In a process for producing an oriented inorganic crystalline film, a non-monocrystalline film containing inorganic crystalline particles is formed on a substrate by a liquid phase technique using a raw-material solution which contains a raw material and an organic solvent, where the inorganic crystalline particles have a layered crystal structure and are contained in the raw material. Then, the non-monocrystalline film is crystallized by heating the non-monocrystalline film to a temperature equal to or higher than the crystallization temperature of the non-monocrystalline film so that part of the inorganic crystalline particles act as crystal nuclei.

Method and structure for optimizing dual damascene patterning with polymeric dielectric materials are disclosed. Certain embodiments of the invention comprise polymeric sacrificial light absorbing materials (“polymer SLAM”) functionalized to have a controllable solubility switch wherein such polymeric materials have substantially the same etch rate as conventionally utilized polymeric dielectric materials, and subsequent to chemical modification of solubility-modifying protecting groups comprising the SLAM materials by thermal treatment or in-situ generation of an acid, such SLAM materials become soluble in weak bases, such as those conventionally utilized to remove materials in lithography treatments.

A corrosion resistant component of semiconductor processing equipment such as a plasma chamber includes a diamond containing surface and process for manufacture thereof.

The present invention describes a method and apparatus for forming a uniform silicon containing film in a single wafer reactor. According to the present invention, a silicon containing film is deposited in a resistively heated single wafer chamber utilizing a process gas having a silicon source gas and which provides an activation energy less than 0.5 eV at a temperature between 750° C.-550° C.

Methods are provided for producing SiGe-on-insulator structures and for forming strain-relaxed SiGe layers on silicon while minimizing defects. Amorphous SiGe layers are deposited by CVD from trisilane and GeH₄. The amorphous SiGe layers are recrystallized over silicon by melt or solid phase epitaxy (SPE) processes. The melt processes preferably also cause diffusion of germanium to dilute the overall germanium content and essentially consume the silicon overlying the insulator. The SPE process can be conducted with or without diffusion of germanium into the underlying silicon, and so is applicable to SOI as well as conventional semiconductor substrates.

Disclosed is a natural-superlattice homologous single-crystal thin film, which comprises a complex oxide which is epitaxially grown on either one of a ZnO epitaxial thin film formed on a single-crystal substrate, the single-crystal substrate after disappearance of the ZnO epitaxial thin film and a ZnO single crystal. The complex oxide is expressed by the a formula: M¹M²O₃ (ZnO)_m, wherein M¹ is at least one selected from the group consisting of Ga, Fe, Sc, In, Lu, Yb, Tm, Er, Ho and Y, M² is at least one selected from the group consisting of Mn, Fe, Ga, In and Al, and m is a natural number of 1 or more. A natural-superlattice homologous single-crystal thin film formed by depositing the complex oxide and subjecting the obtained layered film to a thermal anneal treatment can be used in optimal devices, electronic devices and X-ray optical devices.

The present invention provides microfabricated substrates and methods of conducting reactions within these substrates. The reactions occur in plugs transported in the flow of a carrier-fluid.

A pulse laser beam having a rectangular irradiation region is irradiated on the same point in a non-single crystal semiconductor film multiple times. The pulse laser beam has an energy profile in a longitudinal direction in the beam irradiation region as follows: (a) there are the first region having an energy density of Ea or higher and the second regions on both sides of the first region having an energy density of less than Ea, and (b) an energy density slope has an absolute value of 20 to 300 J/cm3 in a boundary region extending to 1 mum from the boundary line between the first and the second regions.

A p-type field effect transistor (PFET) and an n-type field effect transistor (NFET) of an integrated circuit are provided. A first strain is applied to the channel region of the PFET but not the NFET via a lattice-mismatched semiconductor layer such as silicon germanium disposed in source and drain regions of only the PFET and not of the NFET. A process of making the PFET and NFET is provided. Trenches are etched in the areas to become the source and drain regions of the PFET and a lattice-mismatched silicon germanium layer is grown epitaxially therein to apply a strain to the channel region of the PFET adjacent thereto. A layer of silicon can be grown over the silicon germanium layer and a salicide formed from the layer of silicon to provide low-resistance source and drain regions.

A pressure vessel for processing at least one material in a supercritical fluid. The pressure vessel includes a self-pressurizing capsule for containing at least one material and the supercritical fluid in a substantially air-free environment, a pressure transmission medium surrounding the capsule for maintaining an outer pressure on the capsule, at least one heating element insertable in the pressure transmission medium such that the heating element surrounds the capsule, a temperature measurement means for measuring a temperature of the capsule, a temperature controller for controlling the temperature and providing power to the heating element, a restraint to contain and hold in place the capsule, the pressure transmission medium, and the heating element, and at least one seal between the restraint and the pressure transmission medium for preventing escape of the pressure transmission medium. Methods of using the pressure vessel, processing a material at high temperature and high pressure in the presence of a supercritical fluid within the capsule are also described.

An evaporation apparatus with high utilization efficiency for EL materials and excellent film uniformity is provided. The invention is an evaporation apparatus having a movable evaporation source and a substrate rotating unit, in which the space between an evaporation source holder and a workpiece (substrate) is narrowed to 30 cm or below, preferably 20 cm, more preferably 5 to 15 cm, to improve the utilization efficiency for EL materials. In evaporation, the evaporation source holder is moved in the X-direction or the Y-direction, and the workpiece (substrate) is rotated for deposition. Therefore, film uniformity is improved.
