1. A supporting device for relative supporting lithography or metrology tools with respect to a base comprising:
- a load side part,a base side part, andan intermediate part giving support to the load side part, and thus defining a support direction with reference to the base side part and the load side part,wherein the intermediate part includes a pressure chamber that is formed by chamber walls to encapsulate a fluid,wherein the chamber walls include a bellow that is deformable in the support direction, and undeformable perpendicular to the support direction, and is located closer to the base side part than to the load side part, andwherein the load side part is connected with the pressure chamber by an elastic hinge that is stiff in the support direction and bendable perpendicular to the support direction.
