About Amperes per square inch
The ampere per square inch (A/in²) equals 1 / (0.0254)² A/m² ≈ 1550 A/m², used in US power semiconductor datasheets and electroforming specifications. JEDEC JESD22 and IPC standards specify maximum allowable current density in bond wires and copper interconnects in A/in²; electroforming of micro-components targets 0.5-5 A/in². 1 A/in² ≈ 1550 A/m² = 0.155 A/cm².
About Femtoamperes per square metre
The femtoampere per square metre (fA/m²) equals 10⁻¹⁵ A/m². Leakage current density through the dielectric of a high-quality capacitor at rated voltage is in the fA/m² range; dark current density in cooled CCD image sensors at -30 °C is around 1-10 fA/m²; radiation-induced leakage in neutron-irradiated MOS gate oxides is measured in fA/m². 1 fA/m² = 10⁻¹⁵ A/m² = 10⁻³ pA/m².
