Abstract:
A radical source is movably provided in a processing vessel holding a substrate, and the location or driving energy of the radical source is set such that the film formed on the substrate has a uniform thickness. Further, a radical source is provided at a first side of the substrate and a radical flow is formed such that the radical flow flows from the first side of the substrate surface to the other side. By optimizing the condition of the radical flow, the film formed on the substrate has a uniform thickness.
Abstract:
There is provided a deposition system (1) for yielding substantially uniform deposition of an evaporant material onto a substrate. The deposition system (1) comprises: a source (10) for generating a coherent energy beam; a substantially planar target (60) containing the evaporant material and disposed in spaced relation to the substrate; a focusing element (30) optically coupled to the source for focusing the coherent energy beam onto the target (60); and, an actuator (40) coupled to the focusing element (30) for reversibly translating the focusing element (30) along a scanning path directed substantially parallel to a target plane defined by the target (60). The focused coherent energy beam defines an impingement spot (14) on the target (60). The impingement spot (14) is displaced responsive to the translation of the focusing element (30) along the scanning path. The focus of the coherent energy beam on the target (60) thus remains substantially preserved.

To provide an apparatus and method for forming a thin-film using raw material fluid containing a film ingredient and supercritical fluid or liquid. An apparatus according to the present invention is used for forming a thin-film using raw material fluid containing alcohol, supercritical fluid or liquid carbon dioxide, and a condensation polymer containing an element of a target metal oxide compound. This apparatus includes a substrate holder 2 for retaining a substrate 3, a film-forming chamber 1 for housing the substrate holder, a feeding means for feeding the raw material fluid to the substrate surface, and a lamp heater 4 for heating the substrate 3 retained to the substrate holder 2. Thereby, the thin-film can be formed using the raw material fluid containing a film ingredient and the supercritical fluid or liquid.
Abstract:
A solvent of a resist solution is dropped from a solvent supply nozzle onto the surface of a semiconductor wafer held by a spin chuck. The semiconductor wafer is rotated by the spin chuck to spread the resist solution over the entire surface of the semiconductor wafer W. Simultaneously, the resist solution is dropped from a resist solution supply nozzle onto the semiconductor wafer and spread following the solvent. During the processing, the processing space is isolated from the outer atmosphere by closing a lid of a processing vessel and a sprayed solvent is supplied into the processing space. The processing space is thus filled with the mist of solvent. In the processing space supplied with the solvent, evaporation of the solvent from the resist solution is suppressed. A film of the resist solution is formed with a uniform film thickness to the edge of the semiconductor wafer W.
Abstract:
A system for applying a polyurethane coating to a polyolefin floor tile, comprising a conveyor for moving the floor tile past a plurality of treatment devices, including a solvent applicator, a heater, a plasma generator, an applicator, and an ultraviolet light system. The solvent applicator enables the polymer surface to be more responsive to the processes applied by the heater and plasma generator, increasing the energy of the top surface of the floor tile in preparation for the applicator to apply a liquid polyurethane to the top surface while in the energized state. The ultraviolet light system then exposes the polyurethane to ultraviolet light to at least partially cure it.
Abstract:
The method for electroless deposition of a coating material, which may be a metal, semiconductor, or dielectric, that is carried out at a relatively low temperature of the working solution compensated by an increased temperature on the substrate which is controlled by a heater built into the substrate chuck. A decrease in the temperature of the working solution prevents thermal decomposition of the solution and reduces formation of gas bubbles, normally generated at increased temperatures. Accumulation of bubbles on the surface of the substrate is further prevented due to upwardly-facing orientation of the treated surface of the substrate. The substrate holder is equipped with a substrate heater and a substrate cooler, that can be used alternatingly for quick heating or cooling of the substrate surface.

A chuck assembly for supporting a workpiece within a plasma reactor chamber having sidewalls surrounding an interior region capable of supporting a plasma. The assembly includes a chuck base and at least one support arm extending outwardly from the chuck base perimeter to the chamber sidewalls. The chuck assembly includes a workpiece support member which is supported by one or more vertical translation members arranged between and operatively connected to the chuck base and the workpiece support member.
Abstract:
A cleaning method of removing a vapor-deposition material adhering to equipments without exposure to the atmosphere is provided. A vapor-deposition material adhering to equipments (components of a film-forming apparatus) such as a substrate holder, a vapor-deposition mask, a mask holder, or an adhesion preventing shield provided in a film-forming chamber are subjected to heat treatment. Because of this, the adhering vapor-deposition material is re-sublimated, and removed by exhaust through a vacuum pump. By including such a cleaning method in the steps of manufacturing an electro-optical device, the manufacturing steps are shortened, and an electro-optical device with high reliability can be realized.
Abstract:
An optical disk for recording/reproducing information have the problem of the fine irregularities on its substrate surface that causes increase of noise, under the process of forming the recording layer capable of changing physically or chemically by irradiation of laser light. The problem could deteriorate the record and reproduction characteristics and bring about a defect on a life test or on its storage ability. To solve the problem, the present invention provides the method of manufacturing an optical disk having the pits-and-lands pattern whose organic material is modified by the ultraviolet light irradiation. The transmission of the substrate is not more than 50% at one wavelength in a wavelength region from 300 to 375 nm. And, thereby the surface of an optical disk substrate is smoothed to effect the reduction of the substrate noise and the improvement of record and reproduction characteristics. Moreover, adhesiveness between the substrate and other layer formed thereon is bettered and hence the number of generated defects is reduced.
Abstract:
A process for making bone implants from calcium phosphate powders is disclosed. This process involves selectively fusing layers of calcium powders that have been coated or mixed with polymer binders. The calcium powder mixture may be formed into layers and the polymer fused with a laser. Complex three-dimensional geometrical shapes can be automatically replicated or modified using this approach.
