Abstract :
The electrical properties of plasma-enhanced undoped silicon dioxide and subatmospheric pressure chemical vapor deposited borophosphosilicate glass films used in sub-half-micron ULSI were investigated and compared for 200 mm p-type silicon wafers. The capacitance-voltage (C-V), surface photo voltage (SPV), and current-voltage (I-V) measurement methods were applied for characterization of the film properties. The revealed variation of the charge and current values across the wafer for as-deposited and densified films and its causes are discussed
