A MULTI-LAYER SEMICONDUCTOR DEVICE HAVING LASER DEVICES, AND A MANUFACTURING METHOD FOR IT

摘要

A multi-layer semiconductor device having laser devices and a manufacturing method thereof are provided to implement semiconductor discrete device and the laser devices on a single chip by transmitting electrical signals of the semiconductor discrete devices to the laser devices through wiring inside the chip. A multi-layer semiconductor device having laser devices includes lower discrete devices, a lower insulating layer(9), a laser waveguide(17), semiconductor electrodes(15), and a light emitting diode(21'). The lower discrete devices are arranged on a semiconductor substrate(1). The lower insulating layer covers the semiconductor substrate having the lower discrete devices. The laser waveguide is arranged on the lower insulating layer. The semiconductor electrodes are arranged at both sides of the laser waveguide. The light emitting diode is arranged on the laser waveguide and the semiconductor electrodes, and one end thereof is electrically connected to the lower discrete devices.
