Patent number: 6531326Abstract: A method for calibrating the wafer transfer system by using an inspection control wafer after plasma etching is described. An inspection control wafer is provided comprising a polysilicon layer overlying an oxide layer on the surface of a semiconductor substrate wherein the polysilicon layer does not cover the oxide layer for a first distance from the edge of the wafer. The inspection control wafer is entered into the wafer transfer system wherein the wafer is transferred to a spin-on-glass etchback chamber wherein the wafer is held by clamps which extend a second distance from the edge of the wafer and wherein there is designed an overlap difference between the first and second distances. The wafer is subjected to a spin-on-glass etchback step and then inspected for damage to the oxide layer. Oxide layer damage occurs if the second distance is less than the first distance by more than the overlap difference. Oxide layer damage indicates the need to recalibrate the wafer transfer system.Type: GrantFiled: September 20, 2001Date of Patent: March 11, 2003Assignee: Taiwan Semiconductor Manufacturing CompanyInventors: Ching-Ming Chen, Yuh-Da Fan, Pao-Ling Kuo

Patent number: 5917699Abstract: A heat-radiating device including a heat-radiator and a heat conductive rod for contacting with a heat source. The heat-radiator is composed of a heat conductive pipe body integrally formed by extrusion, a heat conductive column co-axially extending in the heat conductive pipe body and multiple heat-radiating vanes radially arranged between an outer periphery of the heat conductive column and an inner periphery of the heat conductive pipe body.
