Photovoltaics

In collaboration with Dr. Minseo Park (Department of Physics, Auburn University), we are investigating multiple fabrication methods and configurations of advanced / flexible photovoltaics. We are developing and characterizing our unique structures (including alternative configurations, hybrid organic/inorganic, and sensitized with various nanostructures), with the hopes of enhanced performance (i.e., efficiency) and ease of fabrication (i.e., roll-to-roll).

TSV

With the help of Charles Ellis in the AMNSTC, we have developed a reliable through-Si via (TSV) process that we are using in our in-house 2.5D / 3D packaging and integration. This technology uses PEALD deposited Ru seed layers and electroplated Cu TSVs.

These structures exhibit excellent filling, high aspect ratio and excellent uniformity. Current efforts are in characterizing the RF / signal integrity performance of these structures, as well as exploring integration density, reliability, forming superconducting versions, etc.
