Patent JP-H11163061-A (JP)
Title: Prober for semiconductor wafer
Inventor: NAKADA YUJI
IPC: H01L21/66
Filed: 1997-11-27
Abstract: PROBLEM TO BE SOLVED: To perform accurate marking to a chip which is judged to be failure and to prevent the surface of an adjoining chip from stained, by using a non- contact ink jet recording for marking to the chip which is judged to be failure. SOLUTION: A chuck drive/alignment part moves a clack 5 by chip unit so that a chip which is to be inspected comes to a correct position. A judging part performs a specified inspection for each chip unit, and judging result is sent to an ink jet recording head control part. The ink jet recording head control part drives an ink jet recording head 9 only when a judging result is failure, and performs marking to the chip by ink jet. So, contamination of an adjoining chip caused by rubbing of ink sticking to the chip is eliminated. Since the size of an ink droplet 10 that flies away from the ink jet recording head 9 can be controlled, optimum marking is performed.

Title: Distortion elimination circuit
Inventor: TAJIMA YOICHI
IPC: H03M1/10
Filed: 1989-12-19
Abstract: PURPOSE:To obtain an output with smaller distortion and excellent S/N by adding the output of a distortion extraction circuit while adjusting the phase and the level to the output with distortion eliminated. CONSTITUTION:Since analog outputs appearing at output terminals of amplifiers 33, 34 are of opposite phase with each other and in nearly the same level, they are cancelled together while being subject to level adjustment by resistors 4, 5 and summed by an amplifier 6, and only a correction distortion component is extracted at the output terminal of the amplifier 6. The distortion component appearing at an output terminal 10 via the resistor 9 of a differential amplifier 35 is opposite in phase to that of a correction signal appearing at the output terminal via the resistor 8 of the amplifier 6 of the distortion extraction circuit. Thus, the distortion component at the output terminal 10 is cancelled by adjusting the correction signal by the resistor 8.
