Abstract: A method of manufacturing semiconductor device includes forming a multilayer photoresist structure including a metal-containing photoresist over a substrate. The multilayer photoresist structure includes two or more metal-containing photoresist layers having different physical parameters. The metal-containing photoresist is a reaction product of a first precursor and a second precursor, and each layer of the multilayer photoresist structure is formed using different photoresist layer formation parameters. The different photoresist layer formation parameters are one or more selected from the group consisting of the first precursor, an amount of the first precursor, the second precursor, an amount of the second precursor, a length of time each photoresist layer formation operation, and heating conditions of the photoresist layers. The multilayer photoresist structure is selectively exposed to actinic radiation to form a latent pattern, and the latent pattern is developed by applying developer to the selectively exposed multilayer photoresist structure to form the pattern.

Abstract: The present disclosure is directed to gate-all-around (GAA) transistor structures with a low level of leakage current and low power consumption. For example, the GAA transistor includes a semiconductor layer with a first source/drain (S/D) epitaxial structure and a second S/D epitaxial structure disposed thereon, where the first and second S/D epitaxial structures are spaced apart by semiconductor nano-sheet layers. The semiconductor structure further includes isolation structures interposed between the semiconductor layer and each of the first and second S/D epitaxial structures. The GAA transistor further includes a gate stack surrounding the semiconductor nano-sheet layers.

Abstract: A deposition system provides a feature that may reduce costs of the sputtering process by increasing a target change interval. The deposition system provides an array of magnet members which generate a magnetic field and redirect the magnetic field based on target thickness measurement data. To adjust or redirect the magnetic field, at least one of the magnet members in the array tilts to focus on an area of the target where more target material remains than other areas. As a result, more ion, e.g., argon ion bombardment occurs on the area, creating more uniform erosion on the target surface.
