The present invention relates to a method of forming an amorphous carbon film and a method of manufacturing a semiconductor device using the method. An amorphous carbon film is formed on a substrate by vaporizing a liquid hydrocarbon compound, which has chain structure and one double bond, and supplying the compound to a chamber, and ionizing the compound. The amorphous carbon film is used as a hard mask film.It is possible to easily control characteristics of the amorphous carbon film, such as a deposition rate, an etching selectivity, a refractive index (n), a light absorption coefficient (k) and stress, so as to satisfy user's requirements. In particular, it is possible to lower the refractive index (n) and the light absorption coefficient (k). As a result, it is possible to perform a photolithography process without an antireflection film that prevents the diffuse reflection of a lower material layer.Further, a small amount of reaction by-product is generated during a deposition process, and it is possible to easily remove reaction by-products that are attached on the inner wall of a chamber. For this reason, it is possible to increase a cycle of a process for cleaning a chamber, and to increase parts changing cycles of a chamber. As a result, it is possible to save time and cost.

Method of hydraulic fracturing to reduce unwanted water production

A method of hydraulically fracturing a hydrocarbon-bearing subterranean formation ensures that the conductivity of water inflow below the productive zone of the subterranean formation is reduced. The method consists of two principal steps. In the first step, a fracture in and below the productive zone of the formation is initiated by introducing into the subterranean formation a fluid, free of a proppant, such as salt water, fresh water, brine, liquid hydrocarbon, and / or nitrogen or other gases. The proppant-free fluid may further be weighted. In the second step, a proppant laden slurry is introduced into the subterranean formation which contains a relatively lightweight density proppant. Either the fluid density of the proppant-free fluid is greater than the fluid density of the proppant laden slurry or the viscosity of the proppant-free fluid is greater than the viscosity of the proppant laden slurry. The method limits undesirable fracture height growth in the hydrocarbon-bearing subterranean formation during the fracturing.

System and method for extraction of hydrocarbons by in-situ radio frequency heating of carbon bearing geological formations

A method of producing liquid hydrocarbons from a hydrocarbon-bearing rock in situ in a geological formation begins with exploring the formation by drilling a plurality of boreholes into the formation and taking core samples of the hydrocarbon-bearing rock and at least one overburden layer. Electrical parameters of the hydrocarbon-bearing rock and the overburden layer are determined, as well as a roughness of a boundary between the hydrocarbon-bearing rock and the at least one overburden layer. These electrical parameters are used to construct a computer model of a portion of the hydrocarbon-bearing rock and at least one overburden layer, the computer model based upon modeling the formation as a rough-walled waveguide. This computer model is used to simulate propagation of radio frequency energy within the hydrocarbon-bearing rock, including simulation of radio frequency wave confinement within the hydrocarbon-bearing rock, at several frequencies and temperatures. A frequency for retorting is selected based upon simulation results. Radio frequency couplers are installed into at least one borehole in the hydrocarbon-bearing rock and driven with radio frequency energy to heat the hydrocarbon-bearing rock. As the rock heats, it releases carbon compounds and these are collected.

Integrated Biofuel Production System

According to an embodiment, a biomass conversion subsystem produces methane and / or alcohol and residual biomass. A pyrolysis or a gasification subsystem is used to produce thermal energy and / or process gasses. The thermal energy may be stored thermal energy in the form of a pyrolysis oil. A fuel conversion subsystem produces liquid hydrocarbon fuels from the methane and / or alcohol using thermal energy and / or process gasses produced by the gasification or pyrolysis subsystem. Because the biomass production system integrates the residual products from biomass conversion and the residual thermal energy from pyrolysis or gasification, the overall efficiency of the integrated biomass production system is greatly enhanced.
