    摘要: A method of forming an overlay mark includes disposing a first feature of a plurality of first alignment segments extending along a first direction in a first layer, disposing a second feature of a plurality of second alignment segments extending along a second direction in a second layer over the first layer, and forming a third feature of a plurality of third alignment segments extending along the first direction and a plurality of fourth alignment segments extending along the second direction in a third layer over the second layer. In a plan view, each first alignment segment of the first alignment segments is adjacent to a corresponding third alignment segment of the third alignment segments along the first direction, and each second alignment segment of the second alignment segments is adjacent to a corresponding fourth alignment segment of the fourth alignment segments along the second direction.

    摘要: Provided is a photoresist that includes a polymer having a backbone that is breakable and a photo acid generator that is free of bonding from the polymer. Further, provided is a method of fabricating a semiconductor device. The method includes providing a device substrate. A material layer is formed over the substrate. A photoresist material is formed over the material layer. The photoresist material has a polymer that includes a backbone. The photoresist material is patterned to form a patterned photoresist layer. A fabrication process is then performed to the material layer, wherein the patterned photoresist layer serves as a mask in the fabrication process. Thereafter, the patterned photoresist layer is treated in a manner that breaks the backbone of the polymer. The patterned photoresist layer is then removed.

    摘要: The present disclosure provides a method for forming patterns in a semiconductor device. In accordance with some embodiments, the method includes providing a substrate, a patterning-target layer over the substrate, and a hard mask layer over the patterning-target layer; forming a first pattern in the hard mask layer; removing a trim portion from the first pattern in the hard mask layer to form a trimmed first pattern; forming a first resist layer over the hard mask layer; forming a main pattern in the first resist layer; and etching the patterning-target layer using the main pattern and the trimmed first pattern as etching mask elements to form a final pattern in the patterning-target layer. In some embodiments, the final pattern includes the main pattern subtracting a first overlapping portion between the main pattern and the trimmed first pattern.

    摘要: The present disclosure describes methods for transferring a desired layout into a target layer on a semiconductor substrate. An embodiment of the methods includes forming a first desired layout feature as a first line over the target layer; forming a spacer around the first line; depositing a spacer-surrounding material layer; removing the spacer to form a fosse pattern trench surrounding the first line; and transferring the fosse pattern trench into the target layer to form a fosse feature trench in the target layer, wherein the fosse feature trench surrounds a first portion of the target layer that is underneath a protection layer. In some embodiments, the method further includes patterning a second desired layout feature of the desired layout into the target layer wherein the fosse feature trench and the protection layer serve to self-align the second desired layout feature with the first portion of the target layer.
