The main body cover has a transfer opening for transferring a semiconductor, and the main body cover further has an intake port that generates an air flow in a horizontal direction inside the main body cover.
EXAMINATION CONTAINER AND ELECTRON MICROSCOPE
An examination container includes a main body, a cover and a carrier stage. The main body has an accommodating trough for holding a sample. The cover is detachably connected to the main body to close the accommodating trough. The cover has a first through-hole penetrating through an outer surface and an inner surface of the cover, and includes a membrane arranging on the inner surface of the cover. The membrane has a second through-hole opposite to the first through-hole for passing a charged particle beam through the first through hole and the second through hole. The carrier stage is installed in a position corresponding to the second through-hole. The carrier stage is detachably arranged in the accommodating trough for a variety of examination purposes. An electron microscope using the abovementioned examination container is also disclosed.
Loading station for transferring frozen samples at low temperatures

XRF analyzer with separate source and detector heat sinks
An XRF analyzer can include an x-ray source and an x-ray detector; an x-ray source heat-sink adjacent a side of the x-ray source; and an x-ray detector heat-sink adjacent a side of the x-ray detector. In one embodiment, the x-ray source heat-sink can be separated from the x-ray detector heat sink by a material having a thermal conductivity of less than 20 W/(m*K). In another embodiment, the x-ray source heat-sink can be separated from the x-ray detector heat sink by at least 3 millimeters of a thermally insulating material. In one embodiment, the x-ray source heat-sink can be separated from the x-ray detector heat sink by a segment of the engine component casing. Separation of the heat sinks can help avoid heat from the x-ray source adversely affecting resolution of the x-ray detector.
SUBSTRATE PROCESSING APPARATUS
A substrate processing apparatus includes a processing container configured to air-tightly accommodate substrates, a plurality of mounting stands configured to mount the substrates, a process gas supply part configured to supply a process gas to the mounting stands, an exhaust mechanism configured to evacuate an interior of the processing container, a partition wall configured to independently surround the mounting stands with a gap left between the partition wall and each of the mounting stands, and cylindrical inner walls configured to independently surround the mounting stands with a gap left between each of the inner walls and each of the mounting stands. Slits are formed in the inner walls. The process gas in the processing spaces is exhausted via the slits. The inner walls include partition plates for bypassing the process gas so that the process gas does not directly flow into the slits.
