High speed systems demand faster logic than current silicon bipolar technology can offer. Hybrid or monolithic circuits using gallium arsenide FETs provide an answer. The FETs require careful handling if electrical or mechanical damage is to be avoided. The problems of bonding a large number of these devices to a thin-film circuit to produce a working hybrid logic element are discussed. Techniques for their solution are given with reference to a completed experimental hybrid circuit.
