  • Patent number: 8580037
    Abstract: A method of depositing materials on a non-planar surface is disclosed. The method is effectuated by rotating non-planar substrates as they travel down a translational path of a processing chamber. As the non-planar substrates simultaneously rotate and translate down a processing chamber, the rotation exposes the whole or any desired portion of the surface area of the non-planar substrates to the deposition process, allowing for uniform deposition as desired. Alternatively, any predetermined pattern is able to be exposed on the surface of the non-planar substrates. Such a method effectuates manufacture of non-planar semiconductor devices, including, but not limited to, non-planar light emitting diodes, non-planar photovoltaic cells, and the like.

  • Patent number: 8109004
    Abstract: A scribing system comprising a mounting mechanism, stylus, and force generating mechanism is provided. The mounting mechanism is configured to rotate an elongated object in such a manner that the object is subjected to a bow effect wherein a middle portion of the object bends relative to the end portions of the object. The stylus is for scribing the object at a position x along the long dimension of the object while the mounting mechanism rotates the object. The force generating mechanism is connected to the stylus so that the stylus applies the same constant force to the elongated object regardless of the position x along the long dimension of the object that the stylus is positioned, while the mounting mechanism rotates the object and thereby subjects the object to the bow effect, thereby scribing the object.
