  • Semiconductor Case Study: ETCHING SEMICONDUCTOR WAFERS RELIES ON TIGHT TEMPERATURE CONTROL
    All semi-conductor wafers, as part of their micro-fabrication, must undergo an etching process which chemically removes layers from the surface of a wafer during manufacturing. Since the depth of these etched cavities are extremely critical, the etch rate must be precisely controlled through
  • What is Photo Etching?
    Photo etching is a process used in the creation of integrated circuits, that combines photolithography with the etching process. Photolithography is used to form patterns on semiconductor substrates coated with photoresist, resulting in selective developing of the photo-resist, when exposed
  • Semiconductor Manufacturing - Etching and Rinsing
    To divert corrosive used rinse water to either the waste treatment facility or ion exchange equipment.
  • Achieving Sub-ppb Impurity Detection to Ensure the Purity of Electronic Specialty Gases
    Electronic specialty gases (ESGs) are used throughout the electronics sector, but the largest users, with the most diverse needs are semiconductor manufacturers. Various ESGs are used in most semiconductor processes, such as film deposition, film etching, substrate doping, and chamber cleaning

    signs of a slowdown expanding to other parts of the world, " said John T. Chambers, president and chief executive. "We also now believe that this slowdown in capital spending could extend beyond two quarters. " Hynix (formerly Hyundai) mulls cut in DRAM production WASHINGTON -- Hynix Semiconductor

    Heard on the Beat (July 13) Commentary & analysis of week's chip news Applied offers deep-trench silicon etch chamber for sub-100-nm DRAM processes SANTA CLARA, Calif.--Applied Materials Inc. today announced a new silicon etch chamber for 200- and 300-mm wafer DRAM fabs needing deep-trench etching
  • Measuring the Volume of Integrated Circuit Chipping After the Dicing Process Using a Digital Microscope
    Integrated circuit (IC) manufacturing can be broken down into two processes-forming circuits on bare wafers and packaging. The circuit formation process begins with cylindrical pieces of semiconductor material. The cylinders are sliced into thin, circular pieces called bare wafers. The bare wafers
  • Metrigraphics Article in Today's Medical Developments
    their manufacturing facility and their development laboratories located in Wilmington, MA. If you need a little more precision and the parts need to be a bit smaller, the next process to move to would be chemical etching - similar to electroforming. "Chemical etching traditionally uses
