—A hybrid CMOS/thin-film microsystem for fluores-cence contact imaging is presented. The microsystem integrates a high-performance optical interference filter and a 128 128 pixel active pixel sensor fabricated in a standard 0.35-m CMOS technology. The thin-film filter has an optical density greater than 6.0 at the wavelength of interest, providing adequate(More)
— A hybrid thin film/CMOS microsystem for fluores-cence contact imaging is presented. The microsystem integrates a high-performance optical filter and a 128x128-pixel imager fabricated in a 0.35µm technology. The thin-film filter is fabricated and characterized prior to assembly. Its optical density (OD) is over 6.0 at the wavelength of interest. The(More)
—A hybrid CMOS-microfluidic microsystem for chemi-luminescence and electrochemiluminescence-based biochemical sensing is presented. The microsystem integrates a two-layer soft polymer microfluidic network and a CMOS imager fabricated in a standard 0.35-m technology. The CMOS imager consists of a 64 128-pixel array interdigitated with a 32 64 electrolessly(More)
