The Pd‐In‐Ge nonspiking Ohmic contact ton‐GaAs has been investigated using the transmission line, the Kelvin, and the Cox and Strack structures. It has been found that a layered structure of Pd/In/Pd/n‐GaAs with 10–20 A˚ of Ge imbedded in the Pd layer adjacent to the GaAs can lead to a hybrid contact. When the Ohmic formation temperature is above 550 °C, a layer of InxGa1−xAs doped with Ge is formed between the GaAs structure and the metallization. When the Ohmic formation temperature is below 550 °C, a regrown layer of GaAs also doped with Ge is formed at the metallization/GaAs interface. The contact resistivity of 2–3×10−7&OHgr; cm2for this contact structure is nearly independent of the contact area from 900 to 0.2 &mgr;m2. Low‐temperature Ohmic characteristics and thermal stability are also examined.
