A vertical cavity surface emitting laser (VCSEL) is provided with an aperture for guiding a flow of electric currents. The aperture is defined by an oxide so that the aperture is formed to be substantially circular in shape. A method for fabricating the laser is also disclosed. The structure of the (VCSEL) makes it possible to control the oxidation rates of an oxidable layer in which an aperture is formed for guiding the flow of electric currents of a VCSEL, by forming a mesa trench of the VCSEL in a segmented structure which has a predetermined number of segments. Accordingly, it is possible to form an aperture approximately in a circular shape, so that the light emitting angle and shape of the VCSEL are easily controlled.

Disclosed is a land grid array module comprising: a substrate; a plurality of active and passive components mounted on both sides of the substrate; and a molding compound for encapsulating the both sides of the substrate with the active and passive components mounted thereon. The land grid array module mounts the passive and active components on both sides of the substrate, thereby improving the integration of the circuit device. Also, the use of a thin film printed circuit board or a flexible printed circuit board with high rigidity as the substrate reduces the overall thickness of the land grid array module.
