Abstract
A semiconductor processing apparatus is provided. The apparatus includes a body portion, which includes at least one semiconductor processing unit. Each semiconductor processing unit includes a recess formed on an upper surface of the body portion, wherein a bottom surface of the recess has at least one location and a peripheral. The bottom surface ascends from the at least one location toward the peripheral against a direction of gravity or descends from the at least one location toward the peripheral following the direction of gravity. Each semiconductor processing unit also includes a first channel that connects to the recess at the at least one location, as well as at least one second channel connecting to the recess at the peripheral. Each of the first channel and the at least one second channel serves as an inlet or an outlet via which a fluid enters or exits the recess. A method according to the present disclosure may control a flowing direction of a fluid flowing across a substrate surface. When the fluid flow as programmed, the fluid may contact the substrate surface and process the surface via various physical and/or chemical reactions.
