    Abstract: A method of manufacturing an integrated circuit device and an integrated circuit device prepared according to the method, the method including forming a silicon oxycarbonitride (SiOCN) material layer on an active region of a substrate, the forming the SiOCN material layer including using a precursor that has a bond between a silicon (Si) atom and a carbon (C) atom; etching a portion of the active region to form a recess in the active region; baking a surface of the recess at about 700° C. to about 800° C. under a hydrogen (H2) atmosphere, and exposing the SiOCN material layer to the atmosphere of the baking while performing the baking; and growing a semiconductor layer from the surface of the recess baked under the hydrogen atmosphere.

    Abstract: An integrated circuit device includes a fin type active area protruding from a substrate and having an upper surface at a first level; a nanosheet extending in parallel to the upper surface of the fin type active area and comprising a channel area, the nanosheet being located at a second level spaced apart from the upper surface of the fin type active area; a gate disposed on the fin type active area and surrounding at least a part of the nanosheet, the gate extending in a direction crossing the fin type active area; a gate dielectric layer disposed between the nanosheet and the gate; a source and drain region formed on the fin type active area and connected to one end of the nanosheet; a first insulating spacer on the nanosheet, the first insulating spacer covering sidewalls of the gate; and a second insulating spacer disposed between the gate and the source and drain region in a space between the upper surface of the fin type active area and the nanosheet, the second insulating spacer having a multilayer structure.
