Dear colleague, On behalf of the Program Committee of the Pixel 2008 Workshop, we invite you to the 2008 meeting of the Pixel Workshop series http://conferences.fnal.gov/pixel2008/ . The workshop will be held at Fermilab, Illinois, USA, from Tuesday, September 23 through Friday September 26. The workshop is open to anyone interested in pixel technology. Technologies for current and future experiments in high energy physics, nuclear physics, particle astrophysics and imaging will be covered, as well as pixel technologies for light sources. The workshop will cover pixel electronics and sensors, high density detector processing and interconnect technologies -- notably the stacked 3D integrated technology -- hybridisation techniques and power issues. All sessions will be plenary and will consist of invited overview talks, followed by shorter presentation. The submission of abstracts closes on July 15, 2008. For the program committee Marcel Demarteau (Fermilab) Simon Kwan (Fermilab)
