    Abstract: An array of vertically aligned electron emitting nanotips such as multiwall carbon nanotubes are formed and patterned for use as a lithographic stamp. The spacing and/or arrangement of the nanotips correspond to a predetermined pattern that is desired to be formed on an opposing substrate. Simultaneous actuation of the nanotips by a common electrode forms a pattern on the opposing substrate without any necessary scanning techniques or use of masks. Applying a sufficient electrical potential between the array and the substrate generates electron emission from the tips so as to cure a resist, produce localized electrochemical reactions, establish localized electrostatic charge distributions or perform other desirable coating or etching process steps so as to create nanoelectronic circuitry or to facilitate molecular or nanoscale processing.

    Abstract: Apparatus for electrostatic clamping of a semiconductor wafer includes a dielectric element that defines a clamping surface for receiving the semiconductor wafer and two or more electrodes, including a first electrode disposed at or near a periphery of the clamping surface and a second electrode disposed inwardly of the first electrode. The first and second electrodes have variable widths that form interdigitated projections along adjacent sides of the first and second electrodes. The interdigitated projections limit flexing of the wafer at or near its outer periphery and thereby enhance retention of cooling gas between the semiconductor wafer and the clamping surface.

    Abstract: A scanning electron microscope permitting observation of raw biological specimens containing moisture. A vessel accommodating water supplied to the specimen is formed. A passage is formed in the specimen chamber of the microscope to convey the liquid from the vessel to the specimen. A pipe for introducing a gas such as air is connected with the passage. The introduced gas leaks around the specimen after flowing through the passage to prevent the liquid from freezing in the vessel and in the passage when the specimen chamber is evacuated to a vacuum.
