Definitions
- MATERIAL INCLUDING A ZINC-BASED FINE DOXIDE DIELECTRIC UNDERLAYMENT STACK AND PROCESS FOR DEPOSITING THIS MATERIAL
- the invention relates to a material comprising a glass substrate coated on one face with a stack of thin layers with reflection properties in the infrared and / or in the solar radiation comprising at least one metallic functional layer, in particular based on silver or a metal alloy containing silver and at least two anti-reflection coatings, said anti-reflection coatings each comprising at least one dielectric layer, said functional layer being disposed between the two anti-reflection coatings.
- the single, or each, metallic functional layer is thus placed between two antireflection coatings each generally comprising several layers which are each made of a dielectric material of the nitride type, and in particular silicon nitride or silicon nitride. aluminum, or oxide. From an optical point of view, the purpose of these coatings which surround the or each metallic functional layer is to "antireflect" this metallic functional layer.
- this radiation treatment of the stack does not structurally modify the substrate.
- the invention is based on the discovery of a particular configuration of layers surrounding a metallic functional layer which makes it possible to reduce the resistance per square at the same functional layer thickness, or even to reduce the functional layer thickness in order to obtain improved thermal properties, and this after a heat treatment of the material or a radiation treatment of the stack according to known techniques.
- An aim of the invention is thus to achieve the development of a new type of stack of layers with one or more functional layers, a stack which has, after heat treatment of the material or treatment of the stack with radiation, a low resistance per square (and therefore low emissivity), high light transmission, as well as uniformity of appearance, both in transmission and in reflection.
- the subject of the invention is thus, in its broadest sense, a material according to claim 1.
- This material comprises a glass substrate coated on one face with a stack of thin layers with reflection properties in the infrared and / or in the solar radiation comprising at least one metallic functional layer, in particular based on silver or metal alloy containing silver and at least two anti-reflection coatings, said anti-reflection coatings each comprising at least one dielectric layer, said functional layer being arranged between the two anti-reflection coatings, said material being remarkable:
- said anti-reflective coating located under said functional layer towards said substrate comprises:
- a zinc ZnO-based oxide sublayer which is located under and in contact with said functional layer, with a physical thickness of said ZnO zinc oxide-based sublayer which is between 0.3 and 5.0 nm, or even between 0.3 and 4.4 nm, or even between 0.3 and 2.9 nm, or even between 0.5 and 2.4 nm;
- a dielectric sub-layer of silicon-zirconium nitride Si x N y Zrz which is located under and in contact with said sub-layer of oxide based on zinc ZnO, with a physical thickness of said sub-layer of silicon-zirconium nitride Si x N y Zrz which is between 5.0 and 50.0 nm, or even between 10.0 and 40.0 nm, or even between 15.0 and 25.0 nm;
- a primary dielectric sub-layer of silicon-based nitride S1 3 N 4 which is located under and in contact with said sub-layer of silicon-based nitride; zirconium Si x N y Zrz, with a physical thickness of said primary dielectric sublayer of silicon-based nitride S1 3 N 4 which is between 5.0 and 50.0 nm, or even between 10.0 and 40.0 nm, or even between 15.0 and 20.0 nm;
- said anti-reflective coating located above said functional layer opposite said substrate comprises:
- a zinc-based oxide overlayer ZnO which is located on and in contact with said functional layer, with a physical thickness of said zinc-based oxide ZnO overlayer which is between 2.0 and 10.0 nm or even between 2.0 and 8.0 nm, or even between 2.5 and 5.4 nm; and a dielectric overlayer which is located on said zinc-based oxide overlayer ZnO and, preferably a silicon-based nitride dielectric overlayer, S13N 4 .
- Said zinc-based oxide sublayer is the very thin layer mentioned above: it has a thickness corresponding to a minimum of a mono-molecular layer of ZniOi and a maximum thickness of only a few nanometers.
- the zinc oxide is neither substoichiometric nor superstoichiometric, in order to have the lowest possible absorption coefficient in the visible range.
- Said primary silicon nitride dielectric sublayer is a barrier layer which prevents the penetration of elements from the substrate towards the metallic functional layer during processing.
- Said stack may comprise a single metallic functional layer or may comprise two metallic functional layers, or three metallic functional layers, or four metallic functional layers; the metallic functional layers here are continuous layers.
- each functional layer is according to the previous indication, with: - on the one hand, said antireflection coating located under and in contact with each functional layer which comprises, in the direction of said substrate:
- a zinc ZnO-based oxide sublayer which is located under and in contact with said functional layer, with a physical thickness of said sublayer layer based on zinc oxide ZnO which is between 0.3 and 5.0 nm, or even between 0.3 and 4.4 nm, or even between 0.3 and 2.9 nm, or even between 0.5 and 2.4 nm;
- a dielectric sub-layer of silicon-zirconium nitride Si x N y Zrz which is located under and in contact with said sub-layer of oxide based on zinc ZnO, with a physical thickness of said sub-layer of silicon-zirconium nitride Si x N y Zrz which is between 5.0 and 50.0 nm, or even between 10.0 and 40.0 nm, or even between 15.0 and 25.0 nm;
- a primary dielectric sub-layer of silicon-based nitride S1 3 N 4 which is located under and in contact with said sub-layer of silicon-zirconium nitride Si x N y Zrz, with a physical thickness of said sub primary dielectric layer of silicon-based nitride S1 3 N 4 which is between 5.0 and 50.0 nm, or even between 10.0 and 40.0 nm, or even between 15.0 and 20.0 nm;
- said anti-reflective coating located above and in contact with each functional layer, on the opposite side of said substrate: - an oxide overlay based on zinc ZnO which is located on and in contact with said functional layer, with a physical thickness of said zinc-based oxide ZnO overlay which is between 2.0 and 10.0 nm, or even between 2.0 and 8.0 nm, or even between 2.5 and 5.4 nm; and
- a dielectric overlay which is located on said overlay of zinc based oxide ZnO and, preferably, a dielectric overlay of silicon based nitride, S13N4.
