Milestone events and episodes of CCD Development and Commercialization are mainly described during about twenty years from 1969. The technology background after 1920s which has an affect on CCD, and the technology and business trend of image sensors after 1990s up to now, are touched on.
Domain separation and context-aware resource allocation are presented as system design techniques utilizing multi-core processors. Domain separation increases real-time system performance with multiple operating systems on multiple CPU cores. Application QoS technique with sensing user contexts enhances user experience by context-aware resource allocation.
After an overview of the early image sensor technologies, the technological transition in the dawn of Japan is reviewed. Some key examples are picked up and discussed what could be learnt from the history.
This presentation introduces analysis and evaluation on light transmission characteristics through multiple-metal layers of nano-meter CMOS. We have calculated light transmission characteristics using light transmission matrix and evaluated with 12 metal layer 65nm CMOS. We have measured polarization characteristics through metal wire grid, which is well explained by the simple optical model for wire grid polazation.
Development of the CMOS process enables implementation of sub-wavelength structures. To improve the extinction ratio of polarization analyzing image sensor, we designed and fabricated the sensor with fine metal grid polarizers using 65nm CMOS process. By the fabricated sensor, extinction ratio greater than 40 is successfully achieved.
Physical analysis and reduction of random telegraph noise (RTN), which has become a major problem on advanced CMOS image sensor, are strongly required. This report proposes a new method to measure time constants and amplitudes of RTN with high precision and high speed by a large arrayed DUT test circuit based on CMOS image sensor technology. Moreover, we demonstrate some results from analysis of manufacturing process conditions which have strong effects on RTN characteristics.
