Abstract

Low resistance Ohmic contacts were produced by evaporating nickel and aluminum films on barium titanate substrates, and subsequently irradiating them with Q-switched ruby laser pulses (λ = 0.694 μm, τ = 15×10−9 s, pulse energy density 1.0 − 1.2 J cm−2). Stability and aging behavior of these contacts were comparable to those of conventional contacts, i.e. flame sprayed aluminum, In-Sn solder, fritted silver and electroless nickel under test conditions (ambient temperatures in air, in boiling water and organic liquids at 150°C, 100 psi).
