The effects of plasma treatment on the texture and grain size distribution of aluminum thin films on polyimide substrates have been investigated. Oxygen-argon plasma treatment increased the average grain size and enhanced the (111) film texture. Short oxygen-argon plasma treatment resulted in Al films with bimodal grain structure and even in-plane texture of {111}<11<(2)over bar>> type. The preferential nucleation and grain growth of (111) grains are discussed in terms of interface energy anisotropy.
The effects of plasma treatment of polyimide substrates on the texture and grain size distribution of aluminum thin films were studied. Oxygen-argon plasma treatment increased the average grain size and enhanced the (111) film texture. For short oxygen-argon plasma treatment times, the deposited Al films showed a (111) texture with a bimodal grain structure and even a {111}<11<(2)over bar>> type in-plane texture. The preferential nucleation and grain growth of (111) grains are discussed in terms of the interface energy anisotropy.
