EUV Lithography Lights Path to Next-Generation Semiconductors
Feb 1, 2002 — BERKELEY, Calif., Feb. 4 -- The first full-scale prototype machine has been completed that demonstrates critical capabilities for making computer chips using extreme ultraviolet (EUV) light, announced the consortium of industry and government...
Fast Protons Generated with Double-Layer Foil Targets
Feb 1, 2002 — Using 1-ps pulses from an Nd:glass laser, researchers have shown that double-layer thin foils containing a high atomic number front layer and a low atomic number, hydrogen-rich back layer can generate fast protons with greater energies and current...
Polymer Coating Protects Immersed Fiber Optic Oxygen Sensors
Feb 1, 2002 — Pesky protein and microorganism buildup can foul up fiber optic oxygen sensors during long-term, continuous immersion in aqueous media, leading to drift and sensor failure. But researchers have discovered that polymer coatings containing...
Quantum Dot Lasers Remain Stable
Feb 1, 2002 — Quantum dot lasers are, by nature, more thermally stable than quantum well lasers. Their confinement of a limited number of electrons and holes also limits thermal carrier distribution. Used as an active region for semiconductor lasers, quantum dots...
Dow Corning Establishes Thin Film Technology Platform
Jan 30, 2002 — MIDLAND, Mich., Jan. 30 -- Dow Corning Corp. recently launched a new program, the Thin Film Technology Platform, to identify, develop and promote new products based on thin-film materials and processes. The platform was established to support and...
Daily News Briefs
Jan 15, 2002 — Ed Segal, chairman and CEO of Metron Technology, was awarded the Third Annual Bob Graham Award by Semiconductor Equipment and Materials International (SEMI). The award honors those who carry out marketing programs that enhance customer satisfaction...
Daily News Briefs
Jan 14, 2002 — Advanced Technology Coatings Ltd., a UK manufacturer of thin-film-based optical filters and coatings, has appointed Ken Reay as a nonexecutive director on its board. Reay was previously CEO of JDS Uniphase (Bracknell, UK), formerly SDL Queensgate...
Daily News Briefs
Jan 11, 2002 — BOC Edwards made three appointments in its Electronic Materials business: Vasu Mohan was named director of operations, Fluorine, and will continue to manage BOC Edwards' NF3 plant in South Africa. Rob Limouze was named business development manager,...
Deposition Systems: Meeting the Demands
Jan 1, 2002 — The key to growing the market for vacuum deposition equipment is in meeting the demands that drive it: higher throughput, enhanced automation and more precise control of layer thickness.The focus of these demands includes dense wavelength division...
II-VI Subsidiary Wins Contract for IR Targeting Components
Jan 1, 2002 — Under a multiyear contract of about $12 million, Exotic Electro-Optics, a subsidiary of II-VI Inc., will design, develop and produce the integrated forward-looking IR targeting system shroud and corresponding navigation turret assemblies for...
