摘要： An improved elastomeric mold for use in fabricating microstructures, the mold having first and second surfaces, the first surface including at least one recessed microchannel and the second surface including an access opening or filling member that extends through the mold to the first surface and communicates with the recessed microchannel. The mold is used by placing it onto a substrate with the recessed microchannel facing the substrate. The access opening of the mold is filled with a liquid material which is capable of solidifying. The access opening continuously introduces the liquid material into the space defined between the microchannel and the substrate. After the liquid material solidifies, the mold is removed from the substrate thereby leaving a microstructure formed from the solidified liquid material on the substrate.

摘要： The invention provides an apparatus for measuring a property of a sample (using, e.g., ISTS) that includes: 1) an excitation laser that generates an excitation laser beam; 2) an optical system aligned along an optical axis that separates the excitation laser beam into at least three sub-beams; 3) an imaging system aligned along the optical axis that collects the sub-beams and focuses them onto the sample to form an optical interference pattern that generates a time-dependent response in the sample; 4) a probe laser that generates a probe laser beam that diffracts off the time-dependent response to form a signal beam; 5) a detector that detects the signal beam and in response generates a radiation-induced electronic response; and 6) a processor that processes the radiation-induced electronic response to determine the property of the sample.

摘要： The invention features a method for detecting a subsurface defect in a thin film structure. The method includes: optically generating an acoustic wave in a first spatial region of the film; optically measuring a time-dependent reflection of the acoustic wave from subsurface features in the film to produce a time-dependent signal; and analyzing the signal to detect an existence of the defect. The optically measuring step can include measuring the diffraction of a probe beam from the reflected acoustic wave. The analyzing step can include comparing the measured signal to a reference signal for defect-free structure.

摘要： Techniques for fabrication of small-scale metallic structures such as microinductors, microtransformers and stents are described. A chemically active agent such as a catalyst is applied from an applicator in a pattern to an exterior surface of an article, metal is deposited according to the pattern and optionally, removed from the substrate. Where the substrate is cylindrical, the pattern can serve as a stent. Alternatively, a pattern of a self-assembled monolayer can be printed on a surface, which pattern can dictate metal plating or etching resulting in a patterned metal structure that can be cylindrical. In another embodiment, a structure is patterned on a surface that serves as a phase-modulating pattern or amplitude-modulating pattern. The article subsequently is exposed to radiation that can induce a change in refractive index within the article, and the phase-modulating or amplitude-modulating pattern results in different indices of refraction being created in different portions of the article. By this technique, a grating can be written into a core of an optical fiber.

摘要： A method for determining the thickness of a thin sample is described. The method includes the step of exciting time-dependent acoustic waveguide modes in the sample with an excitation radiation field. The acoustic waveguide modes are detected by diffracting probe radiation off a ripple morphology induced on the sample's surface by the acoustic waveguide modes. The diffracted probe radiation is then analyzed to measure phase velocities or frequencies of the acoustic waveguide modes. A thickness of the thin sample is determined by comparing the measured phase velocities or frequencies to the phase velocities or frequencies calculated from a mathematical model.

摘要： A transfer printing process that exploits the mismatch in mechanical or thermo-mechanical response at the interface of a printable micro- or nano-device and a transfer stamp to drive the release of the device from the stamp and its non-contact transfer to a receiving substrate are provided. The resulting facile, pick-and-place process is demonstrated with the assembling of 3-D microdevices and the printing of GAN light-emitting diodes onto silicon and glass substrates. High speed photography is used to provide experimental evidence of thermo-mechanically driven release.
