发明名称 Semiconductor device
摘要 Embodiments relate to a semiconductor device and a method of manufacturing a semiconductor. In embodiments, the method may include a first exposure step of performing an exposure process for forming a first photoresist on a semiconductor substrate at one side of the outside of a trench pattern which will be formed, a first etching step of performing a predetermined dry etching method with respect to the first photoresist, a second exposure step of performing an exposure process for forming a second photoresist at the other side of the outside of the trench pattern, which is a side opposite to the first photoresist, and a second etching step of performing the predetermined dry etching method with respect to the second photoresist.
