Summary: | Systems and methods for cooling an objective lens of a charged-particle beam system are disclosed. According to certain embodiments, the method for cooling an objective lens of a charged-particle beam system comprises receiving a fluid via a fluid input port of a bobbin, circulating the fluid that absorbs heat generated by a plurality of electromagnetic coils of the objective lens, via a plurality of channels distributed in the bobbin, and dispensing the fluid circulated by the plurality of channels via a fluid output port of the bobbin. The bobbin may further comprise a bottom flange proximal to a wafer and a top flange distal from the wafer. The bobbin having the plurality of channels may comprise an additively manufactured monolithic structure. |
