Filed: 2000-03-24
Abstract: PURPOSE: A method of a self-aligned contact is provided to improve a contact resistance between a semiconductor substrate and a conductive layer by using a deep and a shallow implantation having different implanting energy. CONSTITUTION: After forming a gate pattern(120) on a substrate(100), source and drain regions(150) are formed on the substrate. After forming a spacer(140) at both sidewalls of the gate pattern, an interlayer dielectric(160) is formed on the resultant structure. A self-aligned contact hole is formed to expose the source and the drain regions. Firstly, a deep ion-implantation is performed by implanting energy of 50- 80KeV so as to prevent a leakage current at the junction between the substrate(100) and the source/drain regions(150). After forming an undoped polysilicon(240) on the resultant structure, a shallow ion-implantation is carrier out in implanting energy of 10-30KeV in order to decrease contact resistance due to a potential barrier between the source/drain region and the undoped polysilicon(240).

Abstract: PURPOSE: An engine oil changing device using compressed air and a method thereof are provided to prevent life span reduction of an engine, to reduce noise, and to lower the contamination degree of exhaust gas by completely removing the dregs of waste engine oil and by promptly changing engine oil. CONSTITUTION: In an engine oil changing device, an air-speed controller(2) is attached to a cap(1) of an oil tank(4). Through the air-speed controller, the compressed air flowing in through an air inlet port flows into the oil tank filled with engine oil. An engine oil drain valve(5) connecting a rubber hose(6) is fitted in the lower portion of the oil tank. When waste engine oil is drained from the oil tank for oil change, compressed air is blown into the oil tank. If the compressed air is filled in the oil tank, the engine oil drain valve is opened after the connection of the rubber hose with the engine oil drain valve. Then, the waste engine oil is promptly drained. Thereafter, new engine oil is filled in the oil tank. As engine oil is changed promptly and the dregs of the waste engine oil is completely removed, the life of an engine is lengthened. Further, noise and the level of contamination of exhaust gas are reduced.
