Abstract:
A pressure sensor having a diaphragm having a boss with a pattern. The diaphragm having a boss may be regarded as a bossed diaphragm. The bossed diaphragm may have higher sensitivity than a flat plate diaphragm having the same area as the bossed diaphragm. The bossed diaphragm may incorporate a simple cross pattern that can further improve the sensitivity and linearity of a pressure response of the diaphragm at low pressures. Reduction of sharp edges and corners of the boss and its legs around the periphery of the diaphragm may reduce high stress points and thus increase the burst pressure rating of the bossed diaphragm.

Abstract:
Block copolymers can be self-assembled and used in methods as described herein for sub-lithographic patterning, for example. The block copolymers can be diblock copolymers, triblock copolymers, multiblock copolymers, or combinations thereof. Such methods can be useful for making devices that include, for example, sub-lithographic conductive lines.

Abstract:
A shadow mask, a method of manufacturing the shadow mask, and a method of forming a thin film using the shadow mask are provided. The shadow mask includes an upper layer and a lower layer. The upper layer includes a first opening. The lower layer is formed on a lower surface of the upper layer around the first opening and includes an opening having the same size as the first opening. When the thin film is formed using the shadow mask, the lower layer of the shadow mask is close to the edge of a cavity of a substrate, and a position on which the thin film may be formed as defined by the lower layer of the shadow mask. Therefore, the thickness of the thin film can be uniform.

Methods for fabricating a random graft PS-r-PEO copolymer and its use as a neutral wetting layer in the fabrication of sublithographic, nanoscale arrays of elements including openings and linear microchannels utilizing self-assembling block copolymers, and films and devices formed from these methods are provided. In some embodiments, the films can be used as a template or mask to etch openings in an underlying material layer.
Abstract:
In a method for transferring nanostructures into a substrate, the following order of steps is used: decorating a substrate with nanomaterials (13), etching the substrate (10), applying a coating (15), removing the nanomaterials (13), and etching the substrate (10).
Abstract:
In one embodiment, Hexagonal tiles encompassing a large are divided into three groups, each containing ⅓ of all hexagonal tiles that are disjoined among one another. Openings for the hexagonal tiles in each group are formed in a template layer, and a set of self-assembling block copolymers is applied and patterned within each opening. This process is repeated three times to encompass all three groups, resulting in a self-aligned pattern extending over a wide area. In another embodiment, the large area is divided into rectangular tiles of two non-overlapping and complementary groups. Each rectangular area has a width less than the range of order of self-assembling block copolymers. Self-assembled self-aligned line and space structures are formed in each group in a sequential manner so that a line and space pattern is formed over a large area extending beyond the range of order.
Abstract:
According to one embodiment, a first pattern is formed at first pattern coverage in a first region on a film to be processed and a second pattern is formed at second pattern coverage in a second region on the film to be processed. During the formation of the second pattern, a second film formed of a block copolymer containing film or the like is formed on the film to be processed and is self-assembled. A plurality of kinds of polymers contained in the self-assembled second film are selectively removed to leave at least one kind of polymer to form the second pattern to bring the second coverage close to the first pattern coverage.
