Publication number: 20140130982Abstract: A thin film processing apparatus assembles a substrate and an auxiliary plate tightly and the substrate is coated with a thin film whereon the auxiliary plate is situated. Since the substrate or the auxiliary plate is transparent for thermal radiation, the thin film heated by thermal radiation symmetrically in thickness direction will be available. Consequentially debonding, warping and cracking of thin film are thus prevented and outgassing from thin film is eliminated as well.Type: ApplicationFiled: November 13, 2012Publication date: May 15, 2014Inventors: Chiung-Chieh Su, Sung-Cheng Hu, Chin-Horng Yau, Lin-Sheng Jin, Ming-June Lin, Meng-Chiuan Yu

Publication number: 20140033786Abstract: A method for fabricating a metallic member includes providing a pre-forging mould. The pre-forging mould comprises an upper mould and a lower mould. The lower mould defines a pre-forging chamber, and a die cavity defined in a bottom surface of the pre-forging chamber. A metallic stock is placed above the die cavity, and the upper mould is moved toward the lower mould to forge the metallic stock, thereby forming a pre-formed body comprising a forging portion and a pre-forged base; annealing the pre-formed body; providing a forging mould to forge the pre-formed body, thereby obtaining a forged-body with a forged base thinner than that of the pre-forged base. Then the forged-body is milled to a desired size, and sandblasted, thereby obtaining the metallic member.Type: ApplicationFiled: April 7, 2013Publication date: February 6, 2014Applicants: HON HAI PRECISION INDUSTRY CO., LTD., FU TAI HUA INDUSTRY (SHENZHEN) CO., LTD.Inventors: CHENG-HUNG LIN, QING-FENG HUO, YI-MING YOU, LIN-SHENG ZHAO, KE ZHOU, WEN-TAO WANG, MING ZHENG, TAO-MIN LIU
