    Abstract: A Zr-doped (Ba,Sr)TiO3 perovskite crystal material dielectric thin film. Such dielectric thin film is characterized by at least one of the characteristics including: (a) a breakdown strength of at least 1.3 MV/cm; (b) a leakage current of not more than 1x10-3 A/cm2 under applied voltage of about ±3V or above and at temperature of about 100° C. or above; and (c) an energy storage density of at least 15 J/cc. The dielectric thin film comprises zirconium dopant in the amount of 0.5% to 50% by total weight of the Zr-doped (Ba,Sr)TiO3 perovskite crystal material, preferably 2-15%, more preferably 4% to 14%, and most preferably 5% to 12%. Such dielectric thin film in a preferred aspect is deposited by a MOCVD process using metal precursors Ba(thd)2-polyamine, Sr(thd)2-polyamine, Zr(thd)4, and Ti(OiPr)2(thd)2 at a deposition temperature in the range from about 560° C. to 700° C.

    Abstract: A windowed chamber, e.g., a semiconductor manufacturing process chamber such as a scrubber, deposition chamber, thermal reactor, or the like, including a port with a radiation-transmissive window therein. Interiorly disposed within the chamber is (i) a disposable film on an interior surface of the window and/or (ii) a colorimetric medium disposed in viewable relationship to the window, so that a colorimetric change is perceivable through the window, e.g., visually or by optical sensing device, when the colorimetric medium is exposed to target gas species. Also disclosed is a gas detection article including a polymeric material that is colorimetrically responsive to the presence of at least one target gas species, in exposure thereto.

    Abstract: A gas detector (54) and process for detecting a fluorine-containing species in a gas containing same, e.g., an effluent of a semiconductor processing tool undergoing etch cleaning with HF, NF3, etc. The detector in a preferred structural arrangement employs a microelectromechanical system (MEMS)-based device structure and/or a free-standing metal element (8) that functions as a sensing component and optionally as a heat source when elevated temperature sensing is required. The free-standing metal element can be fabricated directly onto a standard chip carrier/device package (6) so that the package becomes a platform of the detector.
