Modern Semiconductor Devices For Integrated Circuits ((hot))

Used in high-performance caches (e.g., IBM’s Power processors). eDRAM uses a trench capacitor stacked below the logic transistors, offering 3-4x density over SRAM but requiring refresh cycles.

Samsung was first to mass-produce GAA (MBCFET™) at 3nm (2022), followed by TSMC’s N2 (2nm) slated for 2025-2026. Intel’s 20A and 18A nodes also adopt GAA (RibbonFET). This device architecture is expected to carry the industry through the 1.5nm node and beyond. modern semiconductor devices for integrated circuits

To extend scaling below 3nm, the industry has transitioned to , specifically the nanosheet (or nanoribbon) architecture. Unlike FinFETs, GAA devices feature multiple horizontal nanosheets (typically 2-4) stacked vertically, with the gate completely surrounding each sheet. Used in high-performance caches (e

Here is an exploration of the cutting-edge devices currently defining the semiconductor landscape. 1. The Transition from Planar to 3D: FinFETs Intel’s 20A and 18A nodes also adopt GAA (RibbonFET)
