  • Patent number: 7465592
    Abstract: The invention provides a reliable way to fabricate a new vertical structure compound semiconductor device with improved light output and a laser lift-off processes for mass production of GaN-based compound semiconductor devices. A theme of the invention is employing direct metal support substrate deposition prior to the LLO by an electro-plating method to form an n-side top vertical structure. In addition, an ITO DBR layer is employed right next to a p-contact layer to enhance the light output by higher reflectivity. A perforated metal wafer carrier is also used for wafer bonding for easy handling and de-bonding. A new fabrication process is more reliable compared to the conventional LLO-based vertical device fabrication. Light output of the new vertical device having n-side up structure is increased 2 or 3 times higher than that of the lateral device fabricated with same GaN/InGaN epitaxial films.
