Cmos contact etch leakage
WebJan 25, 2024 · Intel, Samsung, TSMC and others are laying the groundwork for the transition from today’s finFET transistors to new gate-all-around field-effect transistors (GAA FETs) at the 3nm and 2nm nodes, starting either next year or in 2024. GAA FETs hold the promise of better performance, lower power, and lower leakage, and they will be required below ... WebIt can be seen that, within an IC structure, metals are used as gate and electrode contacts (Tungsten Silicide, light region above the source and drain), contact plugs (Tungsten Plug) and interconnects (Copper 1 through Copper 5). Diffusion limiting barrier layers (i.e. Ta and TaN) are required to prevent metal diffusion into semiconducting and ...
