Title: Wire bonding method
Inventor: TAKAMI SHIGENARI
IPC: H01L21/60
Filed: 1990-10-30
Abstract: PURPOSE:To enhance bondability by a method wherein, before executing a wire bonding operation, a bonding part at a lead frame or a substrate is dry- cleaned so that an organic thin film which has adhered to the surface can be removed without using a liquid. CONSTITUTION:At a wire bonding operation using Cu wires to a lead frame 4 or a substrate at a semiconductor device 1, bonding parts at the lead frame 4 or the substrate are dry-cleaned. Thereby, an organic thin film which has adhered to the surface of the lead frame 4 as a part to which the wire bonding operation is executed is removed without using a liquid. The Cu wires and the Cu lead frame 4 come into direct contact with each other. When heat or heat and ultrasonic waves are applied, they are bonded stably by the action and their bondability is enhanced. Since the liquid such as water, an organic solvent or the like is not used in order to remove the organic thin film, it is not required to control the contamination of the liquid and to replace the liquid which has been contaminated.

Filed: 1997-10-27
Abstract: PROBLEM TO BE SOLVED: To enable the adjusting of counter potentials by eyes of a human being by providing a changeover means of the case of inverting the polarity of a video signal to be inputted to respective pixel electrodes every one field and the case of inverting it every n fields ((n) is a positive integer except 1) to perform the rewriting of the video signal. SOLUTION: A polarity inversion circuit 13 is a circuit for producing positive and negative write signals and the inversion cycle of the circuit 13 is switchingly controlled by an inversion cycle control means 14. A signal being the repeat of a positive, a negative, a positive, a netagive... is rewritten into a signal being the repeat of a positive, a positive, a negative, a negative.... When counter potentials are shifted, a signal is made so as to repeat a brightness and a darkness every two fields with respect to the case the signal repeats the brightness and the darkness every one field. In short, the cycle of the brightness and the darkness can be doubled by only rewriting the signal without changing a driving speed. Thus, since flicker is made visible, the adjusting of counter potentials is made possible with the eyes of a human being.

Title: Identification and/or sensor system
Inventor: FURANTSU ZAIFUERUTO
IPC: G01S13/02
Filed: 1996-10-16
Abstract: PROBLEM TO BE SOLVED: To convert the attenuation of a resonator into a signal of a constant frequency by providing a receiver with a phase lock loop being opened/closed by a response signal, and a threshold value detector for driving a sample hold circuit in the loop. SOLUTION: An input signal from a transmission/receiving switch 3 for an identification/sensor unit is mixed 10 with a signal from a frequency synthesizer 17 and then it is detected by means of a threshold value detector 15 in order to drive a sample hold circuit 12. When a mixer output signal having sufficient S/N is present, phased lock loops 11-14 are locked thus synchronizing a voltage control oscillator 14 with an input signal within a short period. When the input signal drops below the threshold level of detector 15 or disappears, the loops 11-14 are unlocked through the circuit 12 and the oscillator 14 oscillates freely as a function of a control voltage from the circuit 12.  During the operation, the phase detector (ring mixer) 11 holes the product of amplitude of the input signal and the signal from oscillator 14 thus compensating for exponential attenuation of an input signal.

Abstract: PURPOSE:To miniaturize an element by selectively growing interconnections of first and third layers through a high melting point metal selectively grown from on the interconnection of the first layer without an interconnection of a second layer while in contact with an insulating film covering the interconnection of the second layer. CONSTITUTION:A through hole 111 is opened by etching from above an interlayer film 108 of a second layer to etch interlayer films 104, 108 except insulating films 106, 107 covering the upper surface and side face of the interconnection of the second layer. A high melting point metal 109 is selectively grown in the through hole. For example, silicon nitride is selected as the materials of the films 106, 107 to be scarcely etched as compared with the films 104, 108, and tungsten is selected as high melting point metal selectively grown in the hole. Since the hole is opened by avoiding the interconnection 105 of the second layer in a self-alignment, it is not necessary to provide a mask aligning margin and a margin for overetching between the second interconnection and the hole. Accordingly, an element can be miniaturized is compared with a conventional method.
