  • Publication number: 20110248380
    Abstract: In a manufacturing method for a semiconductor device having a coil layer part on a substrate, two support substrates each having a flat surface are prepared, and a component member is formed on the flat surface of each of the support substrates. The component member includes a wiring portion having a predetermined pattern and an insulation film surrounding the wiring portion. The wiring portion is provided with a connecting portion exposing from the insulation film. A coil layer part is formed by opposing and bonding the component members formed on the support substrates to each other while applying pressure in a condition where the flat surfaces of the support substrates are parallel to each other. A coil is formed in the coil layer part by connecting the wiring portions through the connecting portions.

  • Patent number: 7833876
    Abstract: In a manufacturing of a semiconductor device, at least one of elements is formed in each of element formation regions of a substrate having a main side and a rear side, and the substrate is thinned by polished from a rear side of the substrate, and then, multiple trenches are formed on the rear side of the substrate, so that each trench reaches the main side of the substrate. After that, an insulating material is deposited over an inner surface of each trench to form an insulating layer in the trench, so that the element formation regions are isolated. Thereby, generation of cracks and structural steps in the substrate and separation of element formation regions from the substrate can be suppressed.

  • Publication number: 20090261555
    Abstract: A suspension spring (S) and a double-rod damper (D) are installed in the interior of a front fork which comprises a body-side tube (1) and a wheel-side tube (2). The double-rod damper (D) comprises a piston (5) housed in a cylinder (3), and an upper rod (41) and a lower rod (42) connected to the piston (5). The upper rod (41) is formed to have a smaller diameter than the lower rod (42). By providing an orifice (6) which allows working oil in an upper oil chamber (R1) formed around the upper rod (41) to flow into a reservoir (R) while causing the pressure in the upper oil chamber (R1) to increase, expansion and contraction of air bubbles mixed the into working oil in the cylinder (3) is prevented, thereby improving the response of a damping force generated in the front fork.

  • Publication number: 20020017697
    Abstract: A semiconductor device including a reduced surface field strength type LDMOS transistor which can prevent the breakdown of elements at channel formation portions when a reverse voltage is applied to its drain. A P well and an N well are formed in an N-type substrate to produce a double-well structure, with a source electrode being set to be equal in electric potential to the N-type substrate. The drift region of the N well has a dopant concentration to satisfy the so-called RESURF condition, which can provide a high breakdown voltage a low ON resistance. When a reverse voltage is applied to a drain electrode, a parasitic bipolar transistor comprising the N well, the P well and the N-type substrate develops to form a current-carrying path toward a substrate, so that the element breakdown at the channel formation portions is avoidable at the application of the reverse voltage.
