摘要:
A transparent substrate as formed on its front side a layer of amorphous silicon. A laser beam is used to irradiate through the backside of the transparent substrate in order to form buried nucleation sites within the amorphous silicon. The buried nucleation sites which are used as nucleation seeds are then used during a front side crystallization process in order to form large single silicon crystals over the substrate surface.

The invention provides a buffered substrate that includes a substrate, a buffer layer and a silicon layer. The buffer layer is disposed between the substrate and the silicon layer. The buffer layer has a melting point higher than a melting point of the substrate. A polycrystalline silicon layer is formed by crystallizing the silicon layer using a laser beam.

An HTSC material epitaxially deposited on a YSZ buffer layer on a surface of a monocrystalline silicon substrate has a zero resistance transition temperature of at least 85.degree. K., a transition width (10-90%) of no more than 1.0.degree. K., a resistivity at 300.degree. K. of no more than 300 micro-ohms-centimeter and a resistivity ratio (at 300.degree. K./100.degree. K.) of 3.0.+-. 0.2. The surface of the silicon substrate is cleaned using a spin-etch process to produce an atomically clean surface terminated with an atomic layer of an element such as hydrogen with does not react with silicon. The substrate can be moved to a deposition chamber without contamination. The hydrogen is evaporated in the chamber, and then YSZ is epitaxially deposited preferably by laser ablation. Thereafter, the HTSC material, such as YBCO, is epitaxially deposited preferably by laser ablation. The structure is then cooled in an atmosphere of oxygen.

A hybrid structure or device is provided wherein carried on a single substrate is at least one micro-spring interconnect having an elastic material that is initially fixed to a surface of the substrate, an anchor portion which is fixed to the substrate surface and a free portion. The spring contact is self-assembling in that as the free portion is released it moves out of the plane of the substrate. Also integrated on the substrate is a sensor having an active layer and contacts. The substrate and sensor may be formed of materials which are somewhat partially transparent to light at certain infrared wavelengths. The integrated sensor/spring contact configuration may be used in an imaging system to sense output from a light source which is used for image formation. The light source may be a laser array, LED array or other appropriate light source. The sensor is appropriately sized to sense all or some part of light from the light source. The sensor may also be sufficiently transparent so that light is not blocked from its emission path, with a contrast ratio such that it only absorbs a small fraction of light passing therethrough. An additional characteristic is that the manufacturing process is compatible with the manufacturing process for the micro-spring interconnects. Data from the sensor is used as light source correction information. This information is provided to a calibration configuration which allows for calibration of high-speed systems.

Several methods and structures for improving the yield of out-of-plane micro-device structures including springs and coils are described. In one method the springs used to form out-of-plane structures are constrained via a tether to avoid bunching and entanglement. The high yield structure may be used in numerous electronic applications such as filter circuits.

An extrusion device has a stack of at least two layers, the stack including an outlet, an inlet for a first material, and a feed channel for the first material arranged to fluidically connect to the inlet for the first material, the feed channel having a sloped end. A method of manufacturing an extrusion device includes forming an outlet, an inlet for a first material and a feed channel for the first material having a sloped end in a stack of layers, aligning the stack of layers to fluidically connect the feed channel for the first material with the inlet for the first material and to fluidically connect the inlet for the first material with the outlet, and bonding the layers together.
摘要:
Various structures, such as microstructures and wall-like structures, can include parts or surfaces that are oblique. In some implementations, a cantilevered element includes a spring-like portion with a uniformly oblique surface or with another artifact of an oblique radiation technique. In some implementations, when a deflecting force is applied, a spring-like portion can provide deflection and spring force within required ranges. Various oblique radiation techniques can be used, such as radiation of a layer through a prism, and structures having spring-like portions with oblique radiation artifacts can be used in various applications, such as with downward or upward deflecting forces.
