Abstract:
1. A semiconductor device comprising: a first substrate including first, second and third layers; and a second substrate including fourth to sixth layers; wherein the first substrate provides an electric device, wherein the second substrate provides a physical quantity sensor, wherein the first layer of the first substrate is a shield for protecting the electric device and the physical quantity sensor, wherein the second layer of the first substrate is an insulation layer so that the first substrate is provided by a silicon-on-insulator substrate, wherein the sixth layer of the second substrate faces the third layer of the first substrate, wherein the physical quantity sensor includes a movable portion, which is provided by the sixth layer of the second substrate so that the movable portion is sandwiched by the first and second substrates, wherein the second substrate further includes a second loop layer, which surrounds the movable portion, and wherein the second loop layer is electrically connected to the third layer of the first substrate with a loop bump so that the movable portion is shielded.
