摘要:
A semiconductor wafer processing apparatus comprises a reaction furnace capable of heating inside thereof, a wafer mount for mounting a semiconductor wafer thereon and a transfer device. The wafermount includes an opening which is greater than the semiconductor wafer and which has a circle shape or a shape substantially similar to an outer periphery of the semiconductor wafer, and includes a wafer supporting portion projecting inwardly of the opening for supporting the semiconductor wafer. The transfer device is capable of holding the wafer mount outside the semiconductor wafer as viewed from a vertical direction, and transferring the wafer mount carrying the semiconductor wafer thereon substantially horizontally into and/or out from the reaction furnace.
摘要:
A method of manufacturing a semiconductor device. In the method, an aluminum-containing insulation film is formed on an electrode film of a substrate by alternately repeating a process of supplying an aluminum precursor into a processing chamber in which the substrate is accommodated and exhausting the aluminum precursor from the processing chamber and a process of supplying an oxidizing or nitriding precursor into the processing chamber and exhausting the oxidizing or nitriding precursor from the processing chamber; and a high permittivity insulation film different from the aluminum-containing insulation film is formed on the aluminum-containing insulation film by alternately repeating a process of supplying a precursor into the processing chamber and exhausting the precursor from the processing chamber and a process of supplying an oxidizing precursor into the processing chamber and exhausting the oxidizing precursor from the processing chamber. In addition, heat treatment is performed on the substrate.

In a MIS transistor of which gate length is 10 nm or less, a gate insulator comprising a silicon oxide film formed on a silicon substrate and a high-k film formed on the silicon oxide film has a nitrided region including more nitrogen at the lateral side than at the central side in the gate-length direction, and including more nitrogen at the upper side than at the lower side in the film thickness direction. The reliability and characteristics of a MIS transistor using a gate insulator including a high-k (high dielectric constant) film is enhanced.

摘要:
The intensity of the light emitted from the light-emitting diode on wafer is measured and then the potential difference between the terminals of the light-emitting element, and the plasma current flowing thereinto are derived from measured light intensity. Since the use of a camera enables non-contact measurement of emitted light intensity, the lead-in terminals for lead wires that are always required in conventional probing methods become unnecessary. In addition, since the target wafer does not require lead wire connection, wafers can be changed in the same way as performed for etching.
摘要:
A plasma treatment method and apparatus utilize various gas inlet and outlet structure arrangements to optimize treatment characteristics for a semiconductor wafer. A buffer zone is created between gas inlets and the discharge zone of the vacuum treatment chamber to enhance uniformity of gas flow. The evacuation arrangement enables reactant gas to be exhausted uniformly to reduce gas residence time below a threshold while maintaining optimum flow rates and etch uniformity at low effective exhaust speeds.

A base insulating film containing hafnium and oxygen is formed on a silicon oxide (SiO2) film formed on a main surface of a substrate. Subsequently, a metal thin film thinner than the base insulating film and made of only a metal element is formed on the base insulating film, and a protective film having humidity resistance and oxidation resistance is formed on the metal thin film. Then, by diffusing the entire metal element of the metal thin film into the base insulating film in a state of having the protective film, a mixed film (high dielectric constant film) thicker than the silicon oxide film and having a higher dielectric constant than silicon oxide and containing hafnium and oxygen of the base insulating film and the metal element of the metal thin film is formed on the silicon oxide film.
