In this paper, a novel design of CMOS-MEMS resonator with embedded microheater to control the temperature over the sensing layer was successfully designed and characterized. The CMOS-MEMS resonator was fabricated using 0.35 μm CMOS and post-CMOS micromachining process. Temperature coefficient of resistance (TCR) of aluminum temperature sensor embedded in the membrane was determined by measurement of resistance variation as a function of temperature from 27°C and 150°C. The TCR of the temperature sensor is found to be 0.00386 and 0.00379 for measurements carried out while temperature is increasing and decreasing, respectively. The total resistance of the temperature sensor and the wire interconnects was theoretically determined to be 74.23 Ω and 94.82 Ω, respectively, making a total resistance of 169.05 Ω when measurements are made through the pads. On the other hand the measured resistance at 27°C is found to be 169.06 Ω which is in very good agreement with a difference of 0.006 . The experimental results and analytical values of resistance of the temperature sensor as a function of temperatures shows a good agreement (1.07). TCR of Al is found to 0.00382 with percentage difference of about 2.05 from standard value (39 �10-4 C -1). © 2014 IEEE. date: 2014 publisher: IEEE Computer Society official_url: https://www.scopus.com/inward/record.uri?eid=2-s2.0-84906335946&doi=10.1109%2fICIAS.2014.6869462&partnerID=40&md5=4a80f10089dee877ca72690bc6d5a433 id_number: 10.1109/ICIAS.2014.6869462 full_text_status: none publication: 2014 5th International Conference on Intelligent and Advanced Systems: Technological Convergence for Sustainable Future, ICIAS 2014 - Proceedings place_of_pub: Kuala Lumpur refereed: TRUE isbn: 9781479946549 citation: Ahmed, A.Y. and Dennis, J.O. and Md Khir, M.H. and Mohamad Saad, M.N.
