    Abstract: A particle manipulation system uses a MEMS-based, microfabricated particle manipulation device which has an inlet channel, output channels, and a movable member formed on a substrate. The movable member moves parallel to the fabrication plane, as does fluid flowing in the inlet channel. The movable member separates a target particle from the rest of the particles, diverting it into an output channel. However, at least one output channel is not parallel to the fabrication plane. The device may be used to separate a target particle from non-target material in a sample stream. The target particle may be, for example, a stem cell, zygote, a cancer cell, a T-cell, a component of blood, bacteria or DNA sample, for example. The particle manipulation system may also include a microfluidic structure which focuses the target particles in a particular portion of the inlet channel.

    Abstract: A process is disclosed for using two polymeric bonding material layers to bond a device wafer and carrier wafer in a way that allows debonding to occur between the two layers under low-force conditions at room temperature. Optionally, a third layer is included at the interface between the two layers of polymeric bonding material to facilitate the debonding at this interface. This process can potentially improve bond line stability during backside processing of temporarily bonded wafers, simplify the preparation of bonded wafers by eliminating the need for specialized release layers, and reduce wafer cleaning time and chemical consumption after debonding.

  • Patent number: 8585910
    Abstract: A process for producing a micromachined tube (microtube) suitable for microfluidic devices. The process entails isotropically etching a surface of a first substrate to define therein a channel having an arcuate cross-sectional profile, and forming a substrate structure by bonding the first substrate to a second substrate so that the second substrate overlies and encloses the channel to define a passage having a cross-sectional profile of which at least half is arcuate. The substrate structure can optionally then be thinned to define a microtube and walls thereof that surround the passage.

  • Publication number: 20130270225
    Abstract: A method is provided for producing a microstructured molded object that is intended for culturing of biological cells. According to this method, a plastically deformable first porous film is prepared, as well as a deformable second film and a deformable sacrificial film. The first, second and sacrificial film are placed in a stack. Next, the sacrificial film is subjected to pressure to press the stack into a mold. The mold has recesses, such that deformed regions in the form of cavities are produced in the sacrificial film, the first film and the second film, and undeformed regions remain. During the pressing of the film stack into the mold, the first film and the second film are joined to each other, so that they form a composite film. At least portions of the deformed regions of the second film are etched so that sections of the second film are chemically dissolved.

  • Patent number: 8522427
    Abstract: A multi-layer structure including a base insulating layer and a thin metal film layer (seed layer) is prepared. A plating resist layer is formed to have a prescribed pattern on the upper surface of the thin metal film layer. A metal plating layer is formed on the thin metal film layer exposed by electroplating. Then, the plating resist layer is removed, and the thin metal film layer in the region having the plating resist layer is removed. In this way, a conductive pattern including the thin metal film layer and the metal plating layer is formed. The upper surface of the base insulating layer in the region without the conductive pattern is subjected to roughening treatment. A cover insulating layer is formed on the upper surfaces of the base insulating layer and the conductive pattern. In this way, a printed circuit board is completed.

  • Patent number: 8524097
    Abstract: Plasma etching of a liquid dielectric material such as a polyurethane solution results in volatile byproducts that are deposited onto the surface of an inert substrate. The surface treatment increases adhesiveness so that the surface of the inert material may be bonded to another material. Portions of a medical device comprising an inert substrate such as a fluoropolymer may therefore be securely affixed to other portions of the medical device formed of polymeric, metallic, or ceramic materials.
