The method includes providing a substrate and forming a material layer over the substrate. The method includes forming a second material layer over the first material layer. The method includes performing a first patterning process to the second material layer to form a trench in the second material layer. The first patterning process defines a width size of the trench, the width size being measured in a first direction. The method includes performing a second patterning process to the trench to transform the trench. The second patterning process defines a length size of the transformed trench. The length size is measured in a second direction different from the first direction. The method also includes filling the transformed trench with a conductive material."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Metal layer end-cut flow","description":"A method of patterning a metal layer is disclosed.
