Abstract:
A method of forming an interlayer dielectric for a semiconductor device minimizing voids. During a process for forming a PMD oxide film being used as an interlayer dielectric, since TEOS impurities are added under a low-pressure controlled atmosphere, and gap filling characteristics are improved. Therefore, voids are minimized in the PMD oxide film. As a result, contact holes are prevented from shorting with each other through a void, and thus current leakage is suppressed. Further, it is not necessary to perform a rapid thermal anneal to improve the density of the PMD oxide film, nor to deposit a second PMD oxide film after planarization. As a result, the manufacturing process can be simplified.
