摘要:
A mask layer having an opening is formed on a semiconductor substrate. Next, oxygen ions and a first impurity are implanted into the semiconductor substrate using the mask layer as a mask. Then, the mask layer is removed. Next, the oxygen ions are heat treated to react and form an oxide film on the region where the first impurity has been implanted. Then, the oxide film is removed to form a depression in the semiconductor substrate. Next, a gate insulating film and a gate electrode are formed on the depression. Then a second impurity is implanted into the surface of the semiconductor substrate to form a source/drain. An impurity lighter than the oxygen ions and the second impurity is used as the first impurity.

A siamese-type cylinder block blank which is composed so that upon the pouring a molten metal under a pressure, a sleeve of cast iron is cast in each cylinder barrel of a siamese-type cylinder barrel made of an aluminum alloy and consisting of a plurality of cylinder barrels connected in series. The cylinder block blank is characterized in that each sleeve cast presents a substantially oval configuration in section with the lengthwise axis parallel to the direction of cylinder barrels arranged, as a result of the reception of the solidification shrinkage force of each cylinder barrel.

摘要:
A semiconductor device is of a PoP structure such that first electrode portions provided on a first device mounting board constituting a first semiconductor module and second electrode portions provided in a second semiconductor module are joined together by solder balls. A first insulating layer having an opening is provided on one main surface of an insulating resin layer which is a substrate, and an electrode portion, whose top portion protrudes above the top surface of the first insulating layer, is formed in the opening. A second insulating layer is provided on top of the first insulating layer in the periphery of the top portion of the first electrode portion; the second insulting layer is located slightly apart from the top portion of the first electrode portion. The first electrode portion is shaped such that the top portion is formed by a curved surface or formed by a curved surface and a plane surface smoothly connected to the curved surface.
摘要:
An electrode for a semiconductor device is formed on the mounting surface (particularly, the outer periphery thereof) of a semiconductor substrate in a semiconductor module. In order to secure a large gap between the electrodes, an insulating layer is formed on the electrode. Also formed are a plurality of bumps penetrating the insulating layer and connected to the electrode, and a rewiring pattern integrally formed with the bumps. The rewiring pattern includes a bump area and a wiring area extending contiguously with the bump area. The insulating layer is formed to have a concave upper surface in an interval between the bumps, and the wiring area of the rewiring pattern is formed to fit that upper surface. The wiring area of the rewiring pattern is formed to be depressed toward the semiconductor substrate in relation to the bump area of the rewiring pattern.
