Patent

CA 2381403

An aluminum nitride sintered body free from crack, having a via hole and a good appearance, and prepared by sintering an aluminum nitride formed body having a through hole for making a via hole with high insolubility and sufficiently densifying the sintered body. One or more through holes for making dummy via holes not used for electrical connection are made around a through hole for making a via hole with high isolability. A conductive paste is placed also in the through holes for making dummy via holes. The aluminum nitride formed body is sintered.

L'invention concerne un corps fritté en nitrure d'aluminium exempt de criques présentant un trou d'interconnexion et étant de bon aspect, obtenu par frittage d'un corps à base de nitrure d'aluminium qui présente un trou de passage pour pratiquer un trou d'interconnexion hautement insoluble et par densification suffisante du corps fritté. Un ou plusieurs trous de passage prévus pour pratiquer de faux trous d'interconnexion qui ne sont pas utilisés à des fins de connexion électrique sont pratiqués autour d'un trou de passage prévu pour effectuer un trou d'interconnexion hautement insoluble. Une pâte conductrice est également placée dans les trous de passage pour former de faux trous d'interconnexion. Le corps en nitrure d'aluminium formé est fritté.
