Abstract: A method of etching a shallow trench is disclosed in the present invention. By removing the photoresist layer immediately at the end point of the hard mask layer etching and further using the improved process conditions etch the top of the substrate at the same time of the hard mask layer over-etching, such as a lower bias power, a higher pressure and a bigger polymer gases flow rate, the present invention has formed a smooth morphology on the top of the shallow trench.
