    摘要: A method of manufacturing a semiconductor device includes an improved technique of filling a trench to provide the resulting semiconductor device with better characteristics and higher reliability. The method includes forming a trench in a semiconductor layer, forming a first layer on the semiconductor layer using a silicon source and a nitrogen source to fill the trench, curing the first layer using an oxygen source, and annealing the second layer. The method may also be used to form other types of insulating layers such as an interlayer insulating layer.
