摘要:
A method for producing a welded resin material contains steps of: superimposing a resin member having transmissibility to laser light and a resin member having absorptivity to laser light to form a contact part where the resin members are in contact with each other; forming a closed space that is adjacent to the contact part and faces one end of the contact part; and radiating the laser light from the resin member having transmissibility while pressing the resin members to each other through the contact part, so as to heat the contact part to melt a resin at the contact part, housing a resin excluded from the contact part through melting in the closed space, solidifying the resin melted at the contact part to weld the resin members.

A semiconductor pressure sensor is intended to achieve reduction in size and cost by decreasing the number of terminals and the number of pads. In the semiconductor pressure sensor, in a first mode in which correction data is input to a memory, a voltage input change-over switch and an input/output change-over switch are operated by an input signal from a switch change-over terminal in such a manner that a voltage input terminal and an input/output terminal are connected to a digital circuit, whereas in a second mode in which an electric signal corrected and amplified is output, the voltage input change-over switch is connected to a semiconductor sensor chip by means of an input signal from the switch change-over terminal, and the input/output terminal is connected to a correction and amplification circuit.

A semiconductor pressure sensor can simplify conveyance equipment on a production line, improve production operation efficiency to a substantial extent, and reduce the production cost. The semiconductor pressure sensor includes a semiconductor sensor chip for detecting pressure, a processing circuit for correcting and amplifying an electric signal from the semiconductor sensor chip, a sub package having a terminal electrically connected to the semiconductor sensor chip and the processing circuit through bonding wires, and a housing integrally formed with the sub package at an outer side thereof by insert molding. The sub package is formed with a mounting surface on which the semiconductor sensor chip and the processing circuit are mounted.
