Abstract: Disclosed are barrier coatings for fused silica components used in semiconductor processing. In particular, the present disclosure concerns protective substrate-barrier coatings composed of corrosion-resilient metal compounds which provide superior resistance to erosion/corrosion when a coated substrate is subjected to the acidic environments at elevated temperatures typical for semiconductor processing.

Abstract: An improved temperature sensor assembly (15) comprising a temperature sensing probe (16) having a temperature sensing portion (18), a terminal portion (21), and an intermediate portion (20) between the temperature sensing portion and the terminal portion; a mounting element (28) in sliding engagement along a first axis (x-x) with the intermediate portion of the temperature sensing probe such that the temperature sensing probe is movable linearly relative to the mounting element in an axial direction; the mounting element configured to attach to an open tip thermowell (100) such that the temperature sensing portion of the probe is exposed to a process environment (104); the temperature sensing probe comprising a stop (19) configured to bear against a seat (108) in the thermowell; and a spring element (24) arranged between the stop and the mounting element and configured to bias the stop and the mounting element linearly away from each other in the axial direction.
