Essentially all electronic devices that we use today are based on inorganic single-crystalline semiconductors such as Si, GaN, and GaAs, which offer the highest speed, efficiency, sensitivity, and lifetime. However, conventional semiconductor devices are intrinsically/physically bonded to wafers that are thick (0.5-1 mm) and rigid, which limits their application in emerging technologies such as biodegradable/flexible/ three-dimensional electronics. In this talk, I will introduce advanced manufacturing strategies for next-generation electronics based on Layer Transfer technology, which enables the production of freestanding single-crystalline semiconductor device layers by separating them from their epitaxial wafers. This allows distinct opportunities for developing electronic systems that can: (i) completely dissolve in biofluids at physiological pH/temperatures, (ii) conformally adhere on skin to enable convenient, nearly imperceptible human-computer interface, or (iii) achieve ultrahigh device density and versatility through 3D integration of disparate functional layers. More specifically, I will discuss applications such as bioresorbable implantable medical devices, chipless wireless electronic skins, and vertical micro-LEDs for AR/VR display.
