Abstract: Systems, apparatuses, and methods are provided for manufacturing an electrostatic clamp. An example method can include forming, during a first duration of time comprising a first time, a top clamp comprising a first set of electrodes and a plurality of burls. The method can further include forming, during a second duration of time comprising a second time that overlaps the first time, a core comprising a plurality of fluid channels configured to carry a thermally conditioned fluid. The method can further include forming, during a third duration of time comprising a third time that overlaps the first time and the second time, a bottom clamp comprising a second set of electrodes. In some aspects, the example method can include manufacturing the electrostatic clamp without an anodic bond.

Abstract: An electrostatic clamp (300) and a method for manufacturing the same is disclosed. The electrostatic clamp includes a first layer (302) having a first ultra-low expansion (ULE) material, a second layer (304) coupled to the first layer, having a second ULE material, and a third layer (306), coupled to the second layer, having a third ULE material. The electrostatic clamp further includes a plurality of fluid channels (316) located between the first layer and the second layer and a composite layer (308) interposed between the second layer and the third layer. The method for manufacturing the electrostatic clamp includes forming the plurality of fluid channels, disposing the composite layer on the third layer, and coupling the third layer to the second layer. The plurality of fluid channels is configured to carry a thermally conditioned fluid for temperature regulation of a clamped object.

Abstract: A method for reducing sticking of an object to a surface used in a lithography process includes receiving, at a control computer, instructions for a tool configured to modify the surface and forming, in a deterministic manner based on the instructions received at the control computer, a modified surface having a furrow and a ridge, wherein the ridge reduces the sticking by reducing a contact surface area of the modified surface. Another apparatus includes a modified surface that includes furrows and ridges forming a reduced contact surface area to reduce a sticking of an object to the modified surface, the ridges having an elastic property that causes the reduced contact surface area to increase when the plurality of ridges is elastically deformed.
