The invention presents a mass flow controller capable of supplying always stably at desired flow rate in spite of pressure fluctuations at either upstream side or downstream side of the mass flow controller. The invention is a mass flow controller having a flow rate control valve and a flow rate sensor, more specifically comprising a pressure control valve disposed at the upstream side of the flow rate control valve, a pressure sensor disposed between this pressure control valve and the flow rate control valve, and a controller for controlling the pressure control valve by feeding back the output of this pressure sensor.

A method for forming a bonding connection in a semiconductor integrated cirucit device includes a step of ion implanting a bonding pad of aluminum with silicon atoms before bonding a bonding wire to the bonding pad. The silicon atoms are introduced into the bonding pad only at its surface and its vicinity, so that the bonding pad is provided with an enhanced humidity-resistant characteristic while maintaining the overall electrical resistance of an interconnection system at a low level.

Provided are a decorative resin sheet that sufficiently brings together embossing property and embossment-retaining property, and a molded resin article on which an embossment excellent in design is formed and a method of manufacturing the molded resin article. The method of manufacturing a molded resin article includes the steps of: providing a resin sheet having a mold layer containing a polyolefin-based resin as a main component, followed by formation of an embossment on the resin sheet so that the embossment is formed on a surface of the mold layer; crosslinking the mold layer on which the embossment is formed so that a 100% modulus of the resin sheet at 200° C. becomes 0.02 MPa or more, which is measured in conformity with JIS K6251 (2004 version); placing the resultant resin sheet (10) in an injection molding die (20) so that the surface (11) of the mold layer faces a side from which a molten resin (30) is injected; injecting the molten resin (30) onto a side of the surface (11) of the mold layer in the injection molding die (20) to mold a molded resin article; and separating the molded resin article and the mold layer.

A method for manufacturing a Bi-CMOS device by preparing both of bipolar and MOS standard cells in a library is provided. A substrate of a first conductivity type is provided and a plurality of buried layers of a second conductivity type are formed on selected locations of the substrate. Then an epitaxial layer of the first conductivity type is formed on the substrate covering the buried layers. Then a plurality of wells of the second conductivity type are formed in the epitaxial layer such that each of the wells extends through the epitaxial layer from the top surface to at least a portion of the corresponding buried layer to thereby define a plurality of electrically isolated islands in the epitaxial layer. Then a bipolar transistor is formed in at least one of the islands with a MOS transistor formed in at least another of the islands.
