    Abstract: The present disclosure provides lithography resist materials and corresponding lithography techniques for improving lithography resolution, in particular, by reducing swelling of resist layers during development. An exemplary lithography method includes performing a treatment process on a resist layer to cause cross-linking of acid labile group components of the resist layer via cross-linkable functional components, performing an exposure process on the resist layer, and performing a development process on the resist layer. In some implementations, the resist layer includes an exposed portion and an unexposed portion after the exposure process, and the treatment process reduces solubility of the unexposed portion to a developer used during the development process by increasing a molecular weight of a polymer in the unexposed portion. The treatment process is performed before or after the exposure process. The treatment process can include performing a thermal treatment and/or an electromagnetic wave treatment to heat the resist layer.

    Abstract: Under layer composition and methods of manufacturing semiconductor devices are disclosed. The method of manufacturing semiconductor device includes the following steps. A layer of an under layer composition is formed, wherein the under layer composition includes a polymeric material and a cross-linker, and the cross-linker includes at least one decomposable functional group. A curing process is performed on the layer of the under layer composition to form an under layer, wherein the cross-linker is crosslinked with the polymeric material to form a crosslinked polymeric material having the at least one decomposable functional group. A patterned photoresist layer is formed over the under layer. An etching process is performed to transfer a pattern of the patterned photoresist layer to the under layer. The under layer is removed by decomposing the decomposable functional group.

    Abstract: The present disclosure relates to a lithographic tool arrangement for semiconductor workpiece processing. The lithographic tool arrangement groups lithographic tools into clusters, and selectively transfers a semiconductor workpiece between a plurality of lithographic tools of a first type in a first cluster to a plurality of lithographic tools of a second type in a second cluster. The selective transfer is achieved though a transfer assembly, which is coupled to a defect scan tool that identifies defects generated in the lithographic tool of the first type. The disclosed lithographic tool arrangement also utilizes shared structural elements such as a housing assembly, and shared functional elements such as gases and chemicals. The lithographic tool arrangement may consist of baking, coating, exposure, and development units configured to provide a modularization of these various components in order to optimize throughput and efficiency for a given lithographic fabrication process.
