Title: Method of welding solid copper piece
Inventor: JIYANNPOORU FUABURUUTEISO
IPC: B23K11/14
Filed: 1992-05-18
Abstract: PURPOSE: To enable welding solid copper pieces through a simple process without using filler metal by passing a current between a first and a second electrodes and heating both the copper pieces, and compressing both the copper pieces by applying pressure so that both the projects are not crushed by the first and/or the second electrode(s) to give rise to melt-stuck. CONSTITUTION: Welding is executed by a resistance welding press so that heating of two copper pieces 14, 16 is limited to their projects 15, 17. In this way, by the heating localized on a region of projects 15, 17, the copper pieces 14, 16 which are deformed and flattened by the pressure of the welding press 10 are fused and both of them are joined. Thus, welding of these two pieces 14, 16 is achieved in this way without using filler metal and without being accompanied with annealing of copper or change of color. No filler metal is applied, so the pieces are prevent from adhesion of carbon or adhesion of other impurities which give effect on the quality due to electric contact with other part.

Title: Semiconductor device
Inventor: MATSUURA TATSUO
IPC: H01L29/43
Filed: 1989-05-18
Abstract: PURPOSE:To obtain a semiconductor device of high reliability by a method wherein a bump substratum electrode structure of e semiconductor pellet is constituted of a laminated body of Ti, Ni and Ag. CONSTITUTION:A bump substratum electrode structure of a semiconductor pellet 20 is constituted of the following: a Ti layer 22, in a thickness of 100 to 500Angstrom , which comes into contact with the surface of a pellet main body 21 composed of silicon; an Ni layer 23 in a thickness of 1000 to 2000Angstrom ; an Ag layer 24 in a thickness of 3000 to 5000Angstrom . An Ag bump electrode 25 is formed in a height of 50 to 60mum on a vapor-deposited layer of three layers. As a thickness of the Ti layer 22 as a lower layer becomes thin, a VF (forward voltage) is lowered. When, however, it is made so thin, a thickness of a low-resistance layer of TiSix becomes insufficient and the VF becomes irregular. As a film thickness of the Ni layer 23 as an intermediate layer is made thick, an exfoliation defect is increased when a patterning operation of the vapor-deposited layer in a bump-plating growth face is executed by a method where a resist 9 is laid in between and an inessential part is exfoliated. In addition, as a thickness of the Ag layer an upper layer becomes thick, its exfoliation property is deteriorated in the same manner as the Ni layer 23; when it becomes thin, it is not possible to protect the Ni layer 23 during a plating operation.

Abstract: PURPOSE:To contrive a flattening of the interface of a spacer layer and a reduction in an impurity, which is mixed in an AlAs layer, by a method wherein a GaAs channel layer is grown on a GaAs substrate, the surface of the channel layer is flattened as this substrate temperature is held and after an Al irradiation of the amount of one AlAs atomic layer, the substrate temperature is heated up to a temperature, at which a mixture of the impurity is inhibited in the case of growth of the AlAs layer, while As irradiation is performed and the spacer layer is grown. CONSTITUTION:A GaAs layer 2 is grown at a first substrate temperature by a molecular beam epitaxy method (an MBE method) and thereafter, if As irradiation only is continued and the substrate temperature is held, the growth or the layer 2 is stopped, the layer 2 is annealed in a state that the evaporation of As is inhibited and the surface of the layer 2 is flattened at the level of an atomic layer. On the other hand, in case an AlAs layer is grown by an MBE method, a mixture of an impurity can be inhibited by setting the substrate temperature at a second substrate temperature higher than the first substrate temperature. Both of these substrate temperatures are combined, an Al irradiation or the amount of one AlAs atomic layer is performed at the time or heat-up from the first substrate temperature to the second substrate temperature, an AlAS layer 3b of one atomic layer is formed on the layer 2 in the initial stage of the heat-up and the evaporation of As in a way to heat-up is inhibited combined with As irradiation. Thereby, a flattening of the interface of a spacer layer and a reduction in an impurity, which is mixed in the AlAs layer, are contrived.
