Abstract:
A method is provided for fabricating a thin-film electronic device employing a piezoelectric plate. The method provides a plurality of piezoelectric plates, and a substrate with electronic devices, each electronic device including a top surface well. A piezoelectric plate suspension is formed and flowed over the substrate. In response to the piezoelectric plate suspension flow, piezoelectric plates are captured in the top surface wells. The electric device top surface wells have well bottom surfaces, with bottom electrical contacts formed on the bottom surfaces. Thus, the capture of a piezoelectric plate in a top surface well entails interfacing a piezoelectric plate electrode, either the first electrode or the second electrode, to the bottom electrical contact. Subsequent to capturing the piezoelectric plates in the top surface wells, a thin-film process forms a conductive line overlying the exposed piezoelectric device electrode (i.e., the electrode not connected to the bottom electrical contact).
