Abstract
A method of forming a multilayer structure for a pixelated display and a multilayer structure for a pixelated display is provided. The method comprising providing a first wafer comprising first layers disposed over a first substrate, said first layers comprising non-silicon based semiconductor material for forming p-n junction LEDs (light emitting devices); providing a second partially processed wafer comprising silicon-based CMOS (Complementary Metal Oxide Semiconductor) devices formed in second layers disposed over a second substrate, said CMOS devices for controlling the LEDs; and bonding the first and second wafers to form a composite wafer via a double-bonding transfer process.
