Described herein is a method and system for dual stretching of wafers to create isolated segmented chip scale packages. A wafer having an array of light-emitting diodes (LEDs) is scribed into LED segments, where each LED segment includes a predetermined number of LEDs. The scribed wafer is placed on a stretchable substrate or tape. The tape is stretched and a layer of optically material is placed in the separation gaps. The stretched wafer is scribed on a LED level. The tape is stretched and another layer of optically opaque material is placed in the separation gaps. The same or different optically opaque material can be used for the layers. The two layers of optically opaque material are formed to provide electrical connectivity between the LEDs in each LED segment. In an implementation, each segment or LED is individually addressable.
