Abstract

CrCxNy and CrSixCy thin films were deposited under low pressure by metallorganic chemical vapor deposition (MOCVD) in the temperature ranges 380-450°C and 450-500°C, respectively, using Cr(NEt2)4 and CrCH2SiMe34 as single-source precursors.The growth was achieved in a cold-wall vertical reactor using, respectively, H2 and He as the carrier gases. Both types of films exhibit a mirrorlike surface morphology and are amorphous asdeposited. The CrCxNy layers start to crystallize at 600°C after annealing for 1 h under vacuum,whereas it is necessary to reach 650°C under H2 atmosphere. In both cases, the original ternary phase Cr3(C0.8N0.2)2 crystallizes. The resistivity of as-deposited amorphous CrCxNy films is typically 600. cm, and it decreases to 150 #. cm after annealing upon the formation of polycrystalline Cr3#C,N#2 films. The CrSixCy layers have a very stable amorphous structure until 850°C for 4 h. In spite of their metallic appearance, they exhibit a high resistivity compared to the Cr3#C,N#2 films. The main characteristics of these Cr-based layers is presented and discussed.
