                The corporation's main

                 business content is 

                power semiconductor 


                The products mainly 

                include bipolar trans

                istors, MOS-type field-

                effect transistors and 

                diodes, which are wi

                dely used in electron

                ic lighting, green 

                power supplies, auto

                motive electronics 

                and other fields.
