The invention concerns a device forming an imprint mould in three dimensions and comprising at least: a substrate, comprising at least one alternation of layers having at least one part perpendicular to the plane of the substrate, in a first type of material and a second type of material which can be etched selectively relative to each other, a surface topology comprising at least: a) first patterns whose top lies at a first level relative to a surface of the substrate located either side of said topology, these first patterns being in a first type of material, b) and second patterns having at least a second level relative to said surface of the substrate, different from and lower than the first level, and these second patterns being in a second type of material.
Abstract:
In one general aspect, methods and articles of manufacture for creating micro-structures are disclosed. In one embodiment, the micro-structures are configured to provide a desired level of hermiticity to other micro-sized devices, such as MEMS and microfluidic devices. In one embodiment, the microstructures are formed from a single species of photoresist, where the photoresist is lithographically patterned to encapsulate the micro-sized device. In general, the ability to form an encapsulating micro-structure from a single photoresist relies in part on applying variable light doses to a later of photoresist to affect a desired level of cross-linking within the photoresist.
Abstract:
An optofluidic lithography system including a membrane, a microfluidic channel, and a pneumatic chamber is provided. The membrane may be positioned between a pneumatic chamber and a microfluidic channel. The microfluidic channel may have a height corresponding to a displacement of the membrane and have a fluid flowing therein, the fluid being cured by light irradiated from the bottom to form a microstructure. The pneumatic chamber may induce the displacement of the membrane depending on an internal atmospheric pressure thereof.
Abstract:
An object of the present invention is to provide a graft pattern-forming method giving a graft pattern allowing formation of a high-resolution pattern that has an oil- and water-repellent region in a commonly-used exposure machine, a lithography method of using the oil- and water-repellent graft pattern formed by the method as an etching stopper, and a conductive pattern-forming method, a color filter forming method, and a microlens production process by using the graft pattern formed by the graft pattern-forming method. The graft pattern-forming method comprises forming a graft polymer-generated region and a non-generated region thereon by bonding a compound having a photopolymerization-initiating site that initiates radical polymerization by photocleavage radical polymerization and a base material-bonding site onto a base material surface in a patterned form, and additionally, by bringing the radically polymerizable compound having an oil- and water-repellent functional group into contact therewith and exposing the entire surface to light, or alternatively, bonding the compound having a polymerization-initiating site that initiates radical polymerization by photocleavage and a base material-bonding site to the base material, bringing a radically polymerizable compound having an oil- and water-repellent functional group into contact therewith, and exposing the region in a patterned form.
Abstract:
A semiconductor device manufacturing method includes forming an insulating layer on a semiconductor substrate, forming, over the insulating layer, a first sacrificial layer having a first opening, and forming, on the sacrificial layer, a first electrode and a dummy body between the first electrode and the first opening. A photoresist is formed on the structure obtained by the previous steps, the photoresist having a second opening that opens inside the first opening. The insulating layer is etched using the photoresist as a mask to expose the semiconductor substrate, and a second electrode is formed in contact with the exposed semiconductor substrate. The sacrificial layer is removed.
Abstract:
Three-dimensional structures of arbitrary shape are fabricated on the surface of a substrate through a series of processing steps wherein a monolithic structure is fabricated in successive layers. A first layer of photoresist material is spun onto a substrate surface and is exposed in a desired pattern corresponding to the shape of a final structure, at a corresponding cross-sectional level in the structure. The layer is not developed after exposure; instead, a second layer of photoresist material is deposited and is also exposed in a desired pattern. Subsequent layers are spun onto the top surface of prior layers and exposed, and upon completion of the succession of layers each defining corresponding levels of the desired structure, the layers are all developed at the same time leaving the three-dimensional structure.
