Color Filters

Structural color filters, which obtain color selection by varying structures, have attracted extensive research interest in recent years due to the advantages of compactness, stability, multifunctions, and so on. In general, the mechanisms of structural colors are based on the interaction between light and structures, including light diffraction, cavity resonance, and surface plasmon resonance. This paper reviews recent progress of various structural color techniques and the integration applications of structural color filters in CMOS image sensors, solar cells, and display.

Color Filters

The trend in the development and manufacturing of Complementary Metal Oxide Semiconductor (CMOS) image sensors is to miniaturize pixels on the chips and hence to improve their imaging characteristics by providing a higher image resolution. As CMOS technology scales down into submicron regions, the conventional color filters are no longer suitable for generating the desired optical density. The major drawback of the conventional color filters produced from pigment-based positive tone photosensitive compositions, is the heterogeneous dispersion of pigments in photoresist composition resulting in color irregularities due to coarse particles of the pigments. One of the most perspective ways to solve this problem is a replacing the pigment with a dye as a coloring agent and thus, increasing solubility of the latter to obtain a homogeneous colored photoresist composition. In this paper, several novel red dye-containing materials are synthesized and tested to provide a redcolored photosensitive composition. This red-colored photosensitive composition is very promising for application as color filters for CMOS image sensors with high resolution and high level of integration architecture.

This work fits the measured in-pixel source-follower noise in a CMOS Quanta Image Sensor (QIS) prototype chip using physics-based 1/f noise models, rather than the widely-used fitting model for analog designers. This paper discusses the different origins of 1/f noise in QIS devices and includes correlated double sampling (CDS). The modelling results based on the Hooge mobility fluctuation, which uses one adjustable parameter, match the experimental measurements, including the variation in noise from room temperature to –70 °C. This work provides useful information for the implementation of QIS in scientific applications and suggests that even lower read noise is attainable by further cooling and may be applicable to other CMOS analog circuits and CMOS image sensors.
