If you think
you've had trouble in the past trying to find small components that
you drop in the lab, you haven't seen anything yet - literally. The
new Gallium Nitride (GaN) ICs that feature both high frequency and high
power density are as clear as glass. Their high energy band gaps allow
visible light photons to pass right through without absorption, which
we perceive as color. The only visible feature on the chips will be
the metallized bonding pads. It will be interesting to "see" what kind
of chip graffiti shows up on these devices!
