WebHigh-k and Metal Gate Transistor Research. Intel made a significant breakthrough in the 45nm process by using a "high-k" (Hi-k) material called hafnium to replace the … As the thickness scales below 2 nm, leakage currents due to tunnelingincrease drastically, leading to high power consumption and reduced device reliability. Replacing the silicon dioxide gate dielectric with a high-κ material allows increased gate capacitance without the associated leakage effects. First … Ver mais The term high-κ dielectric refers to a material with a high dielectric constant (κ, kappa), as compared to silicon dioxide. High-κ dielectrics are used in semiconductor manufacturing processes where they are … Ver mais Silicon dioxide (SiO2) has been used as a gate oxide material for decades. As metal–oxide–semiconductor field-effect transistors (MOSFETs) have decreased in size, the thickness of the silicon dioxide gate dielectric has steadily decreased to increase the Ver mais Industry has employed oxynitride gate dielectrics since the 1990s, wherein a conventionally formed silicon oxide dielectric is infused with a small amount of nitrogen. The nitride content subtly raises the dielectric constant and is thought to offer other … Ver mais Replacing the silicon dioxide gate dielectric with another material adds complexity to the manufacturing process. Silicon dioxide can be formed by oxidizing the underlying silicon, ensuring a uniform, conformal oxide and high interface quality. As a consequence, … Ver mais • Electronics portal • Low-κ dielectric • Silicon–germanium • Silicon on insulator Ver mais • Review article by Wilk et al. in the Journal of Applied Physics • Houssa, M.
