System and method of fabrication and application of thin-films with continuously graded or discrete physical property parameters to functionally broadband monolithic microelectronic optoelectronic/sensor/actuator device arrays
System and method of fabrication and application of thin-films with continuously graded or discrete physical property parameters to functionally broadband monolithic microelectronic optoelectronic/sensor/actuator device arrays
A system and method are provided to fabricate thin-films having different physical property parameters or having physical property parameters that continuously change across functionally broadband monolithic device arrays. The fabrication method deposits the thin-film including layers on a substrate of a monolithic chip. The method defines a desired gradient profile of each layer forming the thin-film, each gradient profile including a desired thinnest profile and a desired thickest profile. The method further aligns an aperture of a mask over the substrate to form the thin-film and calculates a shutter speed for the specified gradient profile of each layer across the desired area of the substrate, and deposits each layer on the substrate, through the aperture, as the aperture of the shutter moves at the calculated shutter speed from the desired thinnest profile of each layer to the desired thickest profile of each layer.
