Patent ID: 8368216

Claim:
A semiconductor package, comprising: at least one first layer chip, comprising: a first active surface; and a plurality of first signal coupling pads, disposed adjacent to the first active surface; a plurality of first metal bumps, disposed on the first active surface of the first layer chip; at least one second layer chip, disposed on the first active surface and electrically connected to the first layer chip, comprising: a second active surface, facing the first active surface of the first layer chip; and a plurality of second signal coupling pads, disposed adjacent to the second active surface, and capacitively coupled to the first signal coupling pads of the first layer chip, so as to provide proximity communication between the first layer chip and the second layer chip; and a package body, encapsulating the first layer chip, the first metal bumps and the second layer chip, wherein each of the first metal bumps has at least a portion exposed from the package body.
