High-Density Soft-Matter Electronics

The disclosure describes a soft-matter electronic device having micron-scale features, and methods to fabricate the electronic device. In some embodiments, the device comprises an elastomer mold having microchannels, which are filled with an eutectic alloy to create an electrically conductive element. The microchannels are sealed with a polymer to prevent the alloy from escaping the microchannels. In some embodiments, the alloy is drawn into the microchannels using a micro-transfer printing technique. Additionally, the molds can be created using soft-lithography or other fabrication techniques. The method described herein allows creation of micron-scale circuit features with a line width and spacing that is an order-of-magnitude smaller than those previously demonstrated.

PROCESS FOR MANUFACTURING AN OPTICAL MICROELECTROMECHANICAL DEVICE HAVING A TILTABLE STRUCTURE WITH AN ANTIREFLECTIVE SURFACE

For manufacturing an optical microelectromechanical device, a first wafer of semiconductor material having a first surface and a second surface is machined to form a suspended mirror structure, a fixed structure surrounding the suspended mirror structure, elastic supporting elements which extend between the fixed structure and the suspended mirror structure, and an actuation structure coupled to the suspended mirror structure. A second wafer is machined separately to form a chamber delimited by a bottom wall having a through opening. The second wafer is bonded to the first surface of the first wafer in such a way that the chamber overlies the actuation structure and the through opening is aligned to the suspended mirror structure. Furthermore, a third wafer is bonded to the second surface of the first wafer to form a composite wafer device. The composite wafer device is then diced to form an optical microelectromechanical device.
