As long as I know the thermal oxide resistivity is not affected by silicon doping. Also doping doesn't cause any electrical leakage. Electrical leakage is caused more by metallic contamination, defects, etc. SM ----- Original Message ----- From: "ameya g"To: Sent: Saturday, December 20, 2008 4:00 AM Subject: [mems-talk] Oxidation of doped silicon > Hi all > > I was curious to know whether the thermal oxide (~100 nm) grown from doped > silicon has lower resistivity than the one grown from undoped silicon? > > Can such an oxide cause any electrical leakage?
