    摘要: A method and structure for forming an integrated circuit wafer comprises forming a substrate having first and second portions, depositing a first insulator over the substrate, patterning the first insulator such that the first insulator remains only over the first portion, depositing a second insulator over substrate (the first insulator has different thermal dissipation characteristics than the second insulator), polishing the second insulator to form a planar surface, and attaching a silicon film over the first insulator and the second insulator.

    摘要: A structure and method is provided for fabricating isolated capacitors. The method includes simultaneously forming a plurality of deep trenches and one or more isolation trenches surrounding a group or array of the plurality of deep trenches through a SOI and doped poly layer, to an underlying insulator layer. The method further includes lining the plurality of deep trenches and one or more isolation trenches with an insulator material. The method further includes filling the plurality of deep trenches and one or more isolation trenches with a conductive material on the insulator material. The deep trenches form deep trench capacitors and the one or more isolation trenches form one or more isolation plates that isolate at least one group or array of the deep trench capacitors from another group or array of the deep trench capacitors.

    摘要: Epitaxial deposition of silicon germanium in a semiconductor device is achieved without using masks. Nucleation delays induced by interactions with dopants present before deposition of the silicon germanium are used to determine a period over which an exposed substrate surface may be subjected to epitaxial deposition to form a layer of SiGe on desired parts with substantially no deposition on other parts. Dopant concentration may be changed to achieve desired thicknesses within preferred deposition times. Resulting deposited SiGe is substantially devoid of growth edge effects.
