Metals　with　well　ordered　porous　networks　exhibit　interesting　electronics,　photonics　and　antimicrobial　properties,　but　fabrication　of　ordered　porous　metal　by　sputtering　deposition　is　difficult.　A　new　method　to　develop　arrayed　nanoporous　multilayered　films　in　the　Ag/W　system　has　been　reported　in　this　work.　The　results　show　that　the　structure　of　the　multilayers　is　dependent　on　the　periodicity.　Multilayers　with　periodicity　not　larger　than　30　nm　have　an　arrayed　porous　structure.　The　formation　of　the　porous　structure　can　be　ascribed　to　the　initial　Volmer-Weber　growth　due　to　the　large　positive　enthalpy　of　mixing　Ag　and　W　and　the　following　shadowing　effect　during　alternate　sputtering　deposition.　This　method　gives　a　controllable　way　to　fabricate　nanoporous　binary　immiscible　metal　films.
