    Abstract: A main crucible of molten semiconductor is replenished from a supply crucible maintained such that there are always two phases of solid and liquid semiconductor within the supply crucible. Heat added to melt the solid material results in the solid material changing phase to liquid, but will not result in any significant elevation in temperature of the liquid within the supply crucible. The temperature excursions are advantageously small, being less than that which would cause problems with the formed product. The solid product material acts as a sort of temperature buffer, to maintain the supply liquid temperature automatically and passively at or very near to the phase transition temperature. For silicon, excursions are kept to less than 90°C, and even as small as 50°C. The methods also are useful with germanium. Prior art silicon methods that entirely melt the semiconductor experience excursions exceeding 100°C.

    Abstract: Al—Mnx/Al—Mny multilayers with a wide range of structures ranging from microcrystalline to nanocrystalline and amorphous were electrodeposited using a single bath method under galvanostatic control from room temperature ionic liquid. By varying the Mn composition by - 1 - 3 at. % between layers, the grain sizes in one material can be systematically modulated between two values. For example, one specimen alternates between grain sizes of about 21 and 52 nm, in an alloy of average composition of 10.3 at.% Mn. Nanoindentation testing revealed multilayers with finer grains and higher Mn content exhibited better resistance to plastic deformation. Other alloy systems also are expected to be electrodeposited under similar circumstances.

    Abstract: A method for imparting a pattern to a flowable resist material on a substrate entails providing a resist layer so thin that during a stamp wedging process, the resist never completely fills the space between the substrate and the bottom surface of a stamp between wedge protrusions, leaving gap everywhere therebetween. A gap remains between the resist and the extended surface of the stamp. If the resist layer as deposited is somewhat thicker than the targeted amount, it will simply result in a smaller gap between resist and tool. The presence of a continuous gap assures that no pressure builds under the stamp. Thus, the force on the protrusions i determined only by the pressure above the stamp and is well controlled, resulting in well-controlled hole sizes. The gap prevents resist from being pumped entirely out of any one region, and thus prevents any regions from being uncovered of resist. The stamp can be pulsed in its contact with the substrate, repeatedly deforming the indenting protrusions. Several pulses clears away any scum layer better than does a single press, as measured by an etch test comparison of the degree to which a normal etch for a normal duration etches away substrate material.

    Abstract: Power pulsing, such as current pulsing, is used to control the structures of metals and alloys electrodeposited in non-aqueous electrolytes. Using waveforms containing different types of pulses: cathodic, off -time and anodic, internal microstructure, such as grain size, phase composition, phase domain size, phase arrangement or distribution and surface morphologies of the as-deposited alloys can be tailored. Additionally, these alloys exhibit superior macroscopic mechanical properties, such as strength, hardness, ductility and density. Waveform shape methods can produce aluminum alloys that are comparably hard (about 5 GPa and as ductile (about 13% elongation at fracture) as steel yet nearly as light as aluminum; or, stated differently, harder than aluminum alloys, yet lighter than steel, at a similar ductility. Al-Mn alloys have been made with such strength to weight ratios. Additional properties can be controlled, using the shape of the current waveform.

    Abstract: An original wafer, typically silicon, has the form of a desired end PV wafer. The original may be made by rapid solidification or CVD. It has small grains. It is encapsulated in a clean thin film, which contains and protects the silicon when recrystallized to create a larger grain structure. The capsule can be made by heating a wafer in the presence of oxygen, or steam, resulting in silicon dioxide on the outer surface, typically 1-2 microns. Further heating creates a molten zone in space, through which the wafer travels, resulting in recrystallization with a larger grain size. The capsule contains the molten material during recrystallization, and protects against impurities. Recrystallization may be in air. Thermal transfer through backing plates minimizes stresses and defects. After recrystallization, the capsule is removed.

    Abstract: Crystalline silicon PV modules typically use tinned flat copper wire to increase the conductivity of a bus bar metallization and to interconnect to adjacent cells. Such a flat bus wire may be patterned with shallow v-shaped grooves using metal forming techniques, such as rolling, stamping and drawing. The grooves are designed so that incident light is reflected up toward the glass superstrate of t module at an internal interface angle that is large enough (typically greater than about 40°) so that the light undergoes total internal reflection at the glass-air interface and is reflected onto the solar cell. Grooves can be lengthwise along the conductor, or at an angle, angles. Rather than grooves, inclined faces can form pyramids, or other shapes.

    Abstract: A semiconductor wafer forms on a mold containing a dopant. The dopant dopes a melt region adjacent the mold. There, dopant concentration is higher than in the melt bulk. A wafer starts solidifying. Dopant diffuses poorly in solid semiconductor. After a wafer starts solidifying, dopant can not enter the melt. Afterwards, the concentration of dopant in the melt adjacent the wafer surface is less than what was present where the wafer began to form. New wafer regions grow from a melt region whose dopant concentration lessens over time. This establishes a dopant gradient in the wafer, with higher concentration adjacent the mold. The gradient can be tailored. A gradient gives rise to a field that can function as a drift or back surface field. Solar collectors can have open grid conductors and better optical reflectors on the back surface, made possible by the intrinsic back surface field.

    Abstract: A continuum style manipulator is actuated by jammable media within an envelope of a module, which is also actuated by a tensile element, such as a cable and spooler motor. Multiple modules may be reversibly added. Two or more tensile elements may also be used. Three or more actuated tensile elements can actuate three DOFs of each module, and the terminal module, as well as the entire manipulator. Jammable media may be granular, actuated by a pressure change. Coarsely ground coffee works well. Rather than a jammable media, tensile elements may alternatively be used with other phase change media, such as magnetorheological and electrorheological media. A high friction angle of the granular media is desireable, and has been achieved with a particle size dispersion including both small and relatively larger particles. Applications include endoscopes, proctoscopes, laparoscopic instruments, manufacturing and medical manipulators. Methods of actuating include unjamming all modules, positioning the manipulator with tensile elements or otherwise, jamming the base-most module, and then repositioning remaining, not-jammed modules, followed by jamming the base-most not-jammed module, and so on, until all modules are positioned and jammed.

    Abstract: An interposer sheet can be used for making semiconductor bodies, such as of silicon, such as for solar cell use. It is free-standing, very thin, flexible, porous and able to withstand the chemical and thermal environment of molten semiconductor without degradation. It is typically of a ceramic material, such as silica, silicon nitride, silicon oxynitride, silicon oxycarbide, silicon carbide, silicon carbonitride, silicon oxycarbonitride and others. It is provided between a forming surface of a mold sheet, and the molten material from which a semiconductor body will be formed. It may be secured to the forming surface or deposited upon the melt. The interposer sheet suppresses grain nucleation, and limits heat flow from the melt. It promotes separation of the semiconductor body from the forming surface. It can be fabricated before its use. Because free-standing and not adhered to the forming surface, problems of mismatch of CTE are minimized. The interposer sheet and semiconductor body are free to expand and contract relatively independently of the forming surface.

    Abstract: A porous lift off layer facilitates removal of films from surfaces, such as semiconductors. A film is applied over a patterned porous layer, the layer comprising openings typically larger than the film thickness. The porous material and the film are then removed from areas where film is not intended. The porous layer can be provided as a slurry, dried to open porosities, or fugitive particles within a field, which disassociate upon the application of heat or solvent. The film can be removed by etchant that enters through porosities where the film does not bridge the spaces between solid portions, so that the etchant attacks both film surfaces
