    • A method for fabricating a self aligned three dimensional transistor is provided to limit the height of a gate by using a mask layer as a planarization stop layer in a planarization process. A mask having a shape of a source forming area, a drain forming area, and a channel forming area is formed on a substrate including a silicon layer on a first insulating layer. The silicon layer is patterned by the mask. The mask is etched on the channel forming area. An undercut is formed in the lower part of the channel forming area. A nano wire channel(118) is formed by thermally oxidizing the channel forming area. A gate oxide layer(160) is formed on the nano wire channel. A gate material covering the mask is deposited on the substrate. A gate is formed by planarizing the gate material using the mask as a CMP stop layer. The mask is removed. A source(115') and a drain(117') are formed by irradiating the impurity from the substrate.

    • An electrically-pumped high power vertical cavity surface emitting laser is provided to obtain a high output in single mode by distributing uniformly carriers. An electrically-pumped high power vertical cavity surface emitting laser includes a first DBR mirror(20), an active layer(30) formed on the first DBR mirror, a second DBR mirror(40) formed on the active layer, and a capping layer(70) formed on the second DBR mirror. The second DBR mirror includes low refractive layers(41) of n number, a high refractive layer(43) inserted between the low refractive layers, and a carrier spreading layer inserted between the low refractive layers and the high refractive layer in order to distribute uniformly carriers.
