Abstract: A method of fabricating an electronic device and the resulting electronic device. The method includes forming a gate oxide on an uppermost side of a silicon-on-insulator substrate; forming a first polysilicon layer over the gate oxide; and forming a first silicon dioxide layer over the first polysilicon layer. A first silicon nitride layer is then formed over the first silicon dioxide layer followed by a second silicon dioxide layer. Shallow trenches are etched through all preceding dielectric layers and into the SOI substrate. The etched trenches are filled with another dielectric layer (e.g., silicon dioxide) and planarized. Each of the preceding dielectric layers are removed, leaving an uppermost sidewall area of the dielectric layer exposed for contact with a later-applied polysilicon gate area. Formation of the sidewall area assures a full-field oxide thickness thereby producing a device with a reduced-electric field and a reduced capacitance between gate and drift regions.

Rotating the workpiece between scans through the fixed ion beam allows for the transient temperature to decay sufficiently for more uniform ion implantation processes to proceed.

Abstract: By aligning the primary flat of a wafer with a (100) plane rather than a (110) plane, devices can be formed with primary currents flowing along the (100) plane. In this case, the device will intersect the (111) plane at approximately 54.7 degrees. This intersect angle significantly reduces stress propagation/relief along the (111) direction and consequently reduces defects as well as leakage and parasitic currents. The leakage current reduction is a direct consequence of the change in the dislocation length required to short the source-drain junction. By using this technique the leakage current is reduced by up to two orders of magnitude for an N-channel CMOS device.

Abstract: A method of fabricating an electronic device and a resulting electronic device. The method includes forming a pad oxide layer on a substrate, forming a silicon nitride layer over the pad oxide layer, and forming a top oxide layer over the silicon nitride layer. A first dopant region is then formed in a first portion of the substrate. A first portion of the top oxide layer is removed; a remaining portion of the top oxide layer is used to align a second dopant mask and a second dopant region is formed. An annealing step drives-in the dopants but oxygen diffusion to the substrate is limited by the silicon nitride layer; the silicon nitride layer thereby assures that the uppermost surface of the silicon is substantially planar in an area proximate to the dopant regions after the annealing step.

Abstract: A first mark, in a double-well integrated circuit technology, is formed by a first etching of a first mask layer on top of an ONO stack. After a first well is doped, a second etching occurs at the first etching sites in the uppermost layer of oxide of the ONO stack forming a first alignment artifact. A second mask layer is applied after removing the first mask layer. A second well doping occurs at second mask layer etching sites to maintain clearance between the two wells within active areas and provide an overlap of the two wells in a frame area. At the first alignment artifact in the overlap of the two wells, further etchings remove remaining layers of the ONO stack and remove silicon from the upper most layer of the semiconductor forming a second registration mark, which may be covered by a protective layer.
