Standard Oil’s BN—975 planar diffusion sources were used to fabricate integrated resistors. Dopant transfer was done in a N2:02:H2 ambient at 975 C. Two methods of removing the crystal defect layer formed at the surface, low temperature oxidation (LTO) and a nitric acid soak, were evaluated. Successful layer removal was achieved with the LTO. The nitric acid soak met with limited success.
