Patent number: 7199383Abstract: A method for reducing particles during ion implantation is provided. The method involves the use of an improved Faraday flag including a beam plate having thereon a beam striking zone comprising a recessed trench pattern on which the ion beam scans to and fro. An ion beam selected from the mass analyzer is blocked by the Faraday flag in a closed position between the mass analyzer and the semiconductor wafer. A beam current of the ion beam impinging on the beam striking zone of the beam plate is measured. After the beam current measurement, the Faraday flag is removed such that the ion beam impinges on the semiconductor wafer.Type: GrantFiled: August 25, 2005Date of Patent: April 3, 2007Assignee: United Microelectronics Corp.Inventors: Jui-Fang Chen, Cheng-Hung Chang, Chung-Shih Shen, Chung-Jung Chen

Patent number: 7090350Abstract: An optical projection system can receive a red light beam, green light beam, and blue light beam. The optical projection system includes a color-combination prism, and the light beams respectively enter the color-combination prism from three surfaces and are combined into a mixed light beam, which exits from another surface. A projection lens set receives the mixed light beam to perform the projection. Each of the light beams further includes a liquid crystal reflection panel and a wire grid polarizer (WGP). The liquid crystal reflection panel is parallel to the corresponding surfaces of the color-combination prism. In the design, before the light beam entering the color-combination prism, they are first reflected by the WGP onto the liquid crystal reflection panel, and the liquid crystal reflection panels respectively with a polarizing state reflect the light beams, passing through the WGP and directly propagating toward the color-combination prism.Type: GrantFiled: February 18, 2004Date of Patent: August 15, 2006Assignee: United Microelectronic Corp.Inventors: Ho Lu, Chung-Jung Chen, Shih-Po Yeh

Patent number: 7086738Abstract: An optical projection system has a parallel light source for producing a parallel light beam. A first color splitter splits the parallel light beam into a first color beam and a color mixing beam. The color mixing beam includes a second color beam and a third color beam. A first both-side telecentric group is disposed on a first light path of the first color beam, so as to transform into a first light beam. A second both-side telecentric group is disposed on a second light path of the color mixing beam. A second color splitter is disposed on the second light path to split the color mixing beam into a second light beam and a third light beam. A light-combining unit receives the first, second, and third light beams and combines into a mixed beam. Then the mixed beam is projected.Type: GrantFiled: February 18, 2004Date of Patent: August 8, 2006Assignee: United Microelectronics Corp.Inventors: Ho Lu, Chung-Jung Chen, Shih-Po Yeh
