Abstract :
The letter explains first how a capacitor made with anodic oxidations of aluminium can improve the bandwidth of GaAs integrated circuits. The technology of this capacitor is described with emphasis on the crossing of the edge of the capacitor by the upper metallisation. Capacitances of about 1500 pF/mm2 have been obtained with a breakdown voltage in the 5¿10 V region.
