A method of forming a semiconductor line from a semiconductor-on-insulator (SOI) wafer, the SOI wafer having a substrate with a buried oxide (BOX) layer disposed thereon and a semiconductor active layer disposed on the BOX layer. The method includes the steps of (a) forming a dummy island on the active layer; (b) forming a sidewall spacer adjacent the dummy island; (c) removing the dummy island; (d) removing semiconductor material of the active layer left exposed by the sidewall spacer; and (e) removing the sidewall spacer.
Abstract:
A method of fabricating a silicon-on-insulator (SOI) chip having an active layer with a non-uniform thickness. The method includes the steps of providing a substrate; providing a buried oxide layer (BOX) on the substrate; providing an active layer on the BOX layer, the active layer having an initially uniform thickness; dividing the active layer into at least a first and a second tile; and altering the thickness of the active layer in the area of the second tile. The method also includes forming a plurality of partially depleted semiconductor devices from the active layer in the area of a thicker of the first and the second tiles and forming a plurality of fully depleted semiconductor devices from the active layer in the area of a thinner of the first and the second tiles.

Abstract:
A method and a system to provide daisy chain distribution in data centers are provided. A node identification module identifies three or more data nodes of a plurality of data nodes. The identification of three or more data nodes indicates that the respective data nodes are to receive a copy of a data file. A connection creation module to, using one or more processors, create communication connections between the three or more data nodes. The communication connections form a daisy chain beginning at a seeder data node of the three or more data nodes and ending at a terminal data node of the three or more data nodes.
