  • MICRO: Critical Material
    Purity Semiconductor Manufacturing Applications. This standard outlines metallurgical cleanliness and material composition requirements. SEMI F19-0304, Specification for the Surface Condition of the Wetted Surfaces of Stainless Steel Components. This standard covers surface quality requirements
  • Characterizing organic impurities in semiconductor-grade hydrogen peroxide
    As the semiconductor industry moves toward the 256-Mb chip generation with 0.15-um feature sizes on 300-mm wafers, wet chemical cleaning remains essential to the removal of particles and metallic and organic impurities from the wafer surface. Since semiconductor-grade hydrogen peroxide
  • New Look At Layered Material Lends Insight To Silicon
    microelectronics remain vital to industry longer than most experts expect. It may even aid the design of other devices where one material meets another -- including medical implants. Using computer simulation, the engineers demonstrated for the first time how a previously known means of creating thin films
