20140353733 | PROTECTION OF THE GATE STACK ENCAPSULATION - Semiconductor device structures at advanced technologies are provided, wherein a reliable encapsulation of a gate dielectric is already formed during very early stages of fabrication. In illustrative embodiments, a gate stack is formed over a surface of a semiconductor substrate and a sidewall spacer is formed adjacent to the gate stack for covering sidewall surfaces of the gate stack. An additional thin layer is formed over the sidewall spacer, the gate stack and the surface of the semiconductor substrate, and thereafter source/drain extension regions are implanted through the additional thin layer into the substrate in alignment with the sidewall spacer. | 12-04-2014 |
20150021712 | HIGHLY CONFORMAL EXTENSION DOPING IN ADVANCED MULTI-GATE DEVICES - The present disclosure provides in various aspects methods of forming a semiconductor device, methods for forming a semiconductor device structure, a semiconductor device and a semiconductor device structure. In some illustrative embodiments herein, a gate structure is formed over a non-planar surface portion of a semiconductor material provided on a surface of a substrate. A doped spacer-forming material is formed over the gate structure and the semiconductor material and dopants incorporated in the doped spacer-forming material are diffused into the semiconductor material close to a surface of the semiconductor material so as to form source/drain extension regions. The fabricated semiconductor devices may be multi-gate devices and, for example, comprise finFETs and/or wireFETs. | 01-22-2015 |
20150031179 | METHOD OF FORMING A SEMICONDUCTOR STRUCTURE INCLUDING SILICIDED AND NON-SILICIDED CIRCUIT ELEMENTS - A method includes providing a semiconductor structure including at least one first circuit element including a first semiconductor material and at least one second circuit element including a second semiconductor material. A dielectric layer having an intrinsic stress is formed that includes a first portion over the at least one first circuit element and a second portion over the at least one second circuit element. A first annealing process is performed, wherein an intrinsic stress is created at least in the first semiconductor material by stress memorization, and thereafter the first portion of the dielectric layer is removed. A layer of a metal is formed, and a second annealing process is performed, wherein the metal and the first semiconductor material react chemically to form a silicide. The second portion of the dielectric layer substantially prevents a chemical reaction between the second semiconductor material and the metal. | 01-29-2015 |
20150044861 | GATE SILICIDATION - A method for performing silicidation of gate electrodes includes providing a semiconductor device having first and second transistors with first and second gate electrodes formed on a semiconductor substrate, forming an oxide layer on the first and second gate electrodes and the semiconductor substrate, forming a cover layer on the oxide layer, and back etching the cover layer to expose portions of the oxide layer above the first and second gate electrodes while maintaining a portion of the cover layer between the first and second gate electrodes. Furthermore, the exposed portions of the oxide layer are removed from the first and second gate electrodes to expose upper portions of the first and second gate electrodes, while maintaining a portion of the oxide layer between the first and second gate electrodes, and a silicidation of the exposed upper portions of the first and second gate electrodes is performed. | 02-12-2015 |
