An emitted energy system for use in photolithography may include a holder assembly operable to precisely align a diffuser and a nozzle. In accordance with one embodiment of the present invention, a holder assembly (30) may comprise a nozzle mounting system (414) coupled to a housing assembly (400) to secure a nozzle (22). A diffuser mounting system (430) may be coupled to the housing assembly (400) to secure a diffuser (28). An alignment system (450) may operate to align the nozzle (22) and the diffuser (28) in a spatial relationship with each other to optimize operation of the diffuser (28) in relation to the nozzle (22).
摘要:
A four-nozzle plasma generator comprising two anode electrode chambers and two cathode electrode chambers connected to DC power sources and generating four plasma jets of which the shape and the path are determined by an external magnetic field system. The plasma jets converge on a central area into which the material to be processed is injected, in order to form a single plasma stream. The nozzles are symmetrically arranged on a hood which includes a flat water-cooled diaphragm provided with a central aperture.
摘要:
A photolithography tool includes an anode and a cathode composed of a first material and a second material. The second material has a lower work function than the first material. Electrons emitted from the cathode ionize a gas into a plasma that generates EUV light. The EUV light is focused on a mask to produce an image of a circuit pattern. The image is projected on a semiconductor wafer to produce a circuit.

An emitted energy system for use in photolithography may include a fluid nozzle. A nozzle and its method of manufacture are provided. A nozzle (22) may include a nozzle cavity (110) disposed within a nozzle body (100) between an up-stream end (102) and a down-stream end (104). A nozzle passage (118) may be defined within the nozzle cavity (110) and extend a longitudinal length (120) from the down-stream end (104) of the nozzle body (100) into the nozzle cavity (110). A discharge orifice (124) may also be defined at the down-stream end (104) of the nozzle cavity (110) and have an associated width (126). The width (126) of the discharge orifice (124) may be substantially less than the longitudinal length (120) of the nozzle passage (118).
摘要:
A high energy photon source. A pair of plasma pinch electrodes are located in a vacuum chamber. The chamber contains a working gas which includes a noble buffer gas and an active gas chosen to provide a desired spectral line. A pulse power source provides electrical pulses at voltages high enough to create electrical discharges between the electrodes to produce very high temperature, high density plasma pinches in the working gas providing radiation at the spectral line of the source or active gas. Preferably the electrodes are configured co-axially with the anode on the axis. The anode is preferably hollow and the active gas is introduced through the anode. This permits an optimization of the spectral line source and a separate optimization of the buffer gas. Preferred embodiments present optimization of capacitance values, anode length and shape and preferred active gas delivery systems are disclosed. Preferred embodiments also include a pulse power system comprising a charging capacitor and a magnetic compression circuit comprising a pulse transformer. A heat pipe cooling system is described for cooling the central anode.
