## Abstract A differential AC‐chip calorimeter capable of measuring the step in heat capacity at the glass transition in nanometer‐thin films is described. Because of the differential setup, pJ/K sensitivity is achieved. Heat capacity can be measured for sample masses below 1 ng in broad temperatur
