Abstract :
A novel liquid crystal for CMOS device diagnostics is discussed. The liquid crystal composition yields a threshold voltage of 1-2 Vrms and permits field-effect viewing of 5 volt logic families. Dark field illumination of cholesteric liquid crystals to provide wider temperature ranges for mapping hot spots is also discussed.
