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

The fastest way I know to get 'behind the scenes' and learn how analog ASIC design and implementation really works. This was one of the most educational three months I've ever had.
