  • Patent number: 8677929
    Abstract: Disclosed are methods and apparatus for masking of substrates for deposition, and subsequent lifting of the mask with deposited material. Masking materials are utilized that can be used in high temperatures and vacuum environment. The masking material has minimal outgassing once inside a vacuum chamber and withstand the temperatures during deposition process. The mask is inkjeted over the wafers and, after deposition, removed using agitation, such as ultrasonic agitation, or using laser burn off.
    Type: Grant
    Filed: December 27, 2011
    Date of Patent: March 25, 2014
    Assignee: Intevac, Inc.
    Inventors: Alexander J. Berger, Terry Bluck, Vinay Shah, Judy Huang, Karthik Janakiraman, Chau T. Nguyen, Greg Stumbo

  • Publication number: 20040020601
    Abstract: A series of modular apparatuses for processing substrates using a unique combinations of a substrate coating subsystem, a substrate curing subsystem and a PECVD-based capping subsystem. The individual subsystems are capable of being combined with one another for creating unique integrated substrate processing apparatuses that enable combined processing by the coating, curing and capping subsystems in an integrated and controlled environment, thus enabling the processing of substrates in an efficient manner, while minimizing the exposure of the substrates to an external environment and minimizing the condensation of vapors while the substrate is processed by the cure and capping subsystems.
