Abstract: PURPOSE:To manufacture a bonding wire having high fracture strength and also having such a degree of hardness as to cause no damage to a semiconductor device at the time of bonding, by using high-purity copper containing a specific percentage of boron as material for bonding wire. CONSTITUTION:An alloy ingot consisting of, by weight, 0.0001-0.02% boron and the balance high-purity copper of >=99.999% purity is hot-worked and subjected to solution heat treatment, rapid cooling, and cold working to undergo age precipitation hardening so as to be formed into a bonding wire. This bonding wire has a fracture strength of 25-32kg/mm<2> and a ball hardness of 35-41 Vickers hardness. Accordingly, the condition of a loop wire can be improved to further extent. Moreover, since ball hardness is reduced as compared with the above range though ball neck strength after ball formation is high, no damage occurs to the semiconductor device at the time of bonding.

Title: Resonance-type power supply circuit
Inventor: FURUTA MASAMI
IPC: H04N3/185
Filed: 1997-09-29
Abstract: PROBLEM TO BE SOLVED: To avoid the reduction in the efficiency of a resonance-type power supply circuit and eliminate unnecessary pulses. SOLUTION: A drive power supply 3 is connected to one end of a primary coil 2 of a flyback transformer 1, and a MOSFET 4 which is a main switching device is connected to the other end. A damper diode 5 and a series circuit, consisting of a resonance capacitor 6 and a MOSFET 7 which is an auxiliary switching device are connected in parallel to the MOSFET 4. After the MOSFET 4 is turned off, a current flows back and forth between the primary coil 2 and the resonance capacitor 6. As a current which tends to flow from the primary coil 2 to the resonance capacitor 6, after the damper diode 5 has been turned on/off, is blocked by the MOSFET 7, unnecessary pulses are not generated. Further, as the zero volt of the resonance coil is applied to the MOSFET 4 when it is turned off, a switching loss can be eliminated, so that the efficiency of a circuit can be improved.
