Title
(EN) SUBSTRATE HAVING AN OPTICALLY TRANSPARENT EMI/RFI SHIELD
(FR) SUBSTRAT A BLINDAGE CONTRE LES INTERFERENCES ELECTROMAGNETIQUES ET DES RADIOFREQUENCES OPTIQUEMENT TRANSPARENT
Abstract
(EN)
A substrate having an optically transparent EMI/RFI shield (30). A transparent substrate has a thin film metallization pattern (20) on one surface, and some of the pattern (20) is covered with an optically transparent EMI/RFI shield (30). The shield (30) comprises a vapor deposited layer of indium-tin oxide on the substrate surface and on the metallization pattern (20). The indium-tin oxide is optically transparent. It is patterned to expose one portion (34) of the metallization pattern (20) and to cover a second portion (32) of the metallization pattern (20). The shield (30) is electrically connected to a part of the metallization pattern (20) that is covered (32), thus providing electrical shielding and transparency.

L'invention concerne un substrat présentant un blindage (30) contre les interférences électromagnétiques et des radiofréquences, optiquement transparent. Ce substrat transparent présente un réseau d'interconnexions (20) en couche mince sur une surface et une partie du réseau (20) est couverte par un blindage (30) contre les interférences électromagnétiques et des radiofréquences, optiquement transparent. Le blindage (30) comporte une couche d'indium - oxyde d'étain obtenue par dépôt en phase vapeur sur la surface du substrat et sur le réseau d'interconnexions (20). La couche d'indium - oxyde d'étain est optiquement transparente. Elle forme un motif laissant découverte une partie (34) du réseau d'interconnexions (20) et couvrant une seconde partie (32) du réseau d'interconnexions (20). Le blindage (30) est connecté électriquement à une partie du réseau d'interconnexions (20) qui est couverte (32), ce qui assure le blindage électrique et la transparence.
