  local roughness that may later cause problems in the photolithography step. Particles can also lead to the formation of pinholes in films deposited later. Because metallic contamination can lower an IC's breakdown voltage, copper contamination will become a growing concern on the process line as its...
• MICRO: Reducing Defects
  David E. Grosjean, Analog Devices olume MEMS fabrication involves unique yield-loss mechanisms, but its defect reduction and yield enhancement techniques are often the same as those used in the manufacture of traditional integrated circuits. As in standard IC fabs, MEMS fabs are concerned...
• MICRO:The 300-mm Imperative, by Gary Gallagher, p.81 (July '99)
  Gary Gallagher and Michael Wright, The creation of an optimal wafer environment throughout all stages of IC fabrication poses a constant challenge to the semiconductor industry. Regardless of whether this challenge has been felt at the macro level in the cleanroom or at the micro level in a process...
• MICRO: Special Apps
  steps create the circuit on the silicon substrate. Like all IC processes, this phase builds the circuit as a layered structure, with each layer requiring several iterations of material deposition, photolithography, etch, implant, and other process steps. Each step must be controlled carefully to ensure...

  and tool-installation activities. Presumably that tendency affects both mask and IC cleanrooms. Effects of AMC. To understand the effects of AMC on maskmaking applications, it is useful to review the experience of the semiconductor fabrication industry. Leading-edge IC wafer production takes place at 130 nm...
