Conference Proceeding: Perfect hillockless metallization (PHM) process for VLSI
[show abstract] [hide abstract]
ABSTRACT: Enhanced growth of chemically converted aluminum oxide is observed by an introduction of sputter etching as surface treatment of aluminum prior to the conversion. The aluminum oxide film suppresses the formation of aluminum hillocks, aluminum voids and cracks in the passivation film which reduce both the yield and reliability of VLSI.Electron Devices Meeting, 1986 International; 02/1986
