Materion Breaks Ground on IR Wafer-Level Coating Cell

Facebook X LinkedIn Email
WESTFORD, Mass., May 7, 2013 — Materion Barr Precision Optics & Thin Film Coatings announced Monday that it has begun construction on a multimillion-dollar work cell that will enhance its capability in manufacturing low-defect, infrared, wafer-level coatings in high volume for the defense and consumer electronics markets. The wafer-level coating cell, a 3000-sq-ft Class 1000 cleanroom outfitted with the latest infrared coating chambers, a 3-D photolithography deposition tool, semiconductor wet-etch and alignment processing tools and semiautomated inspection tools, is located at Materion's facility in Westford. It...Read full article

    Glossary
    astronomy
    The scientific observation of celestial radiation that has reached the vicinity of Earth, and the interpretation of these observations to determine the characteristics of the extraterrestrial bodies and phenomena that have emitted the radiation.
    detector
    1. A device designed to convert the energy of incident radiation into another form for the determination of the presence of the radiation. The device may function by electrical, photographic or visual means. 2. A device that provides an electric output that is a useful measure of the radiation that is incident on the device.
    infrared
    Infrared (IR) refers to the region of the electromagnetic spectrum with wavelengths longer than those of visible light, but shorter than those of microwaves. The infrared spectrum spans wavelengths roughly between 700 nanometers (nm) and 1 millimeter (mm). It is divided into three main subcategories: Near-infrared (NIR): Wavelengths from approximately 700 nm to 1.4 micrometers (µm). Near-infrared light is often used in telecommunications, as well as in various imaging and sensing...
    optical filter
    An optical filter is a device that selectively transmits or blocks specific wavelengths, or colors, of light. Optical filters are used to control the spectral content of light in various applications, allowing certain wavelengths to pass through while attenuating or blocking others. They play a crucial role in scientific, industrial, and consumer optical systems, influencing aspects such as color rendering, image quality, and spectral analysis. Key features and principles of optical filters...
    photolithography
    Photolithography is a key process in the manufacturing of semiconductor devices, integrated circuits, and microelectromechanical systems (MEMS). It is a photomechanical process used to transfer geometric patterns from a photomask or reticle to a photosensitive chemical photoresist on a substrate, typically a silicon wafer. The basic steps of photolithography include: Cleaning the substrate: The substrate, often a silicon wafer, is cleaned to remove any contaminants from its surface. ...
    thin film
    A thin layer of a substance deposited on an insulating base in a vacuum by a microelectronic process. Thin films are most commonly used for antireflection, achromatic beamsplitters, color filters, narrow passband filters, semitransparent mirrors, heat control filters, high reflectivity mirrors, polarizers and reflection filters.
