Patent ID: 8259453

Claim:
A card device comprising: a semiconductor package section having memory functions; and a substrate section superposed on and joined to said semiconductor package section at a superposition junction and having a variety of electronic components mounted thereon, wherein, (a) said semiconductor package section includes (1) a card-side connector section having card-side terminals for inputting and outputting information signals created on a surface on which a junction between said substrate section and said semiconductor package section is formed, (2) package-side terminals at a location at which said semiconductor package section is joined to said substrate section, and (b) said substrate section includes substrate-side terminals at a location at which said substrate section is connected to said semiconductor package section, said substrate section being electrically joined to said semiconductor package section by making use of said package-side terminals and said substrate-side terminals, and said superposition junction between said semiconductor package section and said substrate section being provided with such an offset that said card-side connector protrudes out off said card device.
