Title: Manufacture of semiconductor element
Inventor: KATOU TAKAAKI
IPC: H01L21/22
Filed: 1993-10-26
Abstract: PURPOSE:To form a shallow junction by forming an impurity film on the ground layer of a semiconductor element and by disturbing the atom arrangement of the boundary surface between a ground layer and the impurity film by applying ion beams and diffusing the atom of impurity film to the upper-layer part of the ground layer. CONSTITUTION:First, an n-type impurity film 12 is formed on the upper surface of a p-type Si single-crystal substrate 11 and then a range limitation film 13 is formed on the entire upper surface. Then, ion beams are applied from the upper-surface side of the range limitation film 13. At this time, ions of an element, for example gallium, with relatively neutral conductive characteristics so that it is relatively heavy to reduce the ion range distance and does not become extremely p or n type for the p-type Si single-crystal surface 11 are selected as the ions. The applied Ga ion disturbs atom arrangement near the boundary surface of the p-type Si single-crystal substrate 11 and the n-type impurity film 12. Then, the Si atom of the p-type Si single-crystal substrate 11 is diffused into the n-type impurity film 12, thus forming n-type impurity diffusion region 14.

Moreover, the latter Ti-Mn-Ag-Co-Si is the alloy furthermore reducing its m.p., flowing into a narrow joined part and obtaining high strength by a small cross-sectional area. Co and Si have effect of reducing the m.p., but they raise its hardness, therefore, the compsn. is the one suppressing the hardnesss in relation to both elements.  Moreover, the elements to be added for alloying are the ones through the consideration of biological safety, and, furthermore, they are joinable without eroding the base metal in titanium and titanium alloys in artificial joints and dental materials. Moreover, defects in casting are hard to occur therein as alloys for casting.

Abstract: PROBLEM TO BE SOLVED: To prevent high pressure refrigerant gas from invading to an oil passage in a rotary shaft, and ensure a stable operation for a long period, by arranging a specified stage difference on an auxiliary bearing part for journaling an end part of a rotary shaft and a sliding part of an end part of the rotary shaft so as to apply a part of stress in an axial direction of the rotary shaft, and then, sealing gas. SOLUTION: When a transverse scroll compressor is operated, refrigerant gas is compressed by a scroll compression element, discharged from a discharge port into a sealing container, and is discharged from a discharge pipe outside the sealing container. In this time, lubricating oil is sucked from an oil guide pipe 20 of a differential pressure type oiling part 19 arranged on an end part of a rotary shaft 7 to which a rotor of an electrically driven element is fixed, and is supplied to a sliding part bypassing an oil passage 25 in the rotary shaft 7. In this case, a step difference 21C formed on the sliding part of an auxiliary bearing part 21 abuts on a step difference 7C formed on an end part of the rotary shaft 7 through the lubricating oil.  It is thus possible to prevent high pressure refrigerant gas from invading into the oil passage 25 bypassing between the rotary shaft 7 and the auxiliary bearing 21.
