• Evolution and Revolution of Cerium Oxide Slurries in CMP (.pdf)
  by this. stage, mainly for the finishing step in STI CMP, wherever increasing performance and defectivity. were required, but these were only used in small volumes. Ceria slurries have the capability of. achieving higher removal rates than silica slurries and can more easily be controlled by additives...

• Development and Mechanisms of Action of a Ceria-Based Slurry for Shallow Trench Isolation CMP (.pdf)
  of have therefore been removed from the process altogether3. ownership. Ceria slurries are becoming dominant for sub-65nm node STI. This paper presents a viable alternative to the FA pad polishing for the finishing step, with silica slurries only being. process and describes a slurry-only process...
• The Real Impact of Selectivity on CMP Performance (.pdf)
  for sub-45nm technology, where silica slurries show a much greater. pattern dependency than the newer ceria-based slurries and have therefore been removed from the. process altogether3. Ceria slurries are becoming dominant for sub-65nm node STI polishing for. the finishing step, with silica slurries only...
• MICRO: Two Vendors Find Recipes
  shortly after finishing an interview with a publication from MIT. "One of the things that we were able to accomplish right before the downturn hit . . . is to get this company realigned around the idea of operational excellence." He admits the concept sounds corny. "This isn't corny. This is why...
• Magnesium takes on aluminum and steel
  alloys are too soft. is well known for producing near-net shapes that need little finishing molded parts have smoother surfaces than conventional castings, without flow marks. Surfaces also have lower porosity and fewer defects and, thus, better mechanical properties than die-cast magnesium...
• Polymer Coatings
  because they are effective against corrosion in thinner films than are most other finishing materials. They are often used as primers under other materials that have good barrier properties but marginal adhesive characteristics. Coating thickness can vary from 1 mil for light-duty protection to as much...

• Flooring System Meets Challenges at Vaccine Pilot Plant
  or flat trowel. A bonding coat was then applied with a roller followed by the broadcast of the paint chip blend into this material. The last step was the spray application of the seal coat. Development of the Vaccine Pilot Plant was completed in October 2005. While finishing touches and building...
• The next step in rapid prototyping
  was printed and assembled by Griffin Industries for spacing studies at an agricultural equipment manufacturer. It was printed on a Z Corp. 3D Printer and then infiltrated with Z-Max epoxy to strengthen the part for drilling and tapping. As a finishing touch, engineers treated the part with a powder-coat...
