    • A donor wafer, for example of silicon, has an irregular surface following cleaving of a lamina from the surface, for example by exfoliation following implant of hydrogen and/or helium ions to define a cleave plane. Pinholes in the lamina leave column asperities at the exfoliated surface of the donor wafer, and the beveled edge may leave an edge asperity which fails to exfoliate. To prepare the surface of the donor wafer for reuse, mechanical grinding removes the column and edge asperities, and minimal additional thickness. Following cleaning, growth and removal of an oxide layer at the surface rounds remaining peaks. The smoothed surface is well adapted to bonding to a receiver element and exfoliation of a new lamina. A variety of devices may be fabricated from the lamina, for example a photovoltaic cell.
    • 供体晶片,例如硅,在从表面切割层之后具有不规则表面,例如通过在氢和/或氦离子注入之后通过剥离来限定解理面。 晶片中的针孔在施主晶片的剥离表面处留下柱的粗糙度,并且斜边缘可能留下边缘粗糙,其不能脱落。 为了制备供体晶片的表面以便重新使用,机械研磨去除了柱和边缘粗糙度以及最小的附加厚度。 在清洁之后,在表面处生长和除去氧化物层留下剩余的峰。 平滑的表面很好地适应于接合元件的粘合和新的层的剥离。 可以从薄片制造各种装置,例如光伏电池。

    • 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 a rigid or semi-rigid 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; such adhesives may be unable to tolerate processing temperatures and conditions required to complete the device. 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. A device may be formed which comprises the lamina, such as a photovoltaic cell.
    • 描述了半导体组件,其中在半导体层的表面上构造支撑元件。 形成厚度约为50微米或更小的薄层之后,例如通过镀覆或通过施加前体和原位固化来形成支撑元件,得到支撑元件,其可以用于 例如,金属,陶瓷,聚合物等。这与刚性或半刚性的预成形支撑元件形成对比,该刚性或半刚性的预成型支撑元件在其形成之后固定到层板上,或者与施加器晶片相接触,其中层板随后被切割。 原位制造支撑元件可以避免使用粘合剂将薄片附着到永久支撑元件上; 这种粘合剂可能不能容忍完成装置所需的加工温度和条件。 在一些实施例中,该工艺流程允许薄层在高温下退火,然后在该退火之后具有在层的每个表面上形成的非晶硅层。 可以形成包括层的器件,例如光伏电池。

    • A fastener for coupling a trim panel to a support member includes a mounting grommet with a funnel-shaped receiver communicating with an aperture for receiving one end of a fastener pin having a plurality of spaced annular ratcheting grooves formed thereon. The opposite or second end of the pin includes a pointed end with a pair of resilient locking arms, which extend divergently outwardly and away from an apex of the second end of the pin at an acute angle and at a spacing of about 180°, for insertion into an aperture of a support structure. Interposed between the first and second ends of the fastening pin is a resilient, generally cup-shaped seal which engages a surface of the support structure opposite the locking arms for providing a seal surrounding the aperture in the support structure to which the fastening pin is inserted. The grommet includes an annular slot defined by a collar on one side and a shoulder of the funnel-shaped receiver on the other. The shoulder includes an outwardly extending, resilient, annular flange cooperating with the support structure secured to the trim panel for centering the grommet. A trim panel includes a support socket including a slotted aperture for receiving the shoulder of the grommet and a pair of resilient locking arms which extend to one edge of the aperture for engaging the edge of the collar of the grommet when inserted into the support socket to lock the grommet in place while allowing a slight lateral adjustment for final alignment.
