Abstract
A dividing plate for a thin-film deposition apparatus divides the interior of the vacuum reaction chamber into a plasma discharge space and a film deposition process space, by fixing or connecting a plurality of laminated plates together by securely bonding them over the entire area of their interfacial surfaces, or a large portion thereof.
Claims23
A thin-film deposition apparatus, comprising:
- a vacuum reaction chamber and a dividing plate, the vacuum reaction chamber is divided by the dividing plate into a plasma discharge space and a film deposition process space, the dividing plate having internal spaces and a plurality of holes therein, the internal spaces are separated from said plasma discharge space and the internal spaces are connected with the film deposition process space, the plurality of holes connect the plasma discharge space with the film deposition process space, and a plasma is used to generate radicals in the plasma discharge space, which radicals are introduced into the said film deposition process space through the plurality of holes in the dividing plate, and a precursor gas is directly introduced into the film deposition process space from the internal spaces, whereby the radicals and precursor gas introduced into the film deposition process space react together to deposit a film on a substrate disposed in the film deposition process space,
- the dividing plate is made of a plurality of laminated plates connected together by securely bonding them over substantially an entire area of their interfacial surfaces.
A thin-film deposition apparatus, comprising:
- a vacuum reaction chamber;
- and
- a dividing plate separating the vacuum reaction chamber into a plasma discharge space and a film deposition space;
- the dividing plate includes a plurality of plates laminated together at their interfacial surfaces and having a plurality of internal spaces that are connected to the film deposition space, the dividing plate further having a plurality of holes that connect the plasma discharge space to the film deposition space, and which plurality of holes are distinct from the plurality of internal spaces;
- wherein the plurality of plates are bonded together over a sufficiently large portion of the interfacial surfaces so as to prevent radicals passing through the plurality of holes from passing between any of the plurality of plates into any of the internal spaces, wherein the plurality of plates are bonded together at an outer periphery thereof and in at least some portions of the laminated plates that are within the outer periphery.
A dividing plate for a thin-film deposition chamber having a vacuum reaction chamber that includes a plasma discharge space and film deposition space, the dividing plate comprising:
- a plurality of plates laminated together at their interfacial surfaces;
- a plurality of internal spaces within the dividing plate, the internal spaces being connected to the film deposition space;
- and
- a plurality of holes extending through the dividing plates so as to connect the plasma discharge space and the film deposition space, the plurality of holes being distinct from the plurality of internal spaces;
- wherein the plurality of plates are bonded together over a sufficiently large portion of the interfacial surfaces so as to prevent radicals passing through the plurality of holes from passing between any of the plurality of plates into any of the internal spaces, wherein the plurality of plates are bonded together at an outer periphery thereof and in at least some portions of the laminated plates that are within the outer periphery.
A thin-film deposition apparatus, comprising:
- a vacuum reaction chamber;
- means for dividing the vacuum reaction chamber into a plasma discharge space and a film deposition space;
- the dividing means includes a plurality of internal spaces for retaining a precursor gas, said plurality of spaces being connected to the film deposition space;
- the dividing means further including means, distinct from the plurality of internal spaces, for communicating radicals from the plasma discharge space to the film deposition space;
- the dividing means including a plurality of plates bonded together over a sufficiently large portion of their interfacial surfaces so as to prevent radicals passing through the communicating means from passing between any of the plurality of plates into any of the internal spaces.
