    Abstract: The implementations described herein generally relate to a sensing device for use in the semiconducting industry, which sense process parameters to control semiconductor processes. More specifically, the implementations relate to packaging for a surface acoustic wave (SAW) based devices or wireless or RF-responsive sensors for use in the harsh processing environments of a semiconductor processing chamber such that the neither the sensor and its components nor the chamber components interfere with or contaminate one another. The sensor packaging may include various packaging layers with or without protective coatings and a waveguide. The packaging may have a thickness chosen such that the thickness is less than the electromagnetic wavelength of a SAW sensor radio wave. The sensing devices may be disposed in cavities of the chamber, the processing volume, on chamber components, and/or on the substrate.

    Abstract: A method of forming a tungsten-containing layer over a substrate includes a) positioning a substrate on a substrate support in a process volume of a process chamber; b) providing a precursor gas to the process volume of the process chamber for a first duration; and c) providing a tungsten-containing gas to the process volume of the process chamber by opening a pulsing valve on a tungsten-containing gas delivery line for a second duration occurring after the first duration to form a tungsten-containing layer on the substrate. The tungsten-containing gas delivery line includes a first section connected to an inlet of the pulsing valve and a second section connected to an outlet of the pulsing valve, the first section connects the inlet of the pulsing valve to a reservoir of tungsten-containing gas, the second section connects the outlet of the pulsing valve to an inlet of the process chamber.

    Abstract: Embodiments for processing a substrate are provided and include a method of trimming photoresist to provide photoresist profiles with smooth sidewall surfaces and to tune critical dimensions (CD) for the patterned features and/or a subsequently deposited dielectric layer. The method can include depositing a sacrificial structure layer on the substrate, depositing a photoresist on the sacrificial structure layer, and patterning the photoresist to produce a crude photoresist profile on the sacrificial structure layer. The method also includes trimming the photoresist with a plasma to produce a refined photoresist profile covering a first portion of the sacrificial structure layer while a second portion of the sacrificial structure layer is exposed, etching the second portion of the sacrificial structure layer to form patterned features disposed on the substrate, and depositing a dielectric layer on the patterned features.

    Abstract: In one aspect, an apparatus includes a chamber body, a blocker plate for delivering process gases into a gas mixing volume, and a face plate having holes through which the mixed gas is distributed to a substrate. In another aspect, the face plate may include a first region with a recess relative to a second region. In another aspect, the blocker plate may include a plurality of regions, each region having different hole patterns/geometries and/or flow profiles. In another aspect, the apparatus may include a radiation shield disposed below a bottom of the substrate support. A shaft or stem of the substrate support includes holes at an upper end thereof near the substrate support.
