Patent number: 11978644Abstract: A substrate processing system includes: a batch-type processing part that collectively processes a lot including substrates arranged at a first pitch; a single-substrate-type processing part that processes the substrates of the lot one by one; and an interface part that delivers the substrates between the batch-type processing part and the single-substrate-type processing part. The batch-type processing part includes a processing bath that stores a processing solution having a lump shape or a mist shape, a first holder that holds the substrates arranged at the first pitch, and a second holder that receives the substrates arranged at a second pitch from the first holder in the processing solution. The interface part includes a transfer part that transfers the substrates held separately by the first and second holders in the processing solution, from the batch-type processing part to the single-substrate-type processing part.Type: GrantFiled: August 12, 2022Date of Patent: May 7, 2024Assignee: TOKYO ELECTRON LIMITEDInventors: Kouzou Kanagawa, Kotaro Tsurusaki, Keiji Onzuka, Yoshihiro Kai

Publication number: 20240072203Abstract: A method for fabricating light emitting diode (LED) dice includes the steps of: providing a substrate, and forming a plurality of die sized semiconductor structures on the substrate. The method also includes the steps of providing a receiving plate having an elastomeric polymer layer, placing the substrate and the receiving plate in physical contact with an adhesive force applied by the elastomeric polymer layer, and performing a laser lift-off (LLO) process by directing a uniform laser beam through the substrate to the semiconductor layer at an interface with the substrate to lift off the semiconductor structures onto the elastomeric polymer layer. During the laser lift-off (LLO) process the elastomeric polymer layer functions as a shock absorber to reduce momentum transfer, and as an adhesive surface to hold the semiconductor structures in place on the receiving plate.Type: ApplicationFiled: November 6, 2023Publication date: February 29, 2024Applicants: SemiLEDs Corporation, SHIN-ETSU CHEMICAL CO., LTD.Inventors: Chen-Fu Chu, Shih-Kai Chan, Yi-Feng Shih, David Trung Doan, Trung Tri Doan, Yoshinori Ogawa, Kohei Otake, Kazunori Kondo, Keiji Ohori, Taichi Kitagawa, Nobuaki Matsumoto, Toshiyuki Ozai, Shuhei Ueda
