    Abstract: Methods for forming integrated circuit structures are provided. The method includes providing a substrate including a first diffusion region, a second diffusion region, and an isolation structure separating the first diffusion region and the second diffusion region. The method further includes forming a gate structure over the substrate and forming an inter-layer dielectric (ILD) layer over the substrate. The method further includes forming a cutting mask over a portion of the gate structure over the isolation structure, and the cutting mask has an extending portion covering a portion of the ILD layer. The method further includes forming a photoresist layer having an opening, and a portion of the extending portion of the cutting mask is exposed by the opening. The method further includes etching the ILD layer through the opening to form a trench and filling the trench with a conductive material to form a contact.

    Abstract: Embodiments of mechanisms of a semiconductor device structure are provided. The semiconductor device structure includes a substrate and a metal gate structure formed over the substrate. The semiconductor device structure further includes a funnel shaped hard mask structure formed over the metal gate structure. Formation of voids, which tend to be formed in a rectangular hard mask structure, is prevented. In addition, formation of a self-aligned contact in the semiconductor device becomes easier, and risks of shortage between the contact and a metal gate structure in the semiconductor device decreased. In addition, a method for forming the semiconductor device structure is also provided. The method may include a gate last process.
