An isolation layer structure includes first to fourth oxide layer patterns. The first and third oxide layer patterns are sequentially formed in a first trench defined by a first recessed top surface of a substrate and sidewalls of gate structures on the substrate in a first region. The first trench has a first width, and the first and third oxide layer patterns have no void therein. The second and fourth oxide layer patterns are sequentially formed in a second trench defined by a second recessed top surface of the substrate and sidewalls of gate structures on the substrate in a second region. The second trench has a second width larger than the first width, and the fourth oxide layer pattern has a void therein.

A film is formed on a substrate including conductive patterns or trenches using a composition that included a solvent and perhydro-polysilazane having a weight average molecular weight of about 1,800 to 3,000 and a molecular weight distribution of more than about 2.2 to about 3.0. The film is changed into a silicon oxide film, and then an opening is formed through the silicon oxide film. A contact is formed in the opening by filling the opening with conductive material. The silicon oxide film of perhydro-polysilazane having low molecular weight becomes dense and uniform.

A method of forming a hydrocarbon-containing polymer film on a semiconductor substrate by a capacitively-coupled plasma CVD apparatus. The method includes the steps of: vaporizing a hydrocarbon-containing liquid monomer (CαHβXγ, wherein α and β are natural numbers of 5 or more; γ is an integer including zero; X is O, N or F) having a boiling point of about 20° C. to about 350° C. which is not substituted by a vinyl group or an acetylene group; introducing the vaporized gas and CO2 gas or H2 gas into a CVD reaction chamber inside which a substrate is placed; and forming a hydrocarbon-containing polymer film on the substrate by plasma polymerization of the gas, thereby reducing extinction coefficient (k) at 193 nm and increasing mechanical hardness.

摘要:
A wiring structure of a semiconductor device comprises an insulating interlayer, a plug and a conductive pattern. The insulating interlayer has an opening therethrough on a substrate. The plug includes tungsten and fills up the opening. The plug is formed by a deposition process using a reaction of a source gas. A conductive pattern structure makes contact with the plug and includes a first tungsten layer pattern and a second tungsten layer pattern. The first tungsten layer pattern is formed by the deposition process. The second tungsten layer pattern is formed by a physical vapor deposition (PVD) process.

In a method of forming a device isolation layer, a trench is formed in a substrate and a preliminary fin is formed on the substrate using a hard mask pattern on a surface of the substrate as an etching mask. A first thin layer is formed on the bottom and sides of the trench. A lower insulation pattern is formed in a lower portion of the trench on the first thin layer, and an upper insulation pattern is formed on the lower insulation pattern. The upper insulation pattern is etched away so that the first thin layer remains on a side surface of the preliminary fin. A device isolation layer is formed in the lower portion of the trench and a silicon fin is formed having a top surface thereof that is higher relative to a top surface of the device isolation layer.

摘要:
A semiconductor device includes a first structure having a recess having a bottom and opposing side surfaces, and a second structure conformally disposed on the bottom and side surfaces of the recess. The second structure includes a multilayer having two layers having a thickness substantially smaller than a width of the recess. Methods of manufacturing a semiconductor device include providing a first structure having a recess in a deposition chamber and flowing first and second reactants over the first structure for a first period at first and second flow rates. Then, the flow rates of the first second reactants to the first structure are substantially reduced for a pause period. The first and second reactants are then flowed over the first structure for a second period at third and fourth flow rates. The deposition and pause steps may be repeated until a multilayer having a desired thickness is formed.
