Patent number: 6582617Abstract: Provided is a method of etching an etch layer using a polycarbonate layer as a mask. The method includes placing an etch structure in a reaction chamber, the etch structure including an etch layer underlying a polycarbonate layer, the polycarbonate layer having apertures. The etch layer is then etched using a low-pressure high density plasma generate at a pressure in the range of approximately 1 to 30 millitorr where the ionized particle concentration is at least 1011 ions/cm3 and where the ionized particle concentration is substantially equal throughout the volume of the reaction chamber. To increase the etch rate, the etch structure can be cooled or biased. To decrease the etch rate, an inert gas can be added to the process gas mixture used to form the plasma.Type: GrantFiled: April 29, 1999Date of Patent: June 24, 2003Assignee: Candescent Technologies CorporationInventor: Chungdee Pong

Patent number: 6392750Abstract: Scattered or/and transmitted light is employed to determine characteristics, including dimensional information, of an object (60) such as part (10) of a flat-panel display. The dimensional information includes the average diameter of openings (62) in the object, the average density of the openings, and the average thickness of a layer (64) of the object. Light-diffraction patterns are produced to determine characteristics, such as abnormalities (146 and 148), of crossing lines (140 and 142) in such an object.Type: GrantFiled: August 31, 1999Date of Patent: May 21, 2002Assignee: Candescent Technologies CorporationInventors: John E.

Patent number: 6356013Abstract: A flat panel display and a method for forming a flat panel display. In one embodiment, the flat panel display includes a wall which is held in place by a structure formed either on the faceplate or on the backplate. In one embodiment the supporting structure is formed by two adjacent walls that form a slot which mechanically restrains the wall. In another embodiment a slot is formed within the faceplate and the walls of the slot mechanically restrain the wall. In one embodiment wall segments are inserted into supporting structures that mechanically restrain each wall segment. In another embodiment a UV curable or a heat curable adhesive is used to maintain walls in their proper alignment and position. In yet another embodiment a conductive material is melted so as to bond conductive lines located on the wall and conductive lines located on the faceplate.Type: GrantFiled: September 16, 1999Date of Patent: March 12, 2002Assignee: Candescent Intellectual Property Services, Inc.Inventors: Chungdee Pong, John D.
