    摘要: A new SOI device which permits both the kink effect to be avoided and threshold voltage to be regulated, as well as a new method for fabricating SOI ICs, is disclosed. The new device included an electrically conductive pathway extending from the active volume and terminating in a non-active region of the substrate of the device. A back-gate bias is communicated to, and kink-inducing charges are conducted away from, the active volume through the conductive pathway. The new fabrication methd permits SOI ICs to be fabricated using available circuit designs and pattern delineating apparatus, e.g., IC mask sets. This method involves the formation of a precursor substrate surface which includes islands of insulating material, each of which is encircled by a crystallization seeding area of substantially single crystal semiconductor material. The boundaries of the islands are defined with a first pattern delineating device, e.g., a mask, which, in terms of the pattern it produces, is substantially identical to a second pattern delineating device. The latter device is a component of pattern delineating apparatus used in forming an IC, e.g., an IC mask set, the component being used to delineate the device regions of the IC. A layer of non-single crystal semiconductor material is formed on the precursor substrate surface, and crystallized with little or no displacement of the islands. The pattern delineating apparatus is then used to form an IC in the crystallized material.

    摘要: One or more silicon-integrated-circuit chips are attached, active side up, to the top side of a silicon wafer. The top side of the wafer and all but peripheral portions of the attached chip(s) are then coated with an etch-resistant layer. Subsequently, the chips are etched to form sloped edges between the active areas of the chips and the top side of the wafer. A lithographically defined conductive pattern is then formed on the top side of the wafer and on the sloped edges to connect conductive pads on each chip to conductive pads on other chips and/or to conductive terminals disposed along the periphery of the wafer. In other embodiments, at least one chip of the type described is attached to each side of a wafer. In such embodiments, connections can also be made through vias in the wafer to selectively interconnect pads and/or terminals included on both sides of the wafer. The resulting packaged chip assembly has advantageous performance and cost characteristics.

    摘要: The present invention relates to a light emitting diode with high luminance and method for making the same, and more particularly to a light emitting diode having a transparent window layer which is formed by a semiconductor film of nitrogen-containing compounds. The present invention is mainly directed to growing a window layer of a light emitting diode with a nitrogen-containing compound on the double heterostructure of InGaAlP. Since the energy gap of the nitrogen-containing compound is greater than that of the light emitted from the active layer and is smaller than that of GaP, it is easily to be doped and to form metallic ohmic electrode. Therefore, it is suitable to form a window layer, thereby increasing the light emitting efficiency of a light emitting diode. In addition, the nitrogen-containing compounds can be formed by the current MBE or OMVPE techniques. Therefore, the light emitting diode can be mass-produced and does have industrial applicability.

    摘要: Semiconductor crystal films on a dielectric substrate are advantageously made by a zone melting method. Single-crystal structure is initiated at a seed surface, and made to extend across a dielectric surface by melting and resolidifying.Melting is effected upon irradiation with optical radiation which is focused onto an elongated zone; the zone is moved so as to locally melt successive portions of a layer of precursor material which may be amorphous or polycrystalline. The use of incoherent radiation is convenient, and focusing is typically by using a reflector.The process is conveniently effected under a controlled atmosphere and the layer being crystallized may be encapsulated so that no free semiconductor surface is exposed to an atmosphere.
