Abstract:
A method of forming silicon dioxide films using plasma enhanced chemical vapor deposition (PECVD) uses tetraethyl orthosilicate (TEOS), oxygen or a source of oxygen, and hydrogen as precursors. The method can be carried out at low temperatures in a range of 125 to 175° C. which is useful for manufacturing wafers with through silicon vias.
