Abstract

In this study, low-temperature deuterium annealing (LTDA) at 300 °C is proposed to enhance both the performance and reliability of silicon-based high-k metal gate (HKMG) MOSFETs. A comparative study with hydrogen (H2) annealing under identical conditions is conducted to evaluate the specific impact of deuterium (D2). Comprehensive DC characterizations and evaluations of stress immunity under hot-carrier injection (HCI) and positive bias stress (PBS) conditions, are performed. The results confirm that even at a low temperature of 300 °C, D2 has a more substantial effect on device performance and reliability compared to H2. This study provides a guideline for reducing the annealing temperature in the fabrication of HKMG MOSFETs.

期刊介绍： The IEEE Journal of the Electron Devices Society (J-EDS) is an open-access, fully electronic scientific journal publishing papers ranging from fundamental to applied research that are scientifically rigorous and relevant to electron devices. The J-EDS publishes original and significant contributions relating to the theory, modelling, design, performance, and reliability of electron and ion integrated circuit devices and interconnects, involving insulators, metals, organic materials, micro-plasmas, semiconductors, quantum-effect structures, vacuum devices, and emerging materials with applications in bioelectronics, biomedical electronics, computation, communications, displays, microelectromechanics, imaging, micro-actuators, nanodevices, optoelectronics, photovoltaics, power IC''s, and micro-sensors. Tutorial and review papers on these subjects are, also, published. And, occasionally special issues with a collection of papers on particular areas in more depth and breadth are, also, published. J-EDS publishes all papers that are judged to be technically valid and original.
