Title: Manufacture of semiconductor device
Inventor: KUMADA MAKOTO
IPC: H01L21/60
Filed: 1996-06-12
Abstract: PROBLEM TO BE SOLVED: To provide a semiconductor device manufacturing method by which the productivity of a wire bonding process can be improved by realizing wire bonding with high positional accuracy by performing pre-lead recognition by recognizing and correcting the reference positions of inner leads at bonding positions. SOLUTION: The arbitrary reference position of a lead frame carried onto a first stage 2 for pre-lead recognition is recognized with a camera 1 for recognizing pre-lead and the inner leads to the reference position are recognized. Then the lead frame is carried onto a second stage 5 and the reference position is recognized with a recognition camera 3, and thereafter, the positional data of the inner leads are read out from the recognized results of the reference position. From the coordinate data of the same reference position, thereafter, the inner leads are wire-bonded to the electrode pads of a semiconductor element with a bonding head 4 by correcting the variation (X, Y, θ) of the reference position between first and second stages 2 and 5, pitch errors of the stages (along X- and Y-axes), magnification errors of the cameras, etc.

IPC: G06V30/162
Filed: 1980-10-29
Abstract: PURPOSE:To ensure the effective use of a small number of tone wedges of quantization, by changing how to set the tone wedge according to the gradation of characters. CONSTITUTION:The width of a tone wedge is varied for quantization in accordance with the gradation of a picture when the picture output to be optically read is converted into an electric signal and then into a digital signal. For instance, converters 10a-10n are set in parallel to each other in an A/D converter and the input analog signal is supplied to each converter. At the same time, the white level input receives a division of voltasge through resistances 11a-11n and converted into a reference signal. This reference signal is applied to the other input terminal of each converter. Then a resistance 13 is varied by a transistor 12 to change the width of the tone wedge. The output of each converter is coded by an encoder 14 and turned into a quantized video output of 4 bits and 16 tone wedges.

IPC: H01J23/087
Filed: 1981-09-25
Abstract: PURPOSE:To sharply improve the production efficiency of a hollow disk-type magnet and reduce the time of incorporating the magnet in a tube by approximately 30% by dividing the magnet into two in the groove section on the diameter of its one side or both sides. CONSTITUTION:A groove section 6 is provided on the diameter of one side of a magnet. The width of the groove is some 0.5-1mm. and its depth is some one fourth to one third (of) its thickness. Since the mechanical strength of this groove section is reduced by providing the groove, the possibility of generating defective magnets is exceedingly reduced during the process of dividing the magnet two. For the second magnet structure, since the grooves, 6 are provided on the diameter on both sides of the magnet, the degree of uniformity for division is improved much more.
