Low temperature formation of high quality silicon oxide films in semiconductor device manufacturing

Silicon oxide layer is deposited on a semiconductor substrate by PECVD at a temperature of less than about 200° C. and is treated with helium plasma to reduce stress of the deposited layer to an absolute value of less than about 80 MPa. Plasma treatment reduces hydrogen content in the silicon oxide layer, and leads to low stress films that can also have high density and low roughness. In some embodiments, the film is deposited on a semiconductor substrate that contains one or more temperature-sensitive layers, such as layers of organic material or spin-on dielectric that cannot withstand temperatures of greater than 250° C. In some embodiments the silicon oxide film is deposited to a thickness of between about 100-200 Å, and is used as a hardmask layer during etching of other layers on a semiconductor substrate.

The reactor is either operated in a catalytic hydrogenation mode to convert olefins into saturated hydrocarbons and / or to chemically reduce sulfur species to hydrogen sulfide or a catalytic oxidative mode utilizing oxygen and steam to prereform the feed and thus, increase the hydrogen content of a synthesis gas produced by a steam methane reformer. The method is applicable to the treatment of feed streams containing at least 15% by volume of hydrocarbons with two or more carbon atoms and / or 3% by volume of olefins, such as a refinery off-gas.

Formation evaluation combination system for petrophysical well log analysis

A method of measuring characteristics of a geologic formation, using the time, energy and spatial spectra of gamma rays induced by an accelerator, which allows (i) the measurement of the photoelectric absorption (Pe) factor of the formation using a gamma-ray spectrum detected from gamma rays induced in the formation, (ii) the calculation of a neutron porosity of the formation using the gamma-ray spectrum, and (iii) the determination of a bulk density of the formation using the spectroscopic measurements. The Pe factor may be inferred by directly mapping the spectroscopic measurements. The porosity may be calculated by relating the gamma-ray spectrum to a hydrogen content of the formation. The density may be determined by computing a gamma diffusion length of the formation based on the gamma-ray spectrum. In addition to these measurements, the resistivity of the formation and its spontaneous potential may also be measured using an electromagnetic induction system.
