  • Publication number: 20180086305
    Abstract: A steering lock device includes a position detector that detects a position of a lock member. The position detector includes a first unlock detecting portion of a digital output type that detects that the lock member is located in an unlock position and a second unlock detecting portion of an analog output type that detects that the lock member is located in an intermediate position, which is between a lock position and the unlock position. A position determination portion determines whether or not the lock member is located in the unlock position based on a detection signal of the first unlock detecting portion and a detection signal of the second unlock detecting portion, which has a parabolic output waveform that changes in accordance with movement of the lock member.

  • Patent number: 9899348
    Abstract: A wire bonding apparatus includes: a bonding tool 40 into and through a wire 42 passes; a control unit 80 that performs a movement process of the bonding tool 40 for cutting the wire 42 after forming a wire loop 90 between first and second bonding points of a bonding target 100; and a monitoring unit 70 that supplies a predetermined electric signal between the wire 42 through the bonding tool 40 and the bonding target 100, and monitors whether the wire 42 is cut or not based on an output of the supplied electric signal. The control unit 80 continues the movement process of the bonding tool 40 while the wire 42 is determined not to be cut, and stops the movement process of the bonding tool 40 when the wire 42 is determined to be cut, based on a monitoring result from the monitoring unit 70. This can shorten the operation time of the wire bonding, and improve the process efficiency of the wire bonding.

  • Patent number: 9887174
    Abstract: A semiconductor device manufacturing method includes: raising and moving a bonding tool, while paying out a wire, in a direction from a second toward a first bonding point to form in the wire a cut portion bent in a vicinity of the second bonding point; lowering and moving a tip of the bonding tool to the cut portion; lowering the bonding tool vertically to thin the cut portion; raising the bonding tool while paying out the wire; and moving the bonding tool in a direction away from the first and second bonding points and along a wire direction connecting the first and second bonding points and then cutting the wire at the cut portion to form a wire tail.

  • Patent number: 9379086
    Abstract: A semiconductor device includes a common wire that sequentially connects three or more pads; bonding portions at which a side surface of the wire is bonded to the pads; and looping portions looped from the bonding portions onto the other pads adjacent to the pads, the bonding portions and the looping portions are formed alternately. When the pads are recessed from the surface of semiconductor chips, the common wire is crushed to a thickness greater than the recess depth of the pads to be made into a flat shape. Thus, on the semiconductor device, wire connection is performed with a smaller bonding count while reducing damage to the semiconductor chips, and at the same time bonding is performed efficiently to the electrodes recessed from the surface of the semiconductor chips.
