摘要: A dielectric layer is formed by depositing a first dielectric layer above a semiconductor substrate including recessed regions, etching the first dielectric layer to remove any voids and to lower the aspect ratio of the recessed regions, and depositing a second dielectric layer on the first dielectric layer in the recessed regions. The method is particularly useful when the aspect ratios are high for recessed regions formed between patterns.
