Title: Cleavage device and method of semiconductor wafer
Inventor: HARAGUCHI FUMIAKI
IPC: B28D1/22
Filed: 1997-03-18
Abstract: PROBLEM TO BE SOLVED: To improve a cleavage scanning, reduce the manufacture of a non-conforming article, and to improve yield by picking up the image of a region for performing the cleavage of a semiconductor wafer, scanning the inside of the cleavage region in a direction for crossing a cleavage line, and performing a cleavage along the cleavage line that is obtained by detecting the information of a position where brightness changes. SOLUTION: The width direction of a wafer 1 is successively scanned in a direction for crossing an image processing region 4aa to detect a true cleavage line 1b in the image processing region 4aa. First, several lens of picture elements out of all picture elements are divided and formed into blocks to the length in side direction for each scanning line, and the digital brightness data of each picture element are added for each block to obtain the total. Each total brightness is repeatedly compared one another and a block with the lowest brightness data is used as a candidate of the cleavage line 1b.  The brightness data of a scanning line that is determined to be the detection area of the cleavage line 1b is differentiated in a scanning direction, left and right edges are detected, a line width W is calculated, and the left and right edge candidates are averaged and the center position of the cleavage line is obtained when the calculated width is close to a set width.

Title: Signal connection circuit
Inventor: ERITSUKU JIYON RANDOBAAGU
IPC: H03K17/00
Filed: 1984-04-02
Abstract: PURPOSE:To free from the effect of a base current even when a transistor is used as connection changeover switch by offsetting the base current flowing through a signal path with a compensation circuit when the transistor is ON. CONSTITUTION:When a switch 28 is closed, a Tr 18 is turned ON and the input is set to the DC connection while when the switch 28 is opened, the Tr 18 is turned OFF to set it to the AC connection. In the DC connection, current flowing through a compensation circuit of resistors 37 and 39 from the connection point 41 is set to be almost equal to the base current of the Tr 18. The base current will not flow to a feedback resistor 46 and hence, the output level of an OP amplifier 36 turns to the ground potential when no signal is given. In the AC connection, the base current will not flow while current runs through the compensation circuit. But the output signal of a terminal 50 is free from the effect of the current flowing through the compensation circuit by setting the current so that the drop in the voltage of the resistor 46 caused by the current equals the absolute value of the voltage of a non-inversion input terminal of the OP amplifier 36.
