  • Publication number: 20240120208
    Abstract: A method for fabricating a spacer includes steps as follows: Firstly, an etch stop structure is provided. The etch stop structure includes a silicon nitride-containing capping layer covering a substrate. Next, an etching process is performed to remove a portion of the silicon nitride-containing capping layer. A wet process is then performed making a sulfide-containing treatment agent to contact the remaining portion of the silicon nitride-containing capping layer.
