Electronic device and method for producing the same

A method for producing an electronic device having a drive circuit comprising a solar cell structure, the method comprising the steps of:

• providing a first wafer having a plurality of independent solar cell structures comprising a compound semiconductor, the solar cell structures being formed on a starting substrate by epitaxial growth, and a second wafer having a plurality of independent drive circuits formed, so that either one of the first wafer or the second wafer has a plurality of independent diode circuits and capacitor-function laminated portions;
• obtaining a bonded wafer by bonding the first wafer and the second wafer so that the plurality of solar cell structures, the plurality of diode circuits, the plurality of capacitor-function laminated portions, and the plurality of drive circuits are respectively superimposed;
• wiring the bonded wafer so that electric power can be supplied from the plurality of solar cell structures to the plurality of diode circuits, the plurality of capacitor-function laminated portions, and the plurality of drive circuits respectively;
• and
• producing an electronic device having the drive circuit comprising the solar cell structure by dicing the bonded wafer.
