Turchetta 3 April 2003 International ECFA/DESY Workshop Amsterdam, 1-4 April 2003 CMOS sensors design in RAL Goal: to design science-grade sensors. for Particle Physics, Space Science, This requires: full-custom designed tailored to specific applications new designs Good imaging performances CMOS sensor technologies Many foundries propose three flavour of a given technology: digital, analogue and image sensors At present we are using a CMOS Image Sensors (CIS) 0.25 m process low leakage current, low number of defects, good sensitivity to the whole spectrum of light (absorption length for red a few m) thick epitaxial layer (8 m) integration of colour filters, microlenses Up to 5 metal layers for complex routing Metal-to-metal capacitors for precise analogue design Dual power supply: 2.5/3.3 V. Good for low power consumption and good analogue performances Multiple choice of transistors Vt gives more flexibility to the designer
