These surface hydroxyl groups were the primary sites for moisture adsorption ,
which would increase the dielectric permittivity and cause metal interconnect
integration problems . The surface silanol groups also formed Si - O - Si bonds ...

SURFACE TREATMENT Untreated silica xerogel films contained a large amount
of Si - OH at pore surfaces and readily adsorbed water . Due to their high porosity
and large surface areas , the moisture content in xerogel films could be ...

for the S3 film and is related to the time needed to grow a steady - state Si0 , - rich
surface layer , as will be discussed in subsequent sections . The etch rate
decreases with increasing Si content , with steady - state etch rates of 15 . 2 + 1 .
