Publication number: 20230064709Abstract: A transportation system of a cassette according to an embodiment of the present invention comprises a port and a system controller. The port accommodates a cassette carrying a glass substrate. The port includes a plurality of displacement sensors for sensing a position of a cassette. The system controller calculates a distortion amount of the cassette using a plurality of sensed values of the cassette and a misplaced amount of the displacement sensors to determine whether the cassette is in a normal settlement status. Therefore, the position of the cassette can be automatically taught without clamping operation of a clamping device clamping the cassette disposed in the port, so that it is possible to prevent defects of the glass substrate by removing various defect-causing factors such as particles and static electricity that may occur during a conventional clamping operation.Type: ApplicationFiled: February 2, 2022Publication date: March 2, 2023Applicant: RORZE SYSTEMS CORPORATIONInventor: Jeong Tae YUN

Publication number: 20220388782Abstract: A transportation system of a cassette comprises a port and a system controller. The port accommodates a cassette carrying a glass substrate, and the port includes displacement sensors for sensing a position of a cassette. The system controller calculates a distortion amount of the cassette using sensed values of the cassette and determines if the cassette is in a normal settlement status by comparing the distortion amount with a tolerance value. Therefore, the position of the cassette can be automatically taught without clamping operation of a clamping device clamping the cassette disposed in the port, thereby preventing defects of the glass substrate by removing various defect-causing factors such as particles and static electricity that may occur during a conventional clamping operation. In particular, quality defects of OLED can be eliminated by preventing particles and static electricity that affect product quality defects in the OLED manufacturing process.Type: ApplicationFiled: May 25, 2022Publication date: December 8, 2022Applicants: RORZE SYSTEMS CORPORATION, Samsung Display Co., Ltd.Inventors: Jeong Tae YUN, Dae Gyu CHOI, Sung Hwi KIM

Publication number: 20140342571Abstract: A wafer etching apparatus and a wafer etching method using the wafer etching apparatus, which are capable of etching Si wafer in a dry etching method, are disclosed. According to the wafer etching apparatus and the wafer etching method, the capacitively coupled plasma unit or the inductively coupled plasma unit and the remote plasma unit are included together to etch wafer in a high speed and to reduce etching operation time. Additionally, the chuck has an upper surface with roughness so that the wafer can be cooled down through a helium gas provided to the wafer through a minute space between the upper surface and the wafer. Therefore, unwanted plasma which is generated in the groove in the conventional wafer etching apparatus is prevented to prevent damage of the wafer.Type: ApplicationFiled: October 23, 2012Publication date: November 20, 2014Applicant: RORZE SYSTEMS CORPORATIONInventors: Saeng-Man Park, Seung-Bae Oh
