.... A technique called “passive voltage contrast” may reveal shorts or floating conductors in integrated circuits. Passive voltage contrast does not require any special equipment, it simply consists of taking an ordinary SEM image and adjusting the beam current, sample tilt, raster size, or raster rate so...
