Electronic chemicals web site
 |
Conductive polymers, colloidal silica, and borane-based reducing agents are highlighted on this web site. The site provides information on a number of chemicals, including BAYTRON conductive polymers, which feature variable conductivity, high transparency, and high stability, and are for use in antistatic and electrostatic surface coating and capacitor manufacture; and Levasil, an aqueous colloidal dispersion of amorphous silica, for use in wafer polishing and CMP of semiconductor substrates. Site users can also e-mail technical questions, review information by application, and request free literature.

High-vacuum deposition system brochure
 |
A line of high-vacuum deposition systems are described in this brochure. Wafer applications for the systems include the coating of semiconductor materials, LEDs, MEMs, and MR/MGR heads. The Mark 50 systems also have a loadlock chamber that isolates sources from the process chamber between loading and unloading wafers. Other features include an optional PLC/PC-based control system and either ballroom or through-the-wall mounting design to satisfy cleanroom requirements. The Mark 50 can be used for both sputtering and evaporation processing, as either a dedicated or sequential tool. Moving substrates and precision process control provide across-substrate, substrate-to-substrate, and run-to-run high film uniformity.
