Description

This talk will discuss heterogeneous integration technologies to enable the integration of functional nanomaterials and devices across length scales and material boundaries. The following topics will be presented: (1) Gas Phase Electrodeposition of Nanomaterials -- Gas phase electrodeposition is a nanomaterial deposition and growth process. It replaces the liquid medium and ions in the wet chemical analog with a carrier gas, high mobility gas ions, and charged nanoparticles. The discovered gas phase counterpart enables the site selective deposition of nanomaterials on pre-patterned surfaces. The process is applied to fabricate nanostructured electrodes, multimaterial / multifunctional sensor arrays, nanoscopic bondwires, SERS enhancement layers, and reactive nanoparticle films. It is also used to realize a “Nanolens Based Analyte Recording Chip”. (2) Fluidic Self-assembly of Microscopic Semiconductor Chips -- The goal of the second process is to enable the assembly and electrical connection of microscopic semiconductor chips on foreign substrates in a massively parallel fashion. The chips are smaller than what can be assembled effectively using robotic pick and place. The physics and applications of fluidic self-assembly will be described. The process has been applied to fabricate solid-state lighting modules in a reel-to-reel fashion. (3) Metamorphic and stretchable Electronics -- Heterogeneous integration of semiconductor chips on foreign substrates enables the distribution of electronic functions on elastomeric supports, which in turn enables the realization of stretchable and metamorphic electronics. First demonstrators include metamorphic LED and microphone arrays. The arrays morph from a planar to a spherical to a cone and box like topologies with corresponding emission and receive characteristics, respectively.
