Abstract
An optoelectronic device chip, and a method for making the chip, are disclosed. The chip comprises a device substrate, an optically transparent upper substrate, and a composite spacer layer which includes an adhesive material and a plurality of particles dispersed in said adhesive material. The distance between the device substrate and the upper substrate is controlled by the thickness of the composite spacer layer so that the variation is within the depth of focus of optical system.
