Abstract: A sealing layer is formed around a contact structure of a resistor in a semiconductor device. The sealing layer fills in and occupies areas around the contact structure in which an overhang of a hard mask layer occurs as a result of lateral etching of the contact structure during formation of the contact structure. The sealing layer may include a material that can be selectively deposited on sidewalls of the contact structure and not on other layers and/or structures in the semiconductor device. The sealing layer may reduce the likelihood of void formation, in a dielectric layer, that might otherwise occur due to the overhang of the hard mask layer. The reduced likelihood of void formation may enable the dielectric layer to fully fill in the areas around the resistor in the semiconductor device, thereby increasing the structural integrity of the semiconductor device.
