Latest Patents

One of SeungWoo Choi's latest patents is a method for processing a substrate that provides a way to adjust film stress. In this method, a first film is formed on the substrate by supplying a first reactant and a second reactant sequentially and alternately in a first step. The first film is then converted into a second film by supplying a third reactant to the first film in a second step. The film stress of the second film is adjusted by controlling the ratio of the first step and the second step. Another notable patent is a substrate processing method capable of filling a gap structure without forming voids or seams while minimizing damage to the gap structure. This method includes forming a first thin film on a structure by performing a first cycle multiple times, which involves supplying a first reaction gas onto the structure and purging any residue. It also includes forming a second thin film by changing the chemical composition of the first thin film and forming a third thin film that matches the component of the second thin film while filling the gap.
