Patent number: 12061422Abstract: The present disclosure generally relates to a method and apparatus for loading, processing, and unloading substrates. A processing system comprises a load/unload system coupled to a photolithography system. The load/unload system comprises a first set of tracks having a first height and a first width, and a second set of tracks having a second height and a second width different than the first height and first width. An unprocessed substrate is transferred from a lift pin loader to a chuck along the first set of tracks on a first tray while a processed substrate is transferred from the chuck to the lift pin loader along the second set of tracks on a second tray. While a first tray remains with a substrate on the chuck during processing, the load/unload system is configured to unload a processed substrate and load an unprocessed substrate on a second tray.Type: GrantFiled: January 25, 2021Date of Patent: August 13, 2024Assignee: Applied Materials, Inc.Inventors: Benjamin M.

Publication number: 20080001166Abstract: A method of fabricating semiconductor devices, such as GaN LEDs, on insulating substrates, such as sapphire. Semiconductor layers are produced on the insulating substrate using normal semiconductor processing techniques. Trenches that define the boundaries of the individual devices are then formed through the semiconductor layers and into the insulating substrate, beneficially by using inductive coupled plasma reactive ion etching. The trenches are then filled with an easily removed layer. A metal support structure is then formed on the semiconductor layers (such as by plating or by deposition) and the insulating substrate is removed. Electrical contacts, a passivation layer, and metallic pads are then added to the individual devices, and the individual devices are then diced out.Type: ApplicationFiled: September 5, 2007Publication date: January 3, 2008Inventors: Jong-Lam Lee, In-Kwon Jeong, Myung Yoo

Semiconductor layers are produced on the insulating substrate using normal techniques. Trenches that define the boundaries of the individual devices are formed through the semiconductor layers and into the insulating substrate, beneficially by inductive coupled plasma reactive ion etching. A first support structure is attached to the semiconductor layers. The hard substrate is then removed, beneficially by laser lift off. A second supporting structure, preferably conductive, is substituted for the hard substrate and the first supporting structure is removed. Individual devices are then diced, beneficially by etching through the second supporting structure. A protective photo-resist layer can protect the semiconductor layers from the attachment of the first support structure.Type: ApplicationFiled: August 2, 2006Publication date: January 25, 2007Inventor: Myung Yoo
