摘要： Provided are a CIGS solar cell and a method of fabricating the CIGS solar cell. In the method, a buffer layer exposing protrusions is formed. Then, a window electrode layer having an uneven surface conforming with the protrusions of the buffer layer is formed. Thus, an additional process for making the upper surface of a window electrode layer rough is unnecessary in order to decrease surface reflectance of incident sunlight and increase the solar cell efficiency, so that productivity can be improved.

摘要： The present invention relates to a method of fabricating vertical-cavity surface emitting lasers being watched as a light source for long wavelength communication. The present invention includes forming a layer having a high resistance near the surface by implanting heavy ions such as silicon (Si), so that the minimum current injection diameter is made very smaller unlike implantation of a proton. Further, the present invention includes regrowing crystal so that current can flow the epi surface in parallel to significantly reduce the resistance up to the current injection part formed by silicon (Si) ions. Therefore, the present invention can not only effectively reduce the current injection diameter but also significantly reduce the resistance of a device to reduce generation of a heat. Further, the present invention can further improve dispersion of a heat using InP upon regrowth and thus improve the entire performance of the device.

摘要： Provided is a method of fabricating a vertical cavity surface emitting laser among semiconductor optical devices, comprising: bonding a dielectric mirror layer to an epi-structure having a mirror layer and an active layer; bonding these on a new substrate using a metal bonded method; removing the existing substrate; and fabricating a vertical cavity surface emitting laser on the new substrate. The method of fabricating the vertical cavity surface emitting laser is performed by moving and attaching a vertical cavity surface emitting laser to a new substrate using an external metallic bonding method, without electrically and optically affecting upper and lower mirrors and an active layer that constitutes the vertical cavity surface emitting laser. While using the existing method of fabricating the vertical cavity surface emitting laser, the VCSEL is fabricated by moving to a new substrate having good thermal characteristics so that good heat emission characteristics are accomplished, thus facilitating manufacture of the vertical cavity surface emitting laser having high reliability and good characteristics.
