The processing run for the frequency divider circuits completed in the previous quarter produced individual working p-MODFET devices. However several processing issues affecting device yield precluded the demonstration of a functioning frequency divider circuit. It is estimated that a device yield in excess of 95 % is required to get 10 % of the frequency divider circuits to work. Some of the key yield limiting steps in the process have been identified and are described below.
