Abstract:
The invention provides a cross section evaluating apparatus capable of analyzing the cross sectional structure in a state where the temperature of the specimen is regulated. There is disclosed an information acquisition apparatus comprising a stage for placing the specimen, temperature regulation means for regulating the temperature of the specimen, exposure means for exposing a surface, of which information is desired, of the specimen, and information acquisition means for acquiring information relating to the surface exposed by the exposure means.
Abstract:
An electrode structure is provided for use in a plasma device that processes a workpiece (W) using a plasma in a process chamber (26) in a vacuum. An electrode (38) includes a heater (44). The electrode (38) is coupled to a cooling block (40) having a cooling jacket (58) for cooling the electrode. A heat-resistant metal sealant (66A, 66B) covers the electrode in a heat-transfer space (62, 64) formed between the electrode and the cooling block. Gas supply means (94) on the electrode side supplies a heat medium to the space (62, 64). Such an electrode structure maintains the electrode sealed in the space in a high temperature range above 200 DEG C, even at 350 to 500 DEG C, and prevents the gas leakage.
Abstract:
The invention relates to method for examining the surface structures of a sample (14) or for modifying the surface structures of a sample (14) using a beam (11) which strikes the surface structure of said sample (14). According to the inventive method, a gas is intermittently supplied, preferably in a pulsed mode, to the surface structure of the sample (14) at least in the area of incidence (13) of the beam (11).
Abstract:
An apparatus for examining a specimen with a beam of charged particles. The apparatus comprises a particle source for providing a beam of charged particles and an optical device for directing said beam of charged particles onto said specimen to be examined. Furthermore, a gas supply provides inert gas to the area of incidence of said beam of charged particles onto said specimen. The specimen can be loaded into a vacuum chamber.

본 발명은 반응 공간을 제공하는 챔버와, 상기 챔버 내부에 설치되는 스테이지와, 상기 스테이지에 대향하여 상기 챔버 내부에 설치되는 플라즈마 차폐부와, 상기 스테이지와 상기 플라즈마 차폐부 사이에 기판을 거치하는 거치대와, 상기 스테이지에 마련되어 상기 기판의 일면에 반응 가스 또는 비반응 가스를 공급하는 제 1 공급구와, 상기 플라즈마 차폐부에 마련되어 상기 기판의 타면에 반응 가스를 공급하는 제 2 공급구 및 비반응 가스를 공급하는 제 3 공급구를 포함하는 기판 처리 장치 및 기판 처리 방법을 제공한다. 이와 같은 본 발명은 단일 챔버 내에서 기판의 에지 영역 및 배면 영역에 대한 플라즈마 처리를 개별적으로 수행할 수 있다. 따라서, 장비의 설치 공간이 줄어들어 생산 라인의 공간 활용성을 높일 수 있다. 그리고, 챔버 이동에 따른 대기 노출이 없으므로 기판 오염이 적으며, 챔버 이동에 따른 대기 시간이 없으므로 전체적인 공정 시간을 단축할 수 있다. 기판, 플라즈마, 에지 식각, 반응 가스, 비반응 가스, 단일 챔버
Abstract:
A system for imaging a sample through a protective pellicle is disclosed. The system includes an electron beam source configured to generate an electron beam and a sample stage configured to secure a sample and a pellicle, wherein the pellicle is disposed above the sample. The system also includes an electron-optical column including a set of electron-optical elements to direct at least a portion of the electron beam through the pellicle and onto a portion of the sample. In addition, the system includes a detector assembly positioned above the pellicle and configured to detect electrons emanating from the surface of the sample.
