Abstract

A method of fabricating a semiconductor device using a trench isolation method including a hydrogen annealing step, wherein a photoresist pattern is formed on a semiconductor substrate, a pad insulating layer may be formed before forming the photoresist pattern, the semiconductor substrate is etched using the photoresist pattern as an etching mask to form a trench, and an isolation layer is formed in the trench. To remove damages created in an active region defined by the isolation layer, the semiconductor substrate having the isolation layer is annealed in a hydrogen atmosphere.
