  • Patent number: 11960707
    Abstract: An electronic device provides, to a display, data to present a user interface that includes a plurality of user interface objects, and a current focus on a first user interface object. While the display is presenting the user interface, the electronic device receives an input that corresponds to a movement of a contact across on a touch-sensitive surface. The electronic device, in response to receiving the input and in accordance with a determination that a first axis is a dominant axis, moves the current focus along the first axis by a first amount and along the second axis by a second amount. The amount of movement of the current focus along the second axis is reduced to a first non-zero amount by a scaling factor that is based on one or more inputs received prior to receiving the input.

  • Patent number: 11927482
    Abstract: One or more embodiments described herein generally relate to systems and methods for calibrating an optical emission spectrometer (OES) used for processing semiconductor substrates. In embodiments herein, a light fixture is mounted to a plate within a process chamber. A light source is positioned within the light fixture such that it provides an optical path that projects directly at a window through which the OES looks into the process chamber for its reading. When the light source is on, the OES measures the optical intensity of radiation from the light source. To calibrate the OES, the optical intensity of the light source is compared at two separate times when the light source is on. If the optical intensity of radiation at the first time is different than the optical intensity of radiation at the second time, the OES is modified.

  • Publication number: 20230057432
    Abstract: Embodiments of the present disclosure include methods and apparatuses utilized to reduce particle generation within a processing chamber. In one or more embodiments, a lid for a substrate processing chamber is provided and includes a cover member, a central opening, and a trench. An inner profile of the central opening contains a first section having a first diameter, a second section having a second diameter, and a third section having a third diameter. The second section is disposed between and connected to the first section and the third section. The first diameter gradually increases from the second section toward the surface of the cover member, the second diameter cylindrically extends from the first section to the third section, and the third diameter is less than the second diameter. The trench surrounds the central opening and is formed along a closed path in the surface of the cover member.

  • Patent number: 11581408
    Abstract: Embodiments of the disclosure provide an improved apparatus and methods for nitridation of stacks of materials. In one embodiment, a method for processing a substrate in a processing region of a process chamber is provided. The method includes generating and flowing plasma species from a remote plasma source to a delivery member having a longitudinal passageway, flowing plasma species from the longitudinal passageway to an inlet port formed in a sidewall of the process chamber, wherein the plasma species are flowed at an angle into the inlet port to promote collision of ions or reaction of ions with electrons or charged particles in the plasma species such that ions are substantially eliminated from the plasma species before entering the processing region of the process chamber, and selectively incorporating atomic radicals from the plasma species in silicon or polysilicon regions of the substrate.
