Semiconductor device, and method and apparatus for manufacturing the same

Disclosed is a semiconductor device including an organic material substrate, a semiconductor chip flip chip connected to substantially a center of one surface of the organic material substrate, and a semiconductor package mounted on another surface of the organic material substrate in a manner to avoid a position opposing to the flip chip connected semiconductor chip. Additionally, disclosed is a semiconductor device including an organic material substrate, a semiconductor chip flip chip connected to substantially a center of one surface of the organic material substrate, and a semiconductor package having a connection terminal and mounted on another surface of the organic material substrate via the connection terminal in a manner that an overlap with the flip chip connected semiconductor chip occurs, at least a part of the connection terminal in the overlap being a dummy terminal not used for transmission of an electric signal.

Semiconductor device

A non-contact IC card comprises: a substantially rectangular insulating substrate; a semiconductor chip mounted on a first face of the insulating substrate; and an antenna coil for transmitting information and for enhancing the mechanical strength of the insulating substrate, the antenna coil being arranged on the first face of the insulating substrate along the outer periphery of the first face, and the antenna coil having first and second connecting terminals which are connected to the semiconductor chip. Thus, it is possible to provide a non-contact IC card capable of enhancing the connection reliability of an IC chip mounting portion, maintaining communication characteristics, and maintaining a high mechanical strength.

Non-contact IC card and IC card communication system

A semiconductor chip having a plurality of electrodes on its surface is fixed onto a die pad. The leads are spaced away from the die pad and connected to the electrodes of the semiconductor chip by means of a TAB tape. The die pad is substantially equal in size to the insulation film of the TAB tape. The die pad has a plurality of resin circulating holes around the semiconductor chip. The resin circulating holes are arranged such that a fluid resin sufficiently flows into a narrow area between the TAB tape and die pad. On the die pad, portions each between adjacent resin circulating holes serves as heat conducting paths. The heat generated from the semiconductor chip is transmitted to the entire region of the die pad through the heat conducting paths and then radiated outside.
