Abstract: PURPOSE:To improve the performance of a bipolar transistor while reducing the size of the element by forming an emitter region by an impurity diffusion from a conductive layer as an emitter electrode shaped to one part on a semiconductor region as a base region while introducing an impurity in high concentration to an external base region section while using the conductive layer as a mask. CONSTITUTION:In a process in which a bipolar transistor and a MISFET are shaped onto the same semiconductor substrate, a gate electrode for the MISFET is formed while an emitter electrode is shaped, and an emitter region is formed through the diffusion of an N-type impurity from the emitter electrode while a P-type impurity is introduced to an external base region at the same time as ion implantation for shaping source-drain regions in the P channel type MISFET as employing the emitter electrode as an ion implanting mask. Accordingly, the emitter region and the external base region can be shaped in a self- alignment manner, thus lowering the resistance of the external base region and improving the performance of the bipolar transistor while reducing the size of an element for the bipolar transistor, then enhancing the degree of integration.

Filed: 1995-01-31
Abstract: PURPOSE: To improve the waterproofing property with a simple structure, and effectively take an electrostatic countermeasure by pressing the center part of a switch plate toward a membrane base by the magnetic force repulsion of the magnet of an operation part with the switch plate. CONSTITUTION: An operation part 16 has a magnet 17 exposed to the lose surface, and the magnet 17 is magnetized in such a manner that the center part of a switch plate 14 is pushed downward by the magnetic force repulsion of the magnet 17 with the plate 14 when the part 16 is set above the plate 14. When the part 16 is moved horizontally along the upper surface of a housing 15 by the finger of a hand to set the part 16 above the plate 14, the magnetic force repulsion is generated by the interaction of the magnetic flux of the magnet 17 of the part 16 with the magnetic flux of the plate 14. The center part of the plate 14 is thus elastically deformed downward, the center part of the plate 14 makes contact with a center contact 12 on the surface of a membrane base 11, and a peripheral contact 13 is electrically connected to the central contact 12 through the plate 14.  Thus, excellent waterproofing property can be provided, and an effective electrostatic countermeasure can be taken.
