Abstract

The present invention relates to a semiconductor package having at least one first layer chip, a plurality of first metal bumps, at least one second layer chip and a package body. The first layer chip includes a first active surface upon which the first metal bumps are disposed and a plurality of first signal coupling pads disposed adjacent to the first active surface. The second layer chip is electrically connected to the first layer chip, and includes a second active surface that faces the first active surface and a plurality of second signal coupling pads. The second signal coupling pads are capacitively coupled to the first signal coupling pads so as to provide proximity communication between the first layer chip and the second layer chip. The package body encapsulates the first layer chip, the first metal bumps, and the second layer chip, and the first metal bumps are partially exposed.
