This　paper　is　concerned　with　a　stability　problem　for　compressible　Navier-Stokes-Poisson　systems.　It　arises　in　the　modeling　of　semiconductors　with　a　viscosity　term　in　momentum　equations.　We　prove　that　smooth　solutions　exist　globally　in　time　near　the　steady-state　solution,　and　converge　to　the　steady　state　for　large　time.　In　this　stability　result,　we　don＇t　give　any　special　assumptions　on　the　given　doping　profile.　The　proof　is　based　on　the　techniques　of　anti-symmetric　matrix　and　an　induction　argument　on　the　order　of　the　space　derivatives　of　solutions　in　energy　estimates.　(C)　2018　Elsevier　Inc.　All　rights　reserved.
