Manufacturing method of micro LED display and micro LED display

摘要

PROBLEM TO BE SOLVED: To provide a method for manufacturing a semiconductor chip integrated device capable of manufacturing various semiconductor chip integrated devices such as a micro LED display at low cost, and to provide such a semiconductor chip integrated device. SOLUTION: A droplet-shaped semiconductor chip containing a semiconductor chip 40 and a liquid 50 having a first electrode and a second electrode on an upper surface and a lower surface so that the second electrode side is more strongly attracted to a magnetic field. The ink 200 is supplied to the chip coupling portion on the lower electrode 420 provided on the mounting substrate 400, and the second electrode side of the semiconductor chip 40 in the semiconductor chip ink 200 is attracted by magnetic force to the chip coupling portion by an external magnetic field. After being brought into contact with each other, they are electrically and mechanically bonded to the chip coupling portion by soldering or the like. After that, a plurality of branch line portions extend from the trunk line portion so as to cover the chip coupling portion to form an upper electrode, and the semiconductor chip 40 is connected between the lower electrode 420 and the upper electrode to manufacture a semiconductor chip integration device.
