Patent ID: 7692782

Claim:
Method for fabricating several Haze noise standards which comprise an insulating thin layer and a plurality of nano-structures which respectively have a hemi-spherical or convex bump shape and which are regularly distributed over the insulating layer comprising the fabrication of at least one first standard and at least one second standard respectively, by a method comprising: a) the formation on at least one insulating layer of seeds made of a first semi-conducting material by chemical deposition from a first precursor gas for the first semi-conductor material, b) formation on the insulating layer of nano-structures based on a second semi-conductor material, from stable seeds of the first semi-conductor material by chemical deposition from a second precursor gas for the second semi-conductor material, wherein the first standard and the second standard have equal densities of nano-structures, with the first standard comprising nano-structures of a first size or associated with a first range of sizes and with the second standard comprising nano-structures of a second size which is different from the first size or associated with a range of sizes which is different from the first range.
