This package is very small and cheap to produce. It also has benefits due to the lack of bond wires. Bond wires increase parasitic inductance, and can be a problem for high speed designs.

The downside is that they are very tiny!

The last 5 layers of the Skywater PDK define the layers necessary to build the WLCSP package.

Course feedback

Don't think twice about taking this course, It uses a unique method, you get to do stuff yourself and learn by playing around. Getting through this course and designing my own ASICs was the greatest experience of my life.
