  • Publication number: 20120220068
    Abstract: A semiconductor assembly is described in which a support element is constructed on a surface of a semiconductor lamina. Following formation of the thin lamina, which may have a thickness about 50 microns or less, the support element is formed, for example by plating, or by application of a precursor and curing in situ, resulting in a support element which may be, for example, metal, ceramic, polymer, etc. This is in contrast to pre-formed support element which is affixed to the lamina following its formation, or to a donor wafer from which the lamina is subsequently cleaved. Fabricating the support element in situ may avoid the use of adhesives to attach the lamina to a permanent support element. In some embodiments, this process flow allows the lamina to be annealed at high temperature, then to have an amorphous silicon layer formed on each face of the lamina following that anneal.

  • Patent number: 8212336
    Abstract: FET configurations in which two (or more) facets are exposed on a surface of a semiconductor channel, the facets being angled with respect to the direction of the channel, allow for conformal deposition of a convex or concave S/D. A convex tip of the S/D enhances electric fields at the interface, reducing the resistance between the S/D and the channel. In contrast, a S/D having a concave tip yields a dual-gate FET that emphasizes reduced short-channel effects rather than electric field enhancement. The use of self-limiting, selective wet etches to expose the facets facilitates process control, control of interface chemistry, and manufacturability.

  • Publication number: 20120080676
    Abstract: The absorption coefficient of silicon for infrared light is very low and most solar cells absorb very little of the infrared light energy in sunlight. Very thick cells of crystalline silicon can be used to increase the absorption of infrared light energy but the cost of thick crystalline cells is prohibitive. The present invention relates to the use of less expensive microcrystalline silicon solar cells and the use of backside texturing with diffusive scattering to give a very large increase in the absorption of infrared light. Backside texturing with diffusive scattering and with a smooth front surface of the solar cell results in multiple internal reflections, light trapping, and a large enhancement of the absorption of infrared solar energy.

  • Publication number: 20120070738
    Abstract: A needle-like structure of silicon is provided. A crystalline silicon region is formed over a metal substrate by an LPCVD method, whereby whisker-like crystalline silicon which is a polycrystalline body and grows in the <110> direction or the <211> direction with {111} the plane as a twin boundary can be obtained. Whisker-like crystalline silicon grows while forming a twin crystal (introducing stacking faults), and an initial nucleus is provided so that the normal direction <111> of the twin boundary is always included in the plane perpendicular to the growth direction of whisker-like crystalline silicon (in a transverse cross section). Such a material is used as a negative electrode active material of a lithium-ion secondary battery and for a photoelectric conversion device such as a solar battery.

  • Patent number: 8093684
    Abstract: The semiconductor of the present invention has iron sulfide and a forbidden band control element contained in the iron sulfide. The forbidden band control element has a property capable of controlling the forbidden band of iron sulfide on the basis of the number density of the forbidden band control element in the iron sulfide. An n-type semiconductor is manufactured by incorporating a group 13 element of the IUPAC system into iron sulfide. Moreover, a p-type semiconductor is manufactured by incorporating a group Ia element into iron sulfide. A semiconductor junction device or a photoelectric converter is manufactured by using the n-type semiconductor and the p-type semiconductor.

  • Patent number: 8093590
    Abstract: In order to form a metal thin film, a silicide film, or the like between an upper-layer unit cell and a lower-layer unit cell in stacked-layer photoelectric conversion devices, a step of forming the thin film is additionally needed. Therefore, a problem such as decline in productivity of the photoelectric conversion devices occurs. A first unit cell including a single crystal semiconductor layer with a thickness of 10 ?m or less as a photoelectric conversion layer and a second unit cell including a non-single-crystal semiconductor layer as a photoelectric conversion layer, which is provided over the first unit cell, are at least included, and conductive clusters are dispersed between the unit cells. The conductive clusters are located between the lower-layer unit cell and the upper-layer unit cell to form an ohmic contact; thus, current flows between the both unit cells.
