Abstract: A semiconductor structure includes channel structures vertically stacked, a gate structure engaging the channel structures, an epitaxial feature abutting the channel structures, a backside interconnect layer disposed under the epitaxial feature, and a backside metal contact disposed directly under the epitaxial feature and electrically coupling the epitaxial feature to the backside interconnect layer. In a cross-sectional view of the semiconductor structure along a lengthwise direction of the channel structures, the backside metal contact extends to a position directly under the channel structures.

Abstract: The present disclosure is directed to a modularized vessel droplet generator assembly (MGDVA) including a droplet generator assembly (DGA). Under a normal operation, the liquid fuel moves along an operation pathway extending through the DGA to eject or discharge the liquid fuel (e.g., liquid tin) from a nozzle of the DGA into a vacuum chamber. The liquid fuel in the vacuum chamber is then exposed to a laser generating an extreme ultra-violet (EUV) light. Under a service operation, the operation pathway is closed and a service pathway extending through the DGA is opened. A gas is introduced into the service pathway forming a gas-liquid interface between the gas and the liquid fuel. The gas-liquid interface is driven to an isolation valve directly adjacent to the DGA. In other words, the gas pushes back the liquid fuel to the isolation valve. Once the gas-liquid interface reaches the isolation valve, the isolation valve is closed isolating the DGA from the liquid fuel.

Abstract: A method for using an extreme ultraviolet radiation source is provided. The method includes performing a lithography process using an extreme ultraviolet (EUV) radiation source; after the lithography processes, inserting an extraction tube into a vessel of the EUV radiation source; and cleaning a collector of the EUV radiation source by using the extraction tube.

Abstract: A shielding device includes an upper cover and a lower frame. The upper cover is formed at predetermined positions with a plurality of shielding elements. When the upper cover is closed onto the lower frame, the shielding elements block clearances on the upper cover to effectively stop electric waves from entering into and leaking from the shielding device via the clearances on the upper cover.
