Title: Device for wire bonding
Inventor: NOGUCHI KAZUYA
IPC: H01L21/60
Filed: 1982-07-12
Abstract: PURPOSE:To enable to perform a wire bonding work continuously in a stabilized and accurate manner by a method wherein one or a plurality of luminous sources, a light- receiving part where a reflected beam of light will be received, and a control part are provided respectively. CONSTITUTION:A light-emitting part 7 is fixed to the position where the beam of light radiated by the light-emitting part 9 will be spotted on the surface 5 of a pellet located directly below a bonding tool 1. The light-receiving part 8 is fixed at the position where the reflected light 10 on the pellet surface 5 of the light-emitting part 9 can received the reflected light. As the reflection factor on an electrode pad surface 6 is sufficiently larger than that of the other surface and the intensity of light received at the light-receiving part 8 can be checked, a judgment whether or not the bonding tool 1 is on the electrode pad 6 can be given easily. When the judgment is given by the control part with the bonding tool 1 positioned on the electrode pad 6 by detecting the intensity of the light received by the light-receiving part 8, a main body command signal (b) is outputted from the control part, thereby enabling to stop the bonder main body and to move a bonder head or a semiconductor pellet 5 to the position where the light received by the light-receiving part 8 will reach the highest intensity which is, in other words, the center of the electrode pad 6.

Abstract: PURPOSE:To form an inexpensive portable liquid crystal television set with low power consumption by forming an impurity layer forming the source and drain of a transistor with a gate electrode from downward of a substrate as a light mask in a gate self-aligning manner. CONSTITUTION:A gate electrode 41 is formed on a transparent substrate 40. Then, a gate insulating film 42 is formed on the electrode 41.

Abstract: PROBLEM TO BE SOLVED: To provide an LED driving circuit capable of eliminating erroneous recognition of an operator when an LED is switched at a high speed or turned on during a very short period. SOLUTION: A single shot circuit 20 receives a first LED driving signal 2-A as an input signal, and outputs a specific time as an active time after the rising is detected. The time wherein a man can recognize the turning-on of an LED 22 is defined, and the active time is set longer than the defined time. A limiter resistor 21 defines the current flowing in the LED 22. A second LED driving signal 2-B outputted from the single shot circuit 20 is an active 'L' signal. when the signal becomes active, a current flows in the LED 22, which turns on. Since the minimum turning-on time of the LED is defined, luminance of the LED 22 can be sufficiently ensured, and erroneous recognition of an operator can be eliminated.
