    摘要: Lithography tools and substrates are aligned by generating geometric interference patterns using optical gratings associated with the lithography tools and substrates. In some embodiments, the relative position between a substrate and lithography tool is adjusted to cause at least one geometric shape to have a predetermined size or shape representing acceptable alignment. In additional embodiments, Moiré patterns that exhibit varying sensitivity are used to align substrates and lithography tools. Furthermore, lithography tools and substrates are aligned by causing radiation to interact with optical gratings positioned between the lithography tools and substrates. Lithography tools include an optical grating configured to generate a portion of an interference pattern that exhibits a sensitivity that increases as the relative position between the tools and a substrate moves towards a predetermined alignment position.

    摘要: The invention is directed to methods for direct patterning of silicon. The invention provides the ability to fabricate complex surfaces in silicon with three dimensional features of high resolution and complex detail. The invention is suitable, for example, for use in soft lithography as embodiments of the invention can quickly create a master for use in soft lithography. In an embodiment of the invention, electrochemical etching of silicon, such as a silicon wafer, for example, is conducted while at least a portion of the silicon surface is exposed to an optical pattern. The etching creates porous silicon in the substrate, and removal of the porous silicon layer leaves a three-dimensional structure correlating to the optical pattern.

    摘要: A contact lithography alignment system and method use nanoscale displacement sensing and estimation (nDSE) to maintain an alignment and compensate for a disturbance of one or more objects during contact lithography. A method of maintaining an alignment includes establishing an initial alignment of one or more objects and employing nDSE-based feedback control of relative positions of more or more of the objects to maintain the alignment during contact lithography. A method of disturbance compensation includes acquiring a first image, acquiring a second image, estimating an alignment error using nDSE applied to the first and second image, and adjusting a relative position to reduce the alignment error. A contact lithography system includes an optical sensor, a feedback processor providing nDSE and a position controller that adjusts relative positions of one or more objects to reduce an alignment error determined using the nDSE.

    摘要: A measurement process or system transforms image data corresponding to images of an object to the frequency domain and analyzes the frequency domain data to determine a displacement of the object occurring between first and second images. Analysis in the frequency domain simplifies identification and handling of data expected to be noisy. In particular, frequencies corresponding to modes of vibration, lighting variation, or sensor error characteristic of a measurement system or frequencies corresponding to small magnitude frequency-domain data can be given little or no weighting in analysis that provides the displacement measurement. In one embodiment, Fourier transforms of shifted and unshifted images differ by a phase delay. A least square fit slope of the phase values associated with the phase delay can indicate displacements to accuracies less than 1% of a pixel width, thereby providing nanometer scale precision using imaging systems having a pixel width of about 1 μm.

    摘要: The invention is a combined air freshener and portable device mount which diffuses aromatic fragrance compounds contained in the main cavity of the invention and at the same time engages a fastener mounted on a personal device. The fastener can be but is not limited to ferromagnetic, detent based, or hook and loop fasteners. An elastic member wraps around the main cavity wall at the proximal end and provides friction and cushion for the personal device when it is held by the fastener. Helical threading on the main body engages compatible helical threading on a support structure, allowing the invention to be mounted in a variety of locations in a vehicle interior.
