Patent number: 6307150Abstract: A vacuum seal suitable for use with field emission arrays is described. This seal has high reliability because the expansion coefficients of the metal and the glass are closely matched. Materials traditionally used for cathode and gate lines continue to be employed. To achieve this, a gap is introduced into each conductive line near the edges of the display. This gap is bridged by a material having an expansion coefficient that more closely matches that of the glass used for the seal and is the only material that contacts the seal. The bridge may be in the form of a deposited layer or it may be a discrete wire. A description of how the structure is manufactured is also provided.Type: GrantFiled: October 8, 1999Date of Patent: October 23, 2001Assignee: Industrial Technology Research InstituteInventors: Wen-Chun Wang, Chun-hui Tsai, Chih-Hao Tien

Patent number: 6172757Abstract: An apparatus and method are disclosed for sensing horizontally and measuring the level or tilt of features on different locations on a wafer in general, and on chip sites, in particular. This is accomplished on a conventional level sensor, modified and improved, however, according to this invention where a new electrically adjustable, two-directional zoom lens is introduced. The adjustable zoom lens provides field-by-field alignment on a stepper, by providing a variable field view and depth of focus on the viewed field. Thus, whereas prior art provides fixed field-by-field local alignment capability over fixed ship sites on a ware, the present invention extend that capability to variable field-by-field alignment over variable sites on a wafer.Type: GrantFiled: September 25, 1996Date of Patent: January 9, 2001Assignee: Vanguard International Semiconductor CorporationInventor: Hao-Tien Lee
