METHOD FOR PLANARIZING THIN LAYER OF SEMICONDUCTOR DEVICE |
摘要 |
A method for planarizing a layer of a semiconductor device includes depositing a high density plasma (HDP) oxide layer over a wafer to have a reflective index distribution that is inversely proportional to a thickness distribution of the HDP oxide layer. A chemical mechanical polishing process is performed on the HDP oxide layer.
