  • Patent number: 8129251
    Abstract: A METAL-INSULATOR-METAL structured capacitor is formed with polysilicon instead of an oxide film as a sacrificial layer material that defines a storage electrode region. A MPS (Meta-stable Poly Silicon) process is performed to increase the surface area of the sacrificial layer that defines the storage electrode region and also increase the area of the storage electrode formed over sacrificial layer. This process results in increasing the capacity of the capacitor in a stable manner.

  • Patent number: 7816153
    Abstract: A dislocation-free sheet may be formed from a melt. A sheet of material with a first width is formed on a melt of the material using a cooling plate. This sheet has dislocations. The sheet is transported with respect to the cooling plate and the dislocations migrate to an edge of the sheet. The first width of the sheet is increased to a second width by the cooling plate. The sheet does not have dislocations at the second width. The cooling plate may have a shape with two different widths in one instance. The cooling plate may have segments that operate at different temperatures to increase the width of the sheet in another instance. The sheet may be pulled or flowed with respect to the cooling plate.
