Title: Gold alloy wire for bonding semiconductor device
Inventor: MURAI HIROSHI
IPC: H01B1/02
Filed: 1997-03-28
Abstract: PROBLEM TO BE SOLVED: To protect a gold alloy wire against disconnection, even if a semiconductor device is exposed to an environment of severe heat cycles by a method, wherein the gold alloy wire is formed of material composed of a prescribed amount of Ag, a prescribed amount of an element selected out of Pd and Pt, a prescribed amount of an element selected from among Y, La, Ru, Ir, Eu, Yb, Gd, and Be, and gold and unavoidable impuritiess as the rest. SOLUTION: A prescribed amount of Ag, a prescribed amount of an element selected from among Pd and Pt, a prescribed amount of an element selected out of Y, La, Ru, Ir, Eu, Yb, Gd, and Be are added to high-purity gold of purity 99.999 wt%, which are melted in a vacuum melting furnace and then cast into a gold alloy ingot. The gold alloy ingot is subjected to cold working by the use of a fluted roll and a wire drawing machine and then undergoes both intermediate and final annealing, whereby a gold alloy wire is manufactured. By this setup, even if a semiconductor device provided with a copper alloy lead frame is exposed to an environment of severe heat cycles, a gold alloy wire of this constitution can be protected against disconnection.

Abstract: PURPOSE:To increase the power efficiency of the amplifier. CONSTITUTION:An amplifier 12 amplifying input signals drives push-pull connected transistors 14 and 16, applying the requried amount of current to a load 20. A comparator 34 compares the output signal with the collector signal of the transistor 14. When a comparator 32 compares it with the triangular wave, the PWM control of the switching transistor 22 can be performed. In short, the transistor 22, diode 26 and coil 24 are used as switching regulators, improving the power efficiency of the transistors 14. With a boot strap type capacitor 60, the operational point of the switching transistor 22 can be made high potential, resulting in decreasing the voltage drop of the transistor and improving the power efficiency of the entire unit.
