Abstract:
The present invention generally provides a method for preparing an oxynitride film on a substrate. A surface of the substrate is exposed to oxygen radicals formed by ultraviolet (UV) radiation induced dissociation of a first process gas comprising at least one molecular composition comprising oxygen to form an oxide film on the surface. The oxide film is exposed to nitrogen radicals formed by plasma induced dissociation of a second process gas comprising at least one molecular composition comprising nitrogen using plasma based on microwave irradiation via a plane antenna member having a plurality of slits to nitridate the oxide film and form the oxynitride film.

Abstract:
A method for preparing an interfacial layer for a high-k dielectric layer on a substrate. A surface of said substrate is exposed to oxygen radicals formed by ultraviolet (UV) radiation induced dissociation of a first process gas comprising at least one molecular composition comprising oxygen to form an oxide film. The oxide film is exposed to nitrogen radicals formed by plasma induced dissociation of a second process gas comprising at least one molecular composition comprising nitrogen to nitridate the oxide film to form the interfacial layer. A high-k dielectric layer is formed on said interfacial layer.
Abstract:
A method to solve such a problem that plasma will not ignite in restarting operation of a processing container that has not been operated with the inside kept drawn to vacuum. Gas containing oxygen is passed in a processing container (21), and ultraviolet light is irradiated to the gas while gas inside the processing container (21) is being discharged. After that, a remote plasma source (26) is driven to ignite plasma.
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:
It is intended to efficiently nitride an extremely thin oxide film or oxonitride film of 0.4 nm or less thickness while minimizing a film increase. In particular, oxygen radicals are generated through oxygen radical generating mechanism so as to oxidize a silicon substrate with the generated oxygen radicals, thereby forming an oxide film on the silicon substrate, and further nitrogen radicals are generated through nitrogen radical generating mechanism so as to nitride the surface of the oxide film, thereby forming an oxonitride film.
Abstract:
This method for film formation has a first step of forming a first insulation film, the essential component of which is a material having a first dielectric constant, on the surface of a semiconductor substrate and a second step of forming a second insulation film, the essential component of which is a material having a second dielectric constant larger than the first dielectric constant, on the first insulation film to be thicker than this first insulation film. Since the process of forming a film of a high dielectric constant material that constitutes the second insulation film is executed successively, following the formation of a barrier layer that is the first insulation film, it is possible to form a gate of a high dielectric constant material stable to the substrate.
