Publisher's Synopsis
Photon sources enable the extension of lithography and metrology technologies forcontinued scaling of circuit elements and therefore are the key drivers for the extensionof Moore's law. This comprehensive, 28-chapter volume is the authoritative referenceon photon source technology and includes contributions from leading researchers andsuppliers in the photon source field. It is intended to meet the needs of bothpractitioners of the technology and readers seeking a thorough introduction to EUVphoton sources and their applications.
Topics include a state-of-the-art overview and in-depth explanation of photons sourcerequirements, fundamental atomic data and theoretical models of EUV sources basedon discharge-produced plasmas (DPPs) and laser-produced plasmas (LPPs), a descriptionof prominent DPP and LPP designs, and other technologies for producing EUV radiationat 13.5 nm. Additionally, this volume contains detailed descriptions of 193-nm excimerlasers, UV lamps, and laser-driven plasma sources for UV photons, all of which powermany current lithography and metrology tools. CO2 lasers and 1-?m Nd-YAG lasers, usedfor pre-pulse in Sn LPP EUV sources, are also covered.
Alternative photon sources for 13.5-nm lithography and metrology, such as highharmonicgeneration (HHG) and synchrotrons, along with their usage as a metrologytool, are discussed; and potential future photon sources such as free-electron lasers(FELs), solid-state 2-?m thulium lasers, and 1-?m Nd-YAG lasers are described.Additional topics include EUV source metrology, plasma diagnostics of EUV plasmas,grazing and normal incidence collector optics for plasma sources, debris mitigation, andmechanisms of component erosion in EUV sources.
