MICRO:The 300-mm Imperative, by Gary Gallagher, p.81 (July '99)
at >=0.12 um. Once again, the wafer carrier was part of a system that included a loadport and a Class 1 minienvironment. Additional particle performance testing is required so that advanced wafer carriers can meet stringent PWP roadmap requirements under normal operating conditions. To better understand...

Light as a feather -- stiff as a board
to that for making paper. Raw materials (chopped fiber-glass, polypropylene (PP), and additives) disperse as an aqueous foam in a mixing tank. From the tank, the mixture pumps onto a forming belt. A uniform fibrous web results as the slurry passes through a vacuum. The wet web goes through a dryer to remove...

No Such Thing as Too Quiet
masks, for fiberglass installers. Polymer foams. High-density polymer foam is also a widely used insulator. Foam owes its acoustic absorption efficiency to its ability to fill the cavity into which sound waves propagate. The frequencies absorbed depend on the polymer material and the foam pore size, so...
