Abstract:
A process for forming a film of material comprising devices, said process comprising steps of:introducing particles in a selected manner through a surface of a substrate to a selected depth underneath said surface, said particles being at a concentration at said selected depth to define a substrate material to be removed above said selected depth; and providing energy to a selected region of said substrate to initiate a controlled cleaving action at said selected depth in said substrate, whereupon said controlled cleaving action is made using a propagating cleave front to free a portion of said material to be removed from said substrate; wherein said substrate material to be removed comprise a device or device portion therein, the device or device portion being selected from the group consisting of at least a photonic device, a piezoelectric device, a microelectromechanical device, a sensor, an actuator, a solar cell, a biological device, and a biomedical device.
