Sample analyzer and analyzing method thereof
The present disclosure provides a sample analyzer and an analyzing method thereof. The sample analyzer includes a first beam source configured to provide a first energy beam to a sample, a second beam source configured to provide a second energy beam, which is different from the first energy beam, to the sample, a reflected beam sensor disposed between the second beam source and the sample to detect a reflected beam of the second energy beam, which is reflected by one side of the sample, and a transmitted beam sensor disposed adjacent to the other side of the sample to detect a transmitted beam of the second energy beam.
Method for pulsed laser deposition
The invention relates to a method for pulsed laser deposition including the steps of: providing a target and a substrate facing the target; irradiating a spot on the target with a pulsed laser beam to generate a plasma plume of target material and depositing the plasma plume on the substrate; and smoothing the surface structure of the spot on the target prior to irradiating the spot with a pulsed laser beam.
ECR ion source and method for operating an ECR ion source
An ECR (Electron Cyclotron Resonance) ion source includes a plasma chamber having a circular cylindrical cross-section, magnets for generating a magnetic field for confinement of the plasma in the plasma chamber, and a microwave generator disposed outside the plasma chamber and generating at least two microwave signals. Several antennas protrude radially into the plasma chamber with a predetermined angular offset α. The antennas receive phase-shifted microwave signals from the microwave generator and radiate linearly polarized microwaves, which in turn produce a circularly polarized microwave inside the plasma chamber. A method for operating an ECR ion source is also described.

Directional treatment for multi-dimensional device processing
Embodiments of the disclosure include apparatus and methods for modifying a surface of a substrate using a surface modification process. The process of modifying a surface of a substrate generally includes the alteration of a physical or chemical property and/or redistribution of a portion of an exposed material on the surface of the substrate by use of one or more energetic particle beams while the substrate is disposed within a particle beam modification apparatus. Embodiments of the disclosure also provide a surface modification process that includes one or more pre-modification processing steps and/or one or more post-modification processing steps that are all performed within one processing system.

Power supply system
A power supply system 90 includes high frequency power supplies 92 and 93 that supply a high frequency power for plasma generation; a DC power supply 91 that supplies a DC voltage to be applied to an electrode; and control unit 94 that controls the high frequency power supplies 92 and 93 and the DC power supply 91 including a first DC power supply unit 101 that supplies a first negative DC voltage V1, a second DC power supply unit 102 that supplies a second negative DC voltage V2 having a higher absolute value than the first negative DC voltage V1, and a selecting circuit 103 that selectively connects the first DC power supply unit 101 and the second DC power supply unit 102 to the electrode; and a discharging circuit 104 connected with a node 109 between the first DC power supply unit 101 and the selecting circuit 103.
Storage and delivery of antimony-containing materials to an ion implanter
A novel method, composition and storage and delivery container for using antimony-containing dopant materials are provided. The composition is selected with sufficient vapor pressure to flow at a steady, sufficient and sustained flow rate into an arc chamber as part of an ion implant process. The antimony-containing material is represented by a non-carbon containing chemical formula, thereby reducing or eliminating the introduction of carbon-based deposits into the ion chamber. The composition is stored in a storage and delivery vessel under stable conditions, which includes a moisture-free environment that does not contain trace amounts of moisture. The storage and delivery container is specifically designed to allow delivery of high purity, vapor phase antimony-containing dopant material at a steady, sufficient and sustained flow rate.

Ion milling device and processing method using the ion milling device
This ion milling device is provided with a vacuum chamber (105), an exhaust device (101) for evacuating the interior of the vacuum chamber, a sample stage (103) for supporting a sample (102) to be irradiated inside the vacuum chamber, a heater (107) for heating the interior of the vacuum chamber, a gas source (106) for introducing into the vacuum chamber a gas serving as a heating medium, and a controller (110) for controlling the gas source, the controller controlling the gas source so that the vacuum chamber internal pressure is in a predetermined state during heating by the heater. This enables the control in a short time of the temperature for suppressing condensation, or the like, occurring at atmospheric release after cooling and ion milling a sample.
