A free slide chart from Scott Specialty Gases identifies and links potential lost revenue to the inaccuracy of NO_x and SO₂ mixtures used to calibrate continuous emission monitors (CEMs). To avoid over- or understating emissions, the Environmental Protection Agency (EPA) requires that CEM calibration mixtures provide ±2% accuracy—in other words, the actual mixture concentration contained in a cylinder must be within 2% of the certified concentration (tag value) as stated by the manufacturer. Inaccurate CEM calibration can lead to overstating emissions, thus costing a company hundreds of thousands or even millions of dollars in lost emission credits. The slide chart is particularly valuable considering the results of an EPA audit showing that environmental calibration mixtures are frequently less accurate than indicated by some gas suppliers. It can be obtained by calling 800-21-SCOTT. Information: www.scottgas.com. (Semicon West, S.F., North Hall, Booth 6153)

Aviza Technology has been awarded a patent for a multilayer composite dielectric film concept for improving the electrical properties and thermal stability of gate dielectrics in advanced devices. The film, a composite of high-k metal oxide and metal silicate, enhances compatibility between a poly electrode and the silicon substrate at the transistor level. Although the patented concept was developed for devices with features of ≤65 nm, it can also be used at the 90-nm level. The company's atomic layer deposition products will use the new film concept, which can be sequentially deposited in situ in a single chamber. Information: www.avizatechnology.com.
