  • Publication number: 20140334768
    Abstract: Planar lightwave circuits with a polymer coupling waveguide optically coupling a planar waveguide over a first region of a substrate to an optical component, such as a laser, affixed to a second region of the substrate. The coupling waveguide may be formed from a polymer layer applied over the planar waveguide and optical component such that any misalignment between the two may be accommodated by patterning the polymer into a waveguide having a first end aligned to an end of the planar waveguide and a second end aligned to an edge of the optical component. In embodiments, the polymer is photo-definable, such as a negative resist, and may be patterned through direct laser writing. In embodiments, the optical component is a thin film affixed to the substrate through micro-transfer printing. In other embodiments, the optical component is a semiconductor chip affixed to the substrate by flip-chip bonding.

  • Patent number: 8399922
    Abstract: A method for fabricating double-gate and tri-gate transistors in the same process flow is described. In one embodiment, a sacrificial layer is formed over stacks that include semiconductor bodies and insulative members. The sacrificial layer is planarized prior to forming gate-defining members. After forming the gate-defining members, remaining insulative member portions are removed from above the semiconductor body of the tri-gate device but not the I-gate device. This facilitates the formation of metallization on three sides of the tri-gate device, and the formation of independent gates for the I-gate device.

  • Patent number: 7968392
    Abstract: Dual-gate memory cells and tri-gate CMOS devices are integrated on a common substrate. A plurality of silicon bodies are formed from a monocrystalline silicon on the substrate to define a plurality of transistors including dual-gate memory cells, PMOS transistors, and NMOS transistors. An insulative layer is formed overlying the silicon body of the memory cell. A layer of a high-k dielectric and at least a metal layer cover the silicon bodies and their overlying layers. Next, gain regions of the transistors are filled with polysilicon. Thus, a gate is formed on the top surface and both sidewalls of a tri-gate transistor. Thereafter, the high-k dielectric and the metal layer overlying the insulative layer of the memory cell are removed to expose the insulative layer. Thus, two electrically-isolated gates of the memory cell are formed.
