Appeal No. 2004-2148
Application No. 09/362,397
Appellant’s invention is directed to a method for producing a
information carrier comprising at least two solid material interfaces. The
method comprises depositing a layer, which at least predominantly
consists of SivNw or SivNwHu, by means of a reactive vacuum coating
process. According to Appellant, the claimed is particularly suited for
producing the intermediate layer of the information carrier. Claims 91, 92
and 107, which are representative of the claimed invention, appear below:
91. A method for producing an information carrier comprising
at least two solid material interfaces adapted to contain
information and whereat the information is stored by local
modulation of at least one solid material characteristic, from
which characteristic reflection of electromagnetic radiation
depends at said interface, further comprising at least one
intermediate layer between said two solid material interfaces,
said at least one intermediate layer transmitting said radiation,
said information being readable from at least one of said solid
material interfaces by means of radiation of predetermined
wavelength, the method comprising the step of:
depositing in said intermediate layer at least one layer
at least predominantly comprising SivNw by means of a
reactive vacuum coating process, comprising the step of
freeing Si from a solid body into a process atmosphere with a
reactive gas containing N.
92. A method for producing an information carrier comprising
at Ieast two solid material interfaces adapted to contain
information and whereat the information is stored by local
modulation of at least one solid material characteristic, from
which characteristic reflection of electro-magnetic radiation
