    摘要: A flip-chip attach method includes the steps of: attaching a chip on a transparent substrate such that each connecting pad of the chip is aligned with each electrical connection pad on the transparent substrate; and irradiating each connecting pad and each electrical connection pad from a side of the transparent substrate with a laser beam so as to weld the connecting pad to the electrical connection pad. Furthermore, the invention also provides a flip-chip attach structure including a transparent substrate and at least one chip. A surface of the transparent substrate is formed with a plurality of electrical connection pads, and the chip has a plurality of connecting pads. The connecting pads and the electrical connection pads are irradiated with a laser beam and are welded to each other. Thus, the chip is mounted to the transparent substrate.
