Cryo nanomanipulator probe with integrated gas injection
A probe assembly for use with a charged particle instrument includes an elongate body having a proximal end for positioning outside of a charged particle instrument enclosed environment, a distal end for positioning within the enclosed environment and a longitudinal axis. A port interface is located on the body between the proximal and distal ends, and is coupleable to a nanomanipulator system of the charged particle instrument. A probe needle is positioned at a distal end of the body and is selectively positionable from outside the enclosed environment to contact a specimen within the enclosed environment. At least one gas injection needle is adjustably positioned near the probe needle. The gas injection needle is connectable to a source of pressurized gas to selectively inject gas in the area of the probe needle within the enclosed environment.

APPARATUS FOR SUPPLYING GAS
An apparatus for supplying gas includes: an ion chamber; and a gas supply unit connected to the ion chamber, wherein the gas supply unit includes: a case having an internal space; an inactive gas supply unit connected to the ion chamber; and a hydrogen gas supply unit installed inside or outside of the case, wherein the hydrogen gas supply unit includes: a hydrogen gas generator generating hydrogen gas; a controller connected to the hydrogen gas generator; a dehumidifying filter connected to the controller and removing moisture from the hydrogen gas; and a purifying filter connected to the dehumidifying filter and removing an impurity from the hydrogen gas, wherein the hydrogen gas generator is configured to generate the hydrogen gas through a chemical reaction between a reactant and a hydrogen-containing solid raw material.
Electron microscope sample holder fluid handling with independent pressure and flow control
A fluid metering system for gas independent pressure and flow control through an electron microscope sample holder includes: a pressure control system that supplies gas; an inlet line providing gas from the pressure control system to the sample holder; an outlet line receiving gas from the sample holder; and a variable leak valve that controls gas flow in the outlet line. The gas flows from an upstream tank of the pressure control system through the sample holder and variable leak valve to a downstream tank of the pressure control system due to the pressure difference of the two tanks as the variable leak valve meters flow in the outlet line. Flow rates are established by monitoring pressure changes at source and collection tanks of known volumes with gas independent pressure gauges. A method of directing the gas flow to a residual gas analyzer (RGA) is also presented.

Methods, systems, and apparatus for generating hydrogen radicals for processing a workpiece, such as a semiconductor workpiece, are provided. In one example implementation, a method can include generating one or more species in a plasma chamber from an inert gas by inducing a plasma in the inert gas using a plasma source; mixing hydrogen gas with the one or more species to generate one or more hydrogen radicals; and exposing the workpiece in a processing chamber to the one or more hydrogen radicals.
System and method for extending a lifetime of an ion source for molecular carbon implants
An ion source assembly and method has a source gas supply to provide a molecular carbon source gas to an ion source chamber. A source gas flow controller controls flow of the molecular carbon source gas to the ion source chamber. An excitation source excites the molecular carbon source gas to form carbon ions and radicals. An extraction electrode extracts the carbon ions from the ion source chamber, forming an ion beam. An oxidizing co-gas supply provides oxidizing co-gas to chamber. An oxidizing co-gas flow controller controls flow of the oxidizing co-gas to the chamber. The oxidizing co-gas decomposes and reacts with carbonaceous residues and atomic carbon forming carbon monoxide and carbon dioxide within the ion source chamber. A vacuum pump system removes the carbon monoxide and carbon dioxide, where deposition of atomic carbon within the ion source chamber is reduced and a lifetime of the ion source is increased.
