Abstract
An electronic device includes a carrier substrate with at least one electronic-circuit chip mounted on a front face of the carrier substrate. An encapsulation block on the front face and embedding the electronic-circuit chip has a periphery with corners. The encapsulating block further has, in at least one local zone located in at least one corner and from the front face of the carrier substrate, a smaller thickness than a thickness of the encapsulation block at least in a surrounding zone. The electronic device is manufactured by a process in which the zone of smaller thickness is obtained by molding or by machining.
