Organic Contamination of Silicon Wafer in Clean Room Air and Its Impact to Gate Oxide Integrity

説明
<jats:title>ABSTRACT</jats:title><jats:p>Organic adsorbates on silicon wafer surfaces exposed to superclean room air were measured to evaluate organic contamination level of silicon wafers stored in a clean bench up to 180min. Such Si wafers were thermally oxidized and the dielectric degradation behavior were systematically investigated. It is found that a carbon contamination level of half a monolayer influences the charge to quasi-breakdown although the degradation mechanism itself remains unchanged.</jats:p>
