Abstract
An object including at least one graphic element, including at least one at least partly transparent substrate, at least one face of which includes recesses forming a pattern of the graphic element filled with the at least one material, the face of the substrate being fixed to at least one face of at least one support by wafer bonding, the substrate and the support forming a monolithic structure.
Claims12
An object comprising:
- at least one at least partly transparent substrate having a thickness less than or equal to 10 μm or between 100 μm and 1 mm, at least one face of which comprises recesses forming a pattern of a graphic element completely filled with at least one material having a thickness between 50 nm and 100 nm,
- the at least one face of the at least one at least partly transparent substrate comprising the recesses being fixed to at least one face of at least one support by molecular adhesion, the at least one at least partly transparent substrate and the at least one support forming a monolithic structure in which the graphic element is hermetically sealed,
- a roughness of surfaces bonded by molecular adhesions is less than about 1 nm, and
- an adherence material in a recess between the at least one material and the at least one at least partly transparent substrate.
