摘要: Disclosed are semiconductor structure embodiments of a semiconductor-on-insulator region on a bulk substrate. The semiconductor-on-insulator region includes an upper semiconductor layer above and physically separated from the substrate by insulator-containing cavities (e.g., by dielectric layer and/or a pocket of trapped air, of trapped gas, or under vacuum) and, optionally, by a lower semiconductor layer. Disclosed method embodiments include forming openings that extend vertically through the upper semiconductor layer, through a sacrificial semiconductor layer and, optionally, through a lower semiconductor layer to the substrate. Then, a selective isotropic etch process is performed to form cavities, which extend laterally off the sides of the openings into the sacrificial semiconductor layer. Depending upon the embodiments, different process steps are further performed to form plugs in at least the upper portions of the openings and insulators (including dielectric layers and/or a pocket of trapped air, of trapped gas or under vacuum) in the cavities.

摘要: An apparatus has a first gate structure of a core device on a substrate, a first L-shaped spacer covering a sidewall of the first gate and part of the substrate adjacent to the first gate, a first raised source/drain (S/D) structure on the substrate and spaced apart from the first gate by the first L-shaped spacer, a second gate of an I/O device on the substrate, a second L-shaped spacer covering a sidewall of the second gate and part of the substrate adjacent to the second gate, and a second raised S/D structure spaced apart from the second gate by the second L-shaped spacer. The first and second L-shaped spacers have the same spacer width, and a distance between the first gate structure and a sidewall of the first S/D structure is less than a distance between the second gate structure and a sidewall of the second S/D structure.

摘要: A system to abate an emission from a first semiconductor process is disclosed. The system includes an abatement apparatus, such as a gas scrubber, to remove hazardous and toxic gas species from the emission. The abatement apparatus may combust the emission to remove these gas species using a fuel and oxidant. The system includes a fuel assembly fluidly coupled to the abatement apparatus which transmits the fuel from at least one source through the abatement apparatus. The fuel assembly may include a supply tank which contains a volume of fuel, a recovery apparatus which recovers and contains a recovery volume of fuel from a second semiconductor process, and a mass flow controller which may transmit fuel from at least one of the supply tank and the recovery apparatus through the abatement apparatus.
