Abstract: IEEE Electron Devices Society is celebrating 100 years of the Field Effect Transistor (FET) in 2025. The first Canadian patent filed by Julius Lilienfeld on 22 October 1925. During the past century there was a phenomenal developments and innovations of the FET that contributed to many applications including computing and communications. The contribution of dielectrics to FET’s development is highly significant. Historically SiO2 was the main driver of MOSFETs as the transistor’s gate dielectric. Once the thickness of SiO2 reached the onset of direct tunneling region (<1.5 nm) HfO2-based high-k insulators were introduced to suppress the direct-tunneling leakage current. The transistor has transformed from a planar device to a three-dimensional device to a gate all around device. Several applications of high-k dielectrics have emerged incuding ferroelectric FETs and resistive random-access memory (RRAM) devices that are being investigated for possible implementation in systems with artificial intelligence hardware. The electrical performance in these devices depends on the dielectric deposition process, precise selection of deposition parameters, pre-deposition surface treatments and subsequent thermal budget. The talk will outline the role of dielectrics from FETs to modern nanoelectronics devices and systems.
