Publication number: 20070248895Abstract: A method for reducing defect levels in a photomask by employing a cleaning process which does not degrade the photomask after multiple cycles of cleaning. The method is suitable for patterned metal stencil photomasks and phase shift photomasks. The method employs an alkaline aqueous cleaning solution for a particular time in a particular temperature range. The method results in improved photomask yield after multiple cleaning cycles.Type: ApplicationFiled: June 25, 2007Publication date: October 25, 2007Applicant: TAIWAN SEMICONDUCTOR MANUFACTURING CO., LTD.Inventor: Wei-Yu Su

Patent number: 6948619Abstract: A pod for transporting reticles is made with a reticle support that has a ?-shape and is provided with pins, whose arrangement matches the location of chrome-free areas on a reticle base. Due to that, the pins, when supporting the reticle, come into contact with the reticle in chrome-free areas thereof. Thus, scratching the metallic areas and releasing metallic particles is prevented from occurring.Type: GrantFiled: July 5, 2002Date of Patent: September 27, 2005Assignee: Taiwan Semiconductor Manufacturing Co., LTDInventors: Wei-Yu Su, Li-Kong Tern, Dong-Hsu Cheng

Patent number: 6869733Abstract: The present invention is a method of protecting reticles from electrostatic damage during their use in manufacturing lines and while patterning photoresist films on device substrates. An anti-static layer comprised of an ammonium salt is formed on both sides of a pellicle which is then attached to a metal frame that has been coated with an anti-static layer of the ammonium salt. The frame with attached pellicle is connected to a reticle by an adhesive. Any electrostatic charges that form on the surface of the anti-static layers or on the reticle are conducted into the metal frame where they are dissipated. The ammonium salt is preferably (RN4+) Cl— in which (RN4+) has the structure: where Y is an alkyl group or C6H4, m=1 to 10000, and X? is Cl?.Type: GrantFiled: September 30, 2002Date of Patent: March 22, 2005Assignee: Taiwan Semiconductor Manufacturing CompanyInventor: Wei-Yu Su
