Provided is a material composition and method for that includes providing a substrate and forming a resist layer over the substrate. In various embodiments, the resist layer includes a multi-metal complex including an extreme ultraviolet (EUV) absorption element and a bridging element. By way of example, the EUV absorption element includes a first metal type and the bridging element includes a second metal type. In some embodiments, an exposure process is performed to the resist layer. After performing the exposure process, the exposed resist layer is developed to form a patterned resist layer.
