A method of fabricating a device including imprinting a mold having a protrusion against a substrate having a resist layer such that the protrusion engages the resist layer. The mold further has a mask member positioned generally adjacent the resist layer. Radiation energy is then transmitted through the mold and into the resist layer; however, the mask member substantially prevents transmission of the radiation energy therethrough, thereby defining an unexposed area in the resist layer. Once the mold is removed from the substrate, which consequently forms a first feature from nanoimprinting, the unexposed area of resist layer is removed through dissolving in a developer solution.

A swage hermetic sealing of a MEMS or microdevice or nanodevice package using high force. A cutting and flowing edge 430 is formed on a package cover which is pressed into a mating , integral gasket 425 on a package base. A material extension of the package cover 450 is simultaneously folded under the package base to supply force maintenance for permanent hermaticity. The swage hermetic sealing of single or an array of covers to an extended wafer or substrate is accomplished by a cutting and flowing edge 560. Permanent force maintenance is achieved through a re-entrant cavity 565 and annular ring 535 on the wafer or substrate.

This invention presents a novel method to form uniform or heterogeneous, straight or curved and size-controllable nanostructures including, for example, nanotubes, nanowires, nanoribbons, and nanotapes, including SiNW, using a nanochannel template. In the case of semiconductor nanowires, doping can be included during growth. Electrode contacts are present as needed and may be built in to the template structure. Thus completed devices such as diodes, transistors, solar cells, sensors, and transducers are fabricated, contacted, and arrayed as nanowire or nanotape fabrication is completed. Optionally, the template is not removed and may become part of the structure. Nanodevices such as nanotweezers, nanocantilevers, and nanobridges are formed utilizing the processes of the invention.

A core-shell structure comprises a core (2) comprising nanoparticles and a shell (4) coating the core (2), and its void space (3) formed by the core (2) and the shell (4) is controlled. A method of preparing the core-shell structure comprises: forming particles comprising a photoetchable semiconductor, metal or polymer and coating the particles with a shell (4) comprising a non-photoetchable semiconductor, metal or polymer, to form a core-shell structure (5); and irradiating the core-shell structure with a light having a controlled wavelength in the photoetching solution to form an adjustable void space inside a shell (3) within the core-shell structure by the size-selective photoetching method. The core-shell structure allows the preparation of a catalyst exhibiting an extremely high efficiency, and can be used as a precursor for preparing a nanomaterial required for a nanodevice.
