Megapixel CMOS image sensor fabricated in three-dimensional integrated circuit technology

Summary

In this paper a 3D integrated 1024x1024, 8um pixel visible image sensor fabricated with oxide-to-oxide wafer bonding and 2-um square 3-D-vias in every pixel is presented. The 150mm wafer technology integrates a low-leakage, deep-depletion, 100% fill factor photodiode layer to a 3.3-V, 0.35-um gate length fully depleted (FD) SOI CMOS readout circuit layer.

Monolithic 3.3V CCD/SOI-CMOS Imager Technology

Summary

We have developed a merged CCD/SOI-CMOS technology that enables the fabrication of monolithic, low-power imaging systems on a chip. The CCD's, fabricated in the bulk handle wafer, have charge-transfer inefficiencies of about 1x10(-5) and well capacities of more than 100,000 electrons with 3.3-V clocks and 8x8um pixels. Fully depleted 0.35pm SOI-CMOS ring oscillators have stage delay of 48ps at 3.3V. We demonstrate for the first time an integrated image sensor with charge-domain A/D conversion and on-chip clocking.
