring(8a) is inserted into the rear of the bush again. The first spring is connected to a nut(12) of a groove(13) of the boss via the through hole of the bush by the bolt. The first spring and the second spring absorb the vibration of the engine component bracket as the engine component bracket is connected. Therefore, the leakage of oil caused by vibration is prevented.

Abstract: PURPOSE: A method of manufacturing a semiconductor device is to decrease the speed of thermal-diffusion of phosphor by growing a polysilicon layer, thereby improving the dynamic characteristic of the semiconductor device. CONSTITUTION: A mask insulating film pattern, a gate electrode and a gate insulating pattern are formed on a semiconductor substrate(12). By etching the first insulating layer, the first insulating layer spacer(22) is formed. The thickness of the first insulating layer is from about 300 to 800 angstroms. In a cell region, impurities are implanted into the first insulating layer spacer. After etching the second insulating layer, the second insulating layer pattern(26) is formed only on a peripheral circuit area. By using a selective epitaxial growth, a single crystalline silicon layer pattern is formed on the exposed semiconductor substrate. Because the impurities are of high-density and slow in speed, the depth in a connected area is shallowly formed.
