State of the art technologies for front-end hybrids

The front-end hybrids for solid state and gas detectors will be crucial components of the next generation particle detectors. Requirements such as high-density and high-speed interconnects, low mass, radiation resistance, high-current and high-power dissipation capabilities are examples of the challenges to be solved concurrently. The technologies for front-end hybrids developed at CERN are presented and future possibilities such as embedding active and passive circuits are described. Comments are made concerning the ability to use these technologies for large scale production by industry
