This invention relates to single session image guided all field simultaneous radiation therapy combined with hyperthermia. Hyperthermia renders the radiation resistant cells as more radiation sensitive cells. The high and super-high dose rate radiation greatly improves the RBE of the photon radiation. It also minimizes photon radiation therapy's OER and cell cycle dependent tumor cell kill by minimizing the repair capacity of cell after photon radiation. Single session hyperthermia and radiation therapy overcomes the thermotolerance-associated inefficiency of hyperthermia treatment as it is when hyperthermia is combined with fractionated, lower dose rate radiation. The synergetic effects of sublethal damage repair inhibiting single session hyperthermia-combined with high dose and dose rate single session radiation therapy, and combined chemotherapy brings the photon radiation therapy's tumor cure and control capabilities closer to high LET radiation therapy.

Treatment of carbon-containing low-k dielectric with UV radiation and a reducing agent enables process-induced damage repair. Also, treatment with a reducing agent and UV radiation is effective to clean a processed wafer surface by removal of metal oxide (e.g., copper oxide) and/or organic residue of CMP slurry from the planarized surface of a processed wafer with or without low-k dielectric. The methods of the invention are particularly applicable in the context of damascene processing to recover lost low-k property of a dielectric damaged during processing, either pre-metalization, post-planarization, or both, and/or provide effective post-planarization surface cleaning to improve adhesion of subsequently applied dielectric barrier and/or other layers.

A medical accelerator system consisting of coplanar and non-coplanar beams, on line magnetic resonance anatomic and functional imaging and cone beam computed tomographic imaging for single session image guided all field simultaneous radiation therapy and radiosurgery is provided. This system enables single session simulation, field-shaping block making, treatment planning, dose calculations and treatment of tumors. The radiation exposure time to the tumor and the normal tissue is reduced to a few seconds to less than a minute. In filed intensity modulated radiation is rendered by combined divergent and pencil beam, multiple smaller fields within a larger field, selectively varying beam's energy, dose rate and beam weight. Since all the treatment fields are treated simultaneously the dose rate at the tumor site is the sum of each of the converging beam's dose rate at depth. This super-high biological dose rate impairs the lethal and sublethal damage repair.

A method for the ultraviolet (UV) treatment of carbon-containing low-k dielectric enables process-induced damage repair. The method is particularly applicable in the context of damascene processing. A method provides for forming a semiconductor device by depositing a carbon-containing low-k dielectric layer on a substrate and forming a trench in the low-k dielectric layer, the trench having sidewalls ending at a bottom. The trench is then exposed to UV radiation and, optionally a gas phase source of —CH₃ groups, to repair damage to the carbon-containing low-k material of the trench sidewalls and bottom caused by the trench formation process (generally etching, ashing, and wet or dry cleaning). A similar treatment, with or without the gas phase source of —CH₃ groups, may be applied to repair damage caused in a subsequent planarization operation.

MTIP (106) further analyzes inbound images using computer vision technology and wire geometry algorithms to determine relative risk and event priority of downed wires. The multi-tenanted intelligent platform (106) is used to store outage-causing damage information and perform damage assessment enabling dispatchers to respond appropriately. A preferred embodiment enables external users—specifically municipal first responders (fire, police and municipal workers) to report outage-causing damage to the electric grid and provides a simple, easily deployable and secure system. The system then uses location, severity and role-based rules to dynamically notify appropriate utility personnel (112) via text message, email notification or within the damage viewing application on the field personnel's mobile device (110) so they are best able to respond and repair the damage. A preferred embodiment also speeds and improves communication between municipalities and utilities, and enhances the transparency of utility damage repair leading to outage resolution.
