Publication number: 20230369056Abstract: Embodiments of the present disclosure relates to a wet bench processing including an in-situ pre-treatment prior to performing the first set of wet bench operations. The pre-treatment may include a pre-clean operation and/or a pre-heat operation. The pre-treatment may be performed in one of the existing ONB tanks without requiring adding new tanks to an existing wet bench tool. The pre-clean operation removes particles from a batch of wafers to avoid or reduce cross-contamination and defect issues, thus improving the yield rate of the wet bench process. The pre-heat operation provides better control and stabilize the temperature in the CHB tank to stabilize the process, such as to stabilize an etch rate.Type: ApplicationFiled: May 12, 2022Publication date: November 16, 2023Inventors: Chung-Wei CHANG, Bo-Wei CHOU, Chin-Ming LIN, Ping-Jung HUANG, Pi-Chun YU, Bi-Ming YEN, Peng SHEN

Patent number: 8283638Abstract: A method for preparing an ion source from nanoparticles is provided. The method includes the steps of: providing nanoparticles, vaporizing the nanoparticles from a solid state to a gaseous state, and ionizing the gas to form the ion source. The ion source is prepared by placing solid nanoparticles in a stainless tube, heating and vaporizing the solid nanoparticles into a gaseous state, and ionizing the gas. The gas can be formed at a lower heating temperature than when solid lumps are used because solid nanoparticles have a lower melting point than solid lumps. Thus, the heating temperature is lowered, and the preparing time of the ion source is shortened. Besides, under the same temperature, an ion source prepared from nanoparticles provides higher vapor pressure and allows a higher implantation dose than when the ion source is prepared from solid lumps, thus expanding the applicability of ion implantation technology.Type: GrantFiled: September 16, 2009Date of Patent: October 9, 2012Assignee: National Central UniversityInventors: Gou-Chung Chi, Ping-Jung Huang, Chung-Wei Chen, Ching-Jen Pan, Yu-Lun Liu, Fu-Chun Tsao

Patent number: 7423970Abstract: A cross-layer rate adaptation mechanism for wireless local area network (WLAN) can obtain the channel state by calculating the Eb/N0 ratio of ACK frame transmitted from the receiver side. The mechanism determines the transmission rate of the next frame by referring to a predefined reduced mode table. When receiving an ACK frame fails, the mechanism can automatically lower the transmitting rate of the next transmission. Therefore, the method can reduce the damage to the system when ACK frame failure happens.Type: GrantFiled: October 14, 2005Date of Patent: September 9, 2008Assignee: Industrial Technology Research InstituteInventors: Li-Chun Wang, Kuang-Nan Yen, Ming-Bing Chen, Wei-Cheng Liu, Yu-Ren Yang, Ping-Jung Huang
