Title: Method and device for chemical and mechanical flattening using micro duplicate surface
Inventor: MEYER STUART L
IPC: B24B37/24
Filed: 1998-06-26
Abstract: PROBLEM TO BE SOLVED: To uniformalize the flattening of the whole surface of an integrated circuit structural body by providing a polishing slurry and a micro duplicate pad having a surface for flattening the material surface. SOLUTION: Substantially acute distal points 35a of a micro duplicate structural body 33 relating in the bottom side of a pad 31 are brought in contact with a dielectric surface 18a, when a material and the pad 31 are mutually moved. Chemical and mechanical activated polishing slurry having abrasive grain 37 is fed between the adaptable surface of the material 12 and the pad 31 so as to accelerate the flattening process. When the pad 31 is moved in relation to the material 12, the distal points 35a relating to the pad 31 exhibit the chemical effects of the polishing slurry, rub the micro structural body 26 of a device, and remove a substance from the ridge. The uniformity of the micro duplicate structural body induces the attendant uniformity of the removal rate across the material.

Filed: 1984-08-31
Abstract: PURPOSE:To control surely signal transmission by forming the 2nd DC circuit and AC circuit when a call signal is applied to reduce sufficiently a signal transmission loss at the primary and secondary sides. CONSTITUTION:When a DC control voltage Vc exceeding a Zener voltage Vz is fed from a central station via a telephone line A (Vc>Vz), the Vz is turned on.
