Title: Automatic level control amplifier
Inventor: NISHIMURA AKIRA
IPC: H03G3/30
Filed: 1988-04-19
Abstract: PURPOSE:To prevent variation of a relative alarm detecting level from its initially set state even when the transmitting output level is reset by providing a level changing means which changes the output level of a detector between the detector and an automatic level controller. CONSTITUTION:When the level changing means 3 is provided between the detector 13 and automatic level control circuit 14, the gain distribution from the output side to the input side of the circuit 14 can be changed and the output level of the detector 13 can be reset without affecting the relative alarm detecting level. Namely, the automatic level control loop constituted of a variable attenuator 11, an amplifier 12, the detector 13, the level changing means 3, and the automatic level control circuit 14 is controlled so that the DC output level of the level changing means 3 can become constant. Moreover, an alarm detecting level is maintained at a fixed level by means of the automatic level controlling loop. Therefore, the relative alarm detecting level does not change from its initially set state even it the setting level of the output is changed.

Title: Abrasive material and polishing method and device using the same
Inventor: ITO HIDEFUMI
IPC: B24B37/12
Filed: 1996-04-18
Abstract: PROBLEM TO BE SOLVED: To surely prevent the scratching of a semiconductor wafer caused by the intrusion of foreign objects in chemical machine polishing. SOLUTION: In addition to abrasive particles 9 as main components for an abrasive material KZ, resin particles 10 such as a polyurethane resin are mixed into the abrasive material KZ used for chemical machine polishing. When the intrusion of a foreign object 11 occurs during polishing, the foreign object 11 is moved into a gap produced by the resin particles 10 and prevented from being brought into contact with the main surface of a semiconductor wafer W, and thus scratching is prevented. Since the abrasive particles 9 are smaller than the resin particles 10 and the foreign object 11 and light in weight, the abrasive particles 9 are moved to the upper side of the resin particles 10 and compressed by the resin particles 10 and the semiconductor wafer W and thereby polishing is performed.  Also, since the resin particles 10 are accumulated on a polishing pad 3 during polishing and the pad 3 contacted with the semiconductor wafer W is always kept to be an activated surface, sharpening is made unnecessary.
