Abstract

E' descritta una struttura comprendente una lastrina metallica (12), una piastrina di materiale semiconduttore, o "chip", (13) fissata sulla lastrina (12), reofori terminali (11), fili di interconnessiorie (18) tra reofori (11) e aree metallizzate (17) del "chip" (13) e un corpo di materia plastica (10) che ingloba il tutto ad eccezione di una superficie della lastrina (12) e di parte del reofori (11). Per ottenere una migliore aderenza tra plastica e metallo, aree prefissate (30, 32, 33) della lastrina (12) e dei reofori (11) presentano una rugosità superiore a 1 (Ra=1 um).
