Abstract:
대전 입자 빔 장치(CPBD : Charged Particle Beam Device)에 통신적으로 연결된 포지셔너 제어 장치는 프로브를 챔버 내에 배치된 샘플의 접촉 포인트와 접촉시킨다. CPBD에 통신적으로 연결된 측정장치 및 포지셔너는 샘플 특징의 측정/검출을 지원할 수 있다. 제어 루틴은 CPBD, 포지셔너 및 측정 장치의 제어를 적어도 부분적으로 자동화할 수 있다. 이러한 구성요소의 하나 이상은, 적어도 하나의 프로브가 CPBD의 빔에 노출되는 챔버 내에 배치된 프로브에 제 1 신호를 인가하는 단계; 샘플의 특징을 판정하기 위해서 제 1 신호와 제 2 신호를 비교하는 단계; 및 하나의 팁이 그의 열 제거 부분으로서 날카롭게 되는 적어도 하나의 근접-배치된 프로브 팁을 가열하는 단계를 포함할 수 있는 방법을 지원한다.
Abstract:
The invention relates to a positron source which applies, in particular, to solid state physics. The inventive source comprises a thin target (28) which receives a continuous or quasi-continuous beam (22) of electrons of approximately 10 MeV with a grazing incidence and which produces positrons by means of interaction with said beam.
Abstract:
A system and method for providing real-time visual feedback to automatically control actions of multiple autonomous nano-robots with manipulators in order to perform specific nano-manipulation or nano-assembly tasks. Visual feedback may be obtained for the nano-manipulators and the nano-components via an electronic microscopy system. At least one slave Scanning Electron Microscope ("SEM") with imaging system may be implemented with autonomous manipulators inside, and a master controller system with Graphical User Interface ("GUI"). The slave SEM can provide real-time vision feedback for the sensed environment for the master controller, and the master controller provides real-time feedback control command for the required task to the slave SEM
Abstract:
A field emission device comprises one or more emitter elements, each having a high aspect ratio structure with a nanometer scaled cross section; and one or more segmented electrodes, each surrounding one of the one or more emitters. Each of the one or more segmented electrodes has multiple electrode plates. This abstract is provided to comply with rules requiring an abstract that will allow a searcher or other reader to quickly ascertain the subject matter of the technical disclosure. It is submitted with the understanding that it will not be used to interpret or limit the scope or meaning of the claims.
Abstract:
A sample holder for use in a method of analysis using high-energy radiation, includes a frame (4) having a window (6) and a membrane (2) that extends across the window and has a surface (8) for supporting a sample. The membrane is substantially transparent to the high-energy radiation. A functional structure (10, 12, 14, 18, 22, 24, 26, 34, 36) is formed on the membrane, the functional structure providing additional functionality that allows selected parameters of a sample on the support surface to be measured and/or controlled.
Abstract:
The present method relates to processes for the removal of a material from asample by a gas chemical reaction activated bya charged particle beam. The method is a more step process wherein in a first step a gas is supplied which, when a chemical reaction between the gas and the material is activated, forms a non-volatile material component such as a metal salt or a metaloxide. In a second consecutive step the reaction product of the first chemical reaction is removed from the sample.
