I will give a slice of cake that is 32 nanometers thick to whoever can identify what size of the semiconductor device fabrication was used in the sheet of microchips that are in my April 7th (2011) background or profile photo. The rest of the cake will be given to whoever can identify what kind of microchips does one of the wafers contain. Double the about if a person can answer both questions corretly before April 18th.
