Types of crosstalk

 

1) Optical crosstalk

  • Due to photon exchange between neighboring pixel before electron/hole pair generation
  • Mainly appears in back-end, but can also appear in silicon subsrate

 

2) Electrical crosstalk

  • Due to diffusion of electric charge between adjacent pixels
  • Solved after application of FDTI technology

 

3) Spectral crosstalk

  • Only dependent on the color filter design

  • Optical crosstalk and electrical crosstalk becomes more severe as pixel pitch is scaled down
  • Optical crosstalk and electrical crosstalk are pixel architecture dependent
  • Spectral crosstalk is dependent on the angle of incoming light
