Abstract:
Using phase separation technique perforated as well as non-perforated polymeric structures can be made with high aspect ratios (>5). By varying the phase separation process the properties (e.g. porous, non-porous, dense, open skin) of the moulded product can be tuned. Applications are described in the field of micro fluidics (e.g. micro arrays, electrophoretic boards), optics, polymeric solar cells, ball grid arrays, and tissue engineering.
Abstract:
A method may include etching a number of holes into a carrier wafer layer to form a plurality of filters in the carrier wafer layer, pattering a chamber layer over a first side of the carrier wafer layer to form chambers above each filter formed in the carrier wafer layer, forming a layer over the chamber layer, grinding a second side of the carrier wafer layer to expose the number of holes etched into the carrier wafer layer, and bonding a molded substrate to the carrier wafer layer opposite the chamber layer.
Abstract:
A method of forming a membrane with nanometer scale pores includes forming a sacrificial etch stop layer on a substrate. A base layer is constructed on the sacrificial etch stop layer. Micrometer scale pores are formed within the base layer. A sacrificial base layer is built on the base layer. The sacrificial base layer is removed from selected regions of the base layer to define nanometer scale pores within the base layer. The resultant membrane has sub-fifty nanometer pores formed within it.
Abstract:
Surface micromachining and bulk micromachining are employed for realizing a porous membrane (102A) with a bulk substrate (106) to form a particle filter (100). The filter (100) is sufficiently sturdy to allow for easy handling. It may be used as a diffusion barrier and under high pressures. A disclosed etching fabrication method is simple, reliable, and integrated-circuit compatible, and thus amenable to mass production. Electronic circuitry may be integrated on the surface of filter (100), as may be desired for several purposes, such as fluid characterization, capsule formation, or self-cleaning or charging of the surface of filter (100).
Abstract:
An optical component forming a wire grid polarizer comprising: a substrate and microchannels formed by side walls of adjacent microstructures on the substrate, the microchannels being filled with air, the microstructures being covered by a coating and the coating nearly or completely closing the microchannels to substantially separate the microchannels from the environment of the component. A method for producing such an optical component comprises the steps of: providing a substrate, providing microstructures on the substrate, wherein side walls of the microstructures form microchannels; and coating the microstructures thereby nearly or completely closing the microchannels to substantially separate the microchannels from the environment of the component.
Abstract:
The invention relates to a method for the fabrication of a membrane oriented in a (111) plane of a (100) silicon wafer. To this end the method comprises the following steps: applying a mask to both sides of the wafer, wherein portions of the sides are covered by the mask; and the at least partial removal by etching away silicon material from the portions of the two sides of the wafer that are not covered. This method is characterised in that the etching step substantially removes the silicon material forming recesses in the two surfaces of the wafer, such that the walls of the recesses are formed by (111) planes, and in that not covered portions at both sides of the wafer are aligned in relation to one another such that a (111) plane is formed and the distance d between said two planes is less than the thickness of the silicon wafer, so as to form a membrane in the (111) plane having a thickness d. Such a membrane has many application possibilities in the field of MEMS, for example by dividing the membrane into individual cantilevers.
