Integrated circuits with improved gate structures and methods for fabricating integrated circuits with improved gate structures are provided. In an embodiment, a method for fabricating an integrated circuit includes providing a semiconductor substrate with fin structures. A gate-forming material is deposited over the semiconductor substrate and fin structures. The method includes performing a first etch process to etch the gate-forming material to form a gate line having a first side and a second side. The first side and second side of the gate line are bounded with material. The method includes performing a second etch process to etch a portion of the gate line bound by the material to separate the gate line into adjacent gate structures and to define a tip-to-tip distance between the adjacent gate structures.

An apparatus relating generally to a substrate is disclosed. In this apparatus, a first metal layer is on the substrate. The first metal layer has an opening. The opening of the first metal layer has a bottom and one or more sides extending from the bottom. A second metal layer is on the first metal layer. The first metal layer and the second metal layer provide a bowl-shaped structure. An inner surface of the bowl-shaped structure is defined responsive to the opening of the first metal layer and the second metal layer thereon. The opening of the bowl-shaped structure is configured to receive and at least partially retain a bonding material during a reflow process.

Provided is a method of manufacturing a mask blank that is improved in cleaning resistance to ozone cleaning or the like, thus capable of preventing degradation of the mask performance due to the cleaning. The method is for manufacturing a mask blank having, on a substrate, a thin film which is formed at its surface with an antireflection layer made of a material containing a transition metal, and carries out a treatment of causing a highly concentrated ozone gas with a concentration of 50 to 100 vol % to act on the antireflection layer to thereby form a surface modified layer comprising a strong oxide film containing an oxide of the transition metal at a surface of the antireflection layer.

A method for patterning a wafer includes performing a first patterning on a wafer, and after performing the first patterning, calculating a simulated dose mapper (DoMa) map predicting a change in critical dimensions of the wafer due to performing a second patterning on the wafer. The method further includes performing the second patterning on the wafer. Performing the second patterning includes adjusting one or more etching parameters of the second patterning in accordance with differences between the simulated DoMa map and desired critical dimensions of the wafer.

Antireflective residues during pattern transfer and consequential short circuiting are eliminated by employing an underlying sacrificial layer to ensure complete removal of the antireflective layer. Embodiments include forming a hard mask layer over a conductive layer, e.g., a silicon substrate, forming the sacrificial layer over the hard mask layer, forming an optical dispersive layer over the sacrificial layer, forming a silicon anti-reflective coating layer over the optical dispersive layer, forming a photoresist layer over the silicon anti-reflective coating layer, where the photoresist layer defines a pattern, etching to transfer the pattern to the hard mask layer, and stripping at least the optical dispersive layer and the sacrificial layer.
