    Abstract: A method of designing a layout of a semiconductor device includes preparing a layout for a semiconductor integrated circuit, the preparing of the layout including providing lower and upper metal patterns and via patterns, which are vertically interposed between the lower and upper metal patterns, performing a retargeting process on the lower and upper metal patterns, classifying the via patterns to extract at least one risk via from the via patterns and changing a position of the risk via. During the changing of the position of the risk via, all of the via patterns, other than the risk via, are unchanged in position thereof. Related systems and computer program products are disclosed.

    Abstract: A method for forming an ultra fine contact hole includes: forming a KrF photoresist pattern on a semiconductor substrate providing an insulation layer, the KrF photoresist pattern exposing a predetermined region for forming a contact hole on the insulation layer; forming a chemically swelling process (CSP) chemical material-containing layer being reactive to the KrF photoresist pattern on an entire surface of the semiconductor substrate; forming a chemical material-containing pattern encompassing the KrF photoresist pattern by reacting the chemical material-containing layer with the KrF photoresist pattern through a chemically swelling process to decrease a critical dimension of the contact hole; rinsing the semiconductor substrate; and increasing a thickness of a sidewall of the chemical material-containing pattern to a predetermined thickness by performing a resist flow process (RFP) that makes the chemical material-containing pattern flowed to decrease the critical dimension (CD) of the contact hole.
