Latest Patents
Among Aya's latest patents is the invention related to the "LED array alignment mark, method and mask for forming same." This advanced technology allows for the creation of alignment marks on light-emitting diode (LED) array chips, which are formed simultaneously with the chip's light-emitting areas. The innovative process utilizes a combined mask consisting of two parts. In the first part, impurities are introduced through specific windows to define the light-emitting areas. Subsequently, these windows are covered with an etching resist, and the substrate is etched to create a topographical relief feature defined by the second part of the mask. This relief feature serves as an alignment mark. When these LED chips are mounted onto supporting surfaces, they can be precisely aligned by recognizing patterns of light reflected from the relief, allowing for accurate placement and improved functionality.
