A chip scale chip card (CSC) mainly includes a chip carrier having a plurality of external contact fingers and a cavity, at least a micro electronic element, a first chip, a second chip, and an encapsulant. The micro electronic element is embedded in the cavity. The first and second chips are disposed on the carrier. Therein, the chip card has a contact surface from which the external contact fingers are exposed. The cavity for accommodating the micro electronic element is included in chip bond area of the first chip such that the area of the contact surface is between 1.0~1.5 times of that of the active surface of the chip. The chip card will be of chip scale and stack more chips.
