Patent ID: 8864489

Claim:
A heating mould for thermal nanoimprint lithography comprising: a substrate having a first principal surface and a second principal surface, and a through-cavity extending from a first orifice in the first principal surface up to a second orifice in the second principal surface, said second orifice being completely closed off by a first membrane, which is an electrically and thermally insulating membrane, with a first side disposed in contact with said second principal surface and at least partially covering said second principal surface; heating means disposed on a second side of said first membrane in a zone of said first membrane above said second orifice; an electrically and thermally insulating layer which covers said heating means and, at least partially, said first membrane; imprint patterns disposed on said electrically and thermally insulating layer in a zone of said electrically and thermally insulating layer above said second orifice; and means for supplying an electric current to said heating means.
