  • Publication number: 20260096388
    Abstract: A process condition measurement device may include a substrate and a cover. The cover may cover the substrate to protect sensors and interconnects from a process environment, such as from corrosive gases, plasma, and radio frequency signals. The cover may uncover portions of the substrate to improve the thermo-mechanical behavior of the substrate. The cover may uncover portions of the substrate by blank-through holes which are offset from the sensors and interconnects. The cover may also uncover portions of the substrate by grooves formed through the cover. The process condition measurement device may also include a thin-film which is formed over the interconnects. The thin-film may protect interconnects from the process environment. The blank-through holes, the grooves, and the thin-films may be used separately or in combination.

  • Patent number: 10796969
    Abstract: A system and method are provided for fabricating semiconductor wafer features with controlled dimensions. In use, a top surface of a semiconductor wafer is identified. A first portion of the top surface of the semiconductor wafer is then vertically etched to form a step down from a second portion of the top surface of the semiconductor wafer, the step comprised of a horizontal face and a vertical sidewall. Additionally, a film is uniformly deposited across the horizontal face and the vertical sidewall of the step. Further, the second portion of the top surface of the semiconductor wafer is vertically etched to expose, as a feature of the semiconductor wafer, the film deposited across the vertical sidewall of the step.

  • Publication number: 20200135519
    Abstract: A first nominally flat object is obtained that has a controlled warpage that has been measured in a manner traceable through a standard reference material to a fundamental unit of measurement. A measurement tool is calibrated using the first nominally flat object. After calibrating the measurement tool using the first nominally flat object, the warpage of a plurality of nominally flat objects is measured using the measurement tool, wherein the plurality of nominally flat objects is distinct from the first nominally flat object.
