Well, this is the paper we really
wanted to seal the deal to brand our product as "Transformational Silicon
Electronics" and guess what? That happened in ACS Nano by none other than
Jhonathan et al.! There are some more coming from him before he leaves
us but he will always be remembered for his calm demure, his integration
ability (which is better than mine) and his dedication for the group. So, all hail
to Jhonathan!

In today’s traditional
electronics like in computers or in mobile phones, billions of high
performance, ultra-low power devices are neatly integrated in extremely compact
areas on rigid and brittle but low-cost bulk mono-crystalline silicon (100)
wafers. Ninety percent of global electronics are made up of silicon. Therefore,
we have developed a generic low-cost regenerative batch fabrication process to
transform such wafers full of devices into thin (5 um), mechanically flexible, optically
semi-transparent silicon fabric with devices; then recycling the remaining
wafer to generate multiple silicon fabric with chips and devices ensuring
low-cost and optimal utilization of the whole substrate. We show mono,
amorphous and poly-crystalline silicon and silicon dioxide fabric – all from
low-cost bulk silicon (100) wafers with semiconductor industry’s most advanced
high-k/metal gate stack based high performance,
ultra-low power capacitors, field effect transistors, energy harvesters and
storage to emphasize the effectiveness and versatility of this process to
transform the traditional electronics into flexible and semi-transparent one
for multi-purpose applications.
