Abstract
Examples of the present application provide a semiconductor device, a memory system and a fabrication method of a semiconductor device. The semiconductor device includes: a silicon contact structure; a metal silicide layer on one side of the silicon contact structure; a bit line structure located on the side of the metal silicide layer away from the silicon contact structure and extending in a first direction; and a sidewall structure covering the opposite sides of the bit line structure and the opposite sides of the metal silicide layer in the first direction and extending further to cover the opposite sides, in the first direction, of the first end of the silicon contact structure proximate to the metal silicide layer.
