摘要:
A plasma operation apparatus utilizes plasma generated by a microwave cooperative with a magnetic field as to perform a surface operation on a specimen such as semiconductor substrates, such as, for example, thin film deposition, etching, sputtering and plasma oxidation. The apparatus particularly takes advantage of electron cyclotron resonance and is suitable for performing highly efficient and high-quality plasma operations.

A plasma treatment apparatus for forming a thin film on a substrate in a vacuum vessel includes a magnetic field generator which can be positioned inside or outside the vacuum vessel, and a microwave source. The magnetic field strength is controllable such that an electron cyclotron resonance (ECR) area is defined near the substrate. The magnetic field generator can be arranged so that plasma and reactive gas introduction ports are on the microwave introduction side of the ECR area and the substrate is on the opposite side of the ECR area. Alternatively, a gas introduction port can be positioned such that reactive gas is introduced into the ECR area or onto the substrate.

The present invention relates to a plasma treatment apparatus for making plasma surface processing of a specimen such as thin-film formation, etching, sputtering or plasma oxidation by use of plasma produced through microwave discharge. In a specimen chamber provided with a specimen table for holding at least one specimen thereon, a microwave is introduced from a direction intersecting a magnetic line of force so as to propagate in the longitudinal direction of an ECR region or in a direction along the plane of the ECR region. Since the microwave is introduced from the transverse direction of the specimen chamber, the provision of a microwave introducing window at an upper portion of the specimen chamber is not required and hence a counter electrode for applying an electric field to the specimen can be disposed at the upper portion of the specimen chamber, thereby making it possible to apply a uniform electric field to the specimen so that the specimen is subjected to a uniform treatment.

The present invention relates to a microwave plasma processing apparatus for processing such as thin film formation, etching, sputtering, and plasma oxidation, etc., on a surface of a processing object by utilizing a high density plasma generated by electron cyclotron resonance. A vacuum vessel of the apparatus, in which a microwave transmitted by a microwave guide is utilized for converting gas supplied to the vacuum vessel to plasma for the plasma processing of the processing object placed in the vacuum vessel, is formed in, such manner that the interior space of the vacuum vessel extends beyond the outer periphery of magnetic field generating coils, and the extended portion of the vessel is provided with a gas outlet for connection with an evacuation apparatus to evacuate the interior of the vacuum vessel to a desired vacuum degree. Accordingly, preferable evacuating characteristics can be obtained even in a case when a large amount of the reaction gas is supplied to the vacuum vessel in order to process a large size processing object, because the vacuum vessel in which the processing object is placed can be connected with the evacuation apparatus through a space and the same effect as if the evacuation apparatus is directly connected with the vacuum vessel is realized.
摘要:
In a plasma processing apparatus which forms a gaseous raw material into a plasma by using electron cyclotron resonance and processes a substrate, leading-edge opening portions of an introduction tube into which a gaseous raw material is introduced are formed in the inner wall surface of the container in such a way that they do not project within the vacuum container. A heater is wound around the introduction pipe so that the opening portions thereof can be heated. With this construction, even if a gaseous raw material which is a liquid or solid at normal temperature and normal pressure is made to flow, the gaseous raw material can be prevented from being liquefied or solidified in the opening portions of the introduction pipe, and the opening portions of the introduction pipe can be prevented from being clogged. In addition, since there are no projections within the vacuum container, the propagation of microwaves is not impeded, making it possible to uniformity process the substrate.

A cover is pivotably attached to a case body. Male thread portions of a multiple thread and unthreaded portions are alternately formed on a peripheral wall of a cosmetic container section of the case body. A ring is rotatably attached to the cover and externally fitted to the peripheral wall. The ring has female thread portions of a multiple thread intermittently formed. The female and male thread portions are engageable and disengageable. An inner cover made of an elastic material is attached to the lower portion of the cover so that the inner cover is brought into press contact with an open edge of the peripheral wall. A space is formed between the cover and the inner cover so that the inner cover is elastically deformed and expanded. When the female and the male thread portions are engaged with each other and the ring is rotated to a closed position, the cover approaches the case body so that the inner cover is brought into press contact with the open edge of the peripheral wall. When the temperature within the cosmetic container section is increased, the inner cover is elastically expanded upwards to increase the volume within the cosmetic container section. Thus, an increase in pressure within the cosmetic container section is suppressed.

A molded resin product includes a substrate made of a transparent resin, opaque coating film disposed on rear surface of the substrate except for an area set aside for a patterned portion, a transparent resin material disposed in the area set aside for the patterned portion on the rear surface of the substrate, and an opaque reflection coating or a half-reflective coating laminated to the transparent resin material. Under this configuration, the patterned portion looks as if it pops up from the rear surface of the substrate. If a half-reflective coating is used, the pattern is visible through the half-reflective coating when the pattern is viewed from the rear surface of the lid of a molded resin product.

Disclosed is a synthetic resin container provided with an inverting, foldback bottom wall that can maintain a stable, self-supporting position while being able to minimize the amount of residual contents, and that can be formed by blow-molding, etc., and maintain the favorable producibility or low cost of the past. The synthetic resin container is provided with a bottom wall that forms the bottom of the container, and a drum section that is united to the perimeter of the bottom wall and forms a filling space M for contents on the inside, and is a synthetic resin container wherein a raised bottom is formed by inverting and folding back said bottom wall toward said drum section. Said drum section has a lower peripheral wall that touches or approaches the outer wall part of said bottom wall and forms a self-supporting base by the inversion and folding back of said bottom wall.
