16. Optimization of High-k films on Si Substrate : fabrication and characterization
University essay from Lunds universitet/Fysiska institutionen; Lunds universitet/Fasta tillståndets fysikAbstract : In the present diploma project work, metal oxide semiconductor capacitors were fabricated on Silicon substrate. The oxide layer was formed by atomic layer deposition of high permittivity materials, HfO2 and Al2O3. The high-k films were grown using 65 ALD cycles at various deposition temperatures. READ MORE
