In this work, we concern ourselves with the fabrication of thin-film transducers. A method of creating thin-film LiNbO metal transducer devices easily and cheaply would lead to more accessible technology for a wide variety of communications and MEMs applications.
Scalable and cheap fabrication of thin films (less than 50 μm thick) has the potential to revolutionize aerospace, bioengineering, and consumer electronics with small and flexible electronic devices. Controlled spalling, a method capable of producing these benefits and more, controls the stresses within a substrate and allows for large-scale release of the desired layer. In this work, controlled spalling is implemented in a laboratory setting using electroplating to produce these stresses, then analyzed and refined while applying it to the case of thin-film lithium niobite transducers.
