Abstract

Low- and high-barrier Schottky diodes have been combined with bipolar transistors to produce planar integrated-circuit low-area memory cells that hold at 75 /spl mu/W. Low-barrier diodes formed on p-type ion-implanted silicon (10/SUP 17/ cm/SUP -3/) are used as high-resistance collector loads. High-barrier diodes formed on n-type epitaxial silicon (10/SUP 16/ cm/SUP -3/) provide low-capacitance low-leakage coupling to digit lines in a memory array. The highly reproducible rhodium silicide on silicon Schottky diodes, as well as high-quality ohmic contacts, are formed in one sequence of sputtering and high-temperature operations. The process is fully compatible with beam-lead technology. It is estimated that a 512-word memory module using these cells would operate at a 60-ns READ or WRITE cycle time.
