Abstract: PURPOSE:To improve a yield of bonding by a method wherein the respective sides of a semiconductor chip mounting part are made to have a rounding in a circular-arc shape on the side of internal electrodes and the internal electrodes are extended in a vertical direction to the outside on the peripheries of the mounting part to eliminate the phenomenon of the short-circuit between bonding wires. CONSTITUTION:The outer peripheries of a semiconductor mounting part 2 for mounting a semiconductor chip 5, particularly the central outer peripheries of the respective sides of the placing part 2 are swelled roundly toward the side of internal electrodes 1 to be led out to the outside. The electrodes 1 are extended to the outside nearly vertically to the outer peripheries of the mounting part 2. For this, the directions of bonding wires 4 for connecting semiconductor chip connection parts 3 with the electrodes 1 become nearly the same as those of the electrodes 1. Whereupon, the phenomenon of the short-circuit between a wire 4 and an electrode 1 adjacent to the electrode 1 to be connected with the wire 4 is eliminated. Thereby, a yield of bonding is improved.

Title: Liquid detector
Inventor: NAKANISHI HIROAKI
IPC: H01L31/12
Filed: 1985-05-24
Abstract: PURPOSE:To make it possible to detect from outside whether liquid exists in a vessel with a large diameter, by making the light penetrate through the vessel, and detecting the change of light path direction to discriminate whether liquid exists. CONSTITUTION:The light emitting element 8 and the photo detector 9 are fixed confronting to each other. The light axis 12 connecting the elements 8 and 10 intersects the vessel 6, and crosses the internal wall of the vessel 6 on the incidence side with some inclination. The light axis is also aligned so as to be parallel to the surface of liquid in the vessel 6. The light from the element 8 refracts at both the external and the internal surfaces of the side wall of the vessel 6. In case no liquid exists on the light axis in the vessel 6, the light travels along (a) and reaches the element 10. On the contrary, in case liquid exists on the light axis in the vessel 6, the light refracts at the internal surface of the vessel 6 on the incidence side and deviates from the light axis. Therefore the light travels along (b) and does not reach the element 10. Thus the detection signal of the element 10 changes according to whether the liquid in the vessel 6.

Filed: 1983-06-24
Abstract: PURPOSE:To synchronize external asynchronous signal and to constitute a circuit that transmits a level fixed value to an internal logical circuit in a short time by changing transistor size of P channel MOS and N channel MOS of an inverter. CONSTITUTION:When threshold value voltage of an inverter 12 is held in a line 5, output of the inverter 12 starts to move from a value near the threshold value voltage gradually to H or L. At this time, if the logical threshold value of an inverter 13 is made different from the inverter 12, output value of the inverter 13 moves to H or L in shorter time. To change the logical threshold value, the size ratio of P channel MOS17 to N channel MOS18 is changed in a CMOS inverter circuit.
