Patent number: 6893507Abstract: Improvements in the design of a low mass wafer holder are disclosed. The improvements include the use of peripherally located, integral lips to space a wafer or other substrate above the base plate of the wafer holder. A uniform gap is thus provided between the wafer and the base plate, such as will temper rapid heat exchanges, allow gas to flow between the wafer and wafer holder during wafer pick-up, and keep the wafer holder thermally coupled with the wafer. At the same time, thermal disturbance from lip contact with the wafer is reduced. Gas flow during pick-up can be provided through radial channels in a wafer holder upper surface, or through backside gas passages. A thicker ring is provided at the wafer holder perimeter, and is provided in some embodiments as an independent piece to accommodate stresses accompanying thermal gradients. Self-centering mechanisms are provided to keep the wafer holder centered relative to a spider which is subject to differential thermal expansion.Type: GrantFiled: July 18, 2002Date of Patent: May 17, 2005Assignee: ASM America, Inc.Inventors: Matthew G.

Patent number: 6890449Abstract: A method of manufacturing a PCB comprising the steps of: forming through-holes in a substrate having releasing layers on front and back faces; filling conductive paste in the through-holes; removing the releasing layers and disposing metal foil on both faces of the substrate; and heat pressing them. A diameter of the through-holes is larger than that of corresponding holes formed on the releasing layers. According to the present invention, when the conductive paste is compressed, conductive paste protruding from the surface of the substrate is trapped at the edges of the through-holes. This configuration prevents short circuits with undesirable wiring patterns. So, an enough amount of the conductive paste can protrude from the surface of the substrate. Therefore, after the compression, stable electric connections inside the conductive paste and between the conductive paste and the metal foils are ensured, thus PCBs with superior reliability can be produced.Type: GrantFiled: June 5, 2001Date of Patent: May 10, 2005Assignee: Matsushita Electric Industrial Co., Ltd.Inventors: Eiji Kawamoto, Shigeru Yamane, Toshiaki Takenaka, Toshihiro Nishii
