Publication number: 20240128060Abstract: Systems and methods for material processing using wafer scale waves of precisely controlled electrons in a DC plasma is presented. A surface floating potential of a substrate placed atop a stage in a positive column of the DC plasma is adjusted and maintained to a reference potential. A periodic biasing signal referenced to the reference potential is capacitively coupled to the stage to control a surface potential at the substrate according to: an active phase for provision of kinetic energy to free electrons in the DC plasma for activation of targeted bonds at the surface of the substrate; a neutralization phase for repelling of the free electrons from the surface of the substrate; and an initialization phase for restoring an initial condition of the surface floating potential.Type: ApplicationFiled: December 5, 2023Publication date: April 18, 2024Inventors: Stewart Francis Sando, Samir John Anz, David Irwin Margolese, William Andrew Goddard

Patent number: 11956335Abstract: An application mapping procedure obtains and aggregates application mapping information from a plurality of machines in a distributed system. An application dependency map, including first layer of application mapping information, is initialized, and then a first query is sent to one or more of the machines. In response, information identifying entities that have participated in predefined communications with entities identified in an existing layer of application mapping information in the application dependency map are received, and a second layer of application mapping information is added to the application dependency map, based at least in part on the information received in response to the first query. After adding the second layer of application mapping information to the application dependency map, a second query is sent to one or more of the of the endpoint machines, the second query being based at least in part on the application dependency map.Type: GrantFiled: May 23, 2022Date of Patent: April 9, 2024Assignee: Tanium Inc.Inventors: Naveen Goela, Rishi Kant, Andrew R.

Patent number: 11942306Abstract: Atomic layer etching (ALE) of a substrate using a wafer scale wave of precisely controlled electrons is presented. A volume of gaseous plasma including diluent and reactive species and electrons of a uniform steady state composition is generated in a positive column of a DC plasma proximate the substrate. A corrosion layer is formed on the substrate by adsorption of the reactive species to atoms at the surface of the substrate. The substrate is positively biased to draw electrons from the volume to the surface of the substrate and impart energy to the electrons to stimulate electron transitions in the corrosion layer species, resulting in ejection of the corrosion layer species via electron stimulation desorption (ESD). The substrate is negatively biased to repel the electrons from the surface of the substrate back to the volume, followed by a zero bias to restore the steady state composition of the volume.Type: GrantFiled: September 25, 2023Date of Patent: March 26, 2024Assignee: VELVETCH LLCInventors: Samir John Anz, David Irwin Margolese, William Andrew Goddard, Stewart Francis Sando
