Disclosed herein is a fanless high-efficiency cooling device that is applicable to electronic products having heat sources, such as plasma display panel (PDP) televisions, liquid crystal display (LCD) televisions, and liquid crystal display (LCD) monitors. The fanless high-efficiency cooling device using ion wind comprises a heat sink having a fixing part fixedly attached to a heat-generating part of an electronic product and a plurality of protrusions extending a predetermined height from a bottom surface of the fixing part, a cover that covers the upper part of the heat sink, at least one electric wire for generating ion wind between the corresponding protrusions when high voltage is applied to the electric wire, an electric wire-supporting member that supports both ends of the electric wire, and a power supply that connects a high-voltage terminal to the electric wire and connects a ground terminal to the heat sink to supply high voltage to the electric wire.

Disclosed is a submount integrated photodiode package with an improved metal layer configuration and laser diode package using the same. In particular, a unitary laser diode of the invention provides a light receiving area overlying a semiconductor substrate to correspond to a radiation area of light emitted from a laser diode so as to reduce chip size in respect to a conventional one while maintaining a monitoring current identical to the conventional one as well as improve heat-radiating features. The invention provides a unitary laser diode package which comprises a light receiving area overlying a semiconductor substrate and having the same configuration as a radiation area of emission light from the laser diode and a metal layer adjacent to the light receiving area.
