About Femtofarads
The femtofarad (fF) equals 10⁻¹⁵ F, the standard unit for transistor gate capacitances in CMOS technology and MEMS sensors. Transistors in 7 nm process nodes have gate capacitances of 0.5-5 fF; MEMS capacitive pressure sensors use sense-gap capacitances of 1-100 fF; integrated-circuit bond-pad parasitics and via coupling are quantified in femtofarads. 1 fF = 10⁻³ pF = 10⁻¹⁵ F.
About Abfarads
The abfarad (abF) is the capacitance unit of the CGS-EMU system, equal to 1 abC / 1 abV = 10 C / 10⁻⁸ V = 10⁹ F, exactly equal to 1 GF in SI. It appeared in nineteenth-century and early twentieth-century electromagnetic engineering texts alongside abohms and abamperes; 1 abF represents the capacitance of a connection storing 10 C at 10 nV. 1 abF = 10⁹ F = 1 GF.
