One of the latest Sony patents disclosed a new kind of sensor. Pixel size does change based on their color characteristic. This does make sense because every color has a different sensivity. Read the google english translation:

Patent publication number 2010-129548
- 2010/06/10 Release date 2010/06/10
- 2008/11/25 Filing Date November 25, 2008
Current Issues
- The signal level is smaller and more pixelated, S / N ratio is difficult to ensure
- RGB wavelengths the energy profile for each file is different
  - Color imbalance
Patent Technology
- Energy profiles corresponding to the active area (pixel size) and
- Long wavelength light (Red) is a large photodiode (detector sensors) and
  - Silicon on the substrate, R is the weakest of the irradiation energy
  - RGbGrB square fit to
