  • Passivation and the Passive Layer
    Purity of fluids and gases are a critical issue in the food and beverage industry. Passivation techniques provide a way of. achieving it.
  • Developing an Effective Passivation Process to Maintain
    from stainless steel material because of its natural corrosion. resistance and relatively chemical inert surface. However, laser marking of stainless steel alters the surface composition. and degrades the natural passive layer resulting in a mark that is susceptible to corrosion. To restore
  • MICRO: Tool/Fab Support Strategies
    experiencing excessive downtime as a result of faulty radio-frequency (RF) subsystems. Agilent uses the 590 plasma etcher from Lam Research (Fremont, CA) to etch the final nitride passivation layer. Although not a particularly demanding process, nitride passivation etch requires that the plasma tool
  • Medical Device Link .
    G. Nitsch and G. Flinn Thin films in medical technology Layers of material deposited as a coating onto a surface are used to enhance the physical and optical properties of otherwise inappropriate materials in terms of passivation, hygiene, insulation or hardness. In health-related industries, both
  • Laser Scribing Thin Silicon Nitride Films
    by simplifying cell structure, layers that perform multiple functions become attractive. SiN has been used for some years as an anti-reflective (AR) coating. Due to the recent acceptance of the passivation capability of silicon nitride films, it has become the highly favoured dielectric in silicon solar cell
  • What is Anodizing ?
    , and more friction areas. Thus, surface treatment on aluminum, or an electrolytic passivation process, is commonly used to prevent corrosions.
  • Using FIB for Wafer Lot acceptance and Design Verification
    die area of a design, FIB provides an ideal diagnostic aid. It is even now possible to perform "backside FIB", which involves milling into the die from the substrate side (as opposed to the top metal/passivation side). This allows the operator to avoid having to cut through multiple metal layers
  • Examining the corrosion resistance of chromium-passivated stainless-steel tubes
    , such as weld bead and heat-affected zones (HAZs). This results in metallic particle generation at susceptible points. Thus, corrosion-induced particles generated at the wetted surfaces of the electropolished tubes affect halogen's point-of-use purity. Recently, chromium-rich oxide passivation (CrP
