Abstract
A semiconductor device includes a substrate, a semiconductor chip for emitting light, and a reflector enclosing the semiconductor chip for reflecting the light emitted from the semiconductor chip. The substrate is provided with a first electrode and a second electrode each electrically connected with the semiconductor chip. A transverse cross-section of the reflector defines an elongated figure, such as oblong, elliptical, rhombic or rectangular.
