Claim:
1. A method for forming a semiconductor structure, comprising: forming a flowable layer over a substrate; driving precursors into the flowable layer before a curing process under a pressure of over 2 atmospheres, wherein the flowable layer has a top portion and a bottom portion and the bottom portion is disposed between the top portion and the substrate such that the precursors enter and react with the top portion and with the bottom portion, wherein the precursors comprise O heating the flowable layer to form a cured layer in the curing process, wherein the curing process is performed under a pressure of over 2 atmospheres, the flowable layer reacts with the precursors in the flowable layer during the curing process, and after the cured layer is formed, no heating process is performed to the cured layer.
