Werkwijze voor het vervaardigen van een LED matrixkop.

摘要

There is disclosed a method of making an LED array head capable of simplifying an electrical wiring arrangement process between an individual electrode of each LED component and an external wiring upon formation of the LED array on a ceramic substrate. The inventive method includes the steps of: forming an external wiring on a portion of top surface of a substrate having a recess and an internal wiring on an entire top surface of said recess; bonding a respective LED component into said recess; forming an insulating film on the entire top surface of the substrate and the LED component; forming contact windows by selectively etching said insulating film so as to make access to the external wiring and an individual electrode disposed on the top surface of said LED component; and forming secondary wiring for electrically coupling the individual electrode with the external electrode through said contact windows.
