Novel RF process monitoring test structure for silicon devices

This paper demonstrates a novel RFCMOS process monitoring test structure. Outstanding agreement in dc and radio frequency (RF) characteristics has been observed between conventional test structure and the new process monitoring test structure for MOSFET with good correlations in measured capacitances also noted for metal-insulator-metal capacitor and MOS varactor. Possible process monitoring test structure is also suggested as a reference benchmarking indicator for interconnects.
