Class 10 Lithography Démo Lab: Recently opened Qass 10 démonstration laboratory will enable semiconductor manufacturers to "test run" lithography tools and methods, obtaining full image wafer pattem transfers while they wait. Manufacturers will be able to test a variety of lithography options in a real-time production environment, including linked and mix-and-match methods. Applications engineers will work with customers to process and pattern wafers to customer requirements. The 3,000 ft2 lab with 1,000 ft2 of Qass 10 space includes projection steppers from Ultratech Stepper and GCA, track interface equipment from SSI, Drytek etchers, and full metrology capabilities. Ultratech Stepper, 3230 Scott Blvd., Santa Clara, CA 95054; (408) 727-4930; outside California (800) 222-1213.
FT-IR Sampling Accessories: Informative 28-page handbook describes the Leading Edge product Une, the company's highest performance sampling accessories for FTIR spectroscopy, and contains ordering data keyed to spectrometers from major manufacturers. The handbook also provides information on FT-IR sampling techniques and how they are implemented. Discussed are the théories behind such methods as ATR, diffuse réflectance, external réflectance, specular réflectance, and continuously variable ATR spectroscopy. Extensive tables and illustrations convey technical information at a glance, including a rundown of the properties of ATR crystal materials and the graphie différence between specular and diffuse réflectance.
