“…(23) A 0.18 μm process rule was used in several studies between 2010 and 2014. Chan et al, (24) Shields et al, (25) and Huang et al (26) (27) The feasibility of an array with a huge number of pixels at a high density and the possibility of fast data readout with a high frame rate are the main advantages of an IS-FET array.…”

A chemical imaging sensor is a field-effect-based semiconductor sensor, capable of label-free imaging of ion distributions in a solution. The sensor has attracted much interest owing to its simple structure and diverse fields of application of bioimaging. In this article, the principle and development of the chemical imaging sensor are summarized, compared with those of other labelfree imaging sensors. Bio-imaging applications of the chemical imaging sensor to ion diffusion, enzymatic reaction, and metabolic activities of microorganisms are also reviewed.

“…In particular, the array image sensor requires a dense, reliable and scalable ISFET array that enables massive parallelism and high throughput [13]. Recently, several array image sensors were reported including 32 × 32 (1k) pixels and 9.3 frame/s (fps) image sensor [14]; 512 × 576 (300k) and 375 fps image sensor [15]; 3600 × 3600 (13M) and 26 fps image sensor [16]. The number of pixels and fps is increasing, and the spatial resolution is also improving.…”

A semiconductor array pH image sensor consisting of four separated blocks was fabricated using charged coupled device (CCD) and complementary metal oxide semiconductor (CMOS) technologies. The sensing surface of one of the four blocks was Si3N4 and this block responded to H+. The surfaces of the other three blocks were respectively covered with cation sensitive membranes, which were separately printed with plasticized poly (vinyl chloride) solutions including Na+, K+, and Ca2+ ionophores by using an ink-jet printing method. In addition, each block of the image sensor with 128 × 128 pixels could have a calibration curve generated in each independent measurement condition. The present sensor could measure the concentration image of four kinds of ions (H+, K+, Na +, Ca2+) simultaneously at 8.3 frames per second (fps) in separated regions on a chip.

“…In order to solve the above issues, we proposed, for the first time, a pH-to-timeto-voltage converter (pH-TVC) (our works from [83,89,90]), where a sub-threshold ISFET is employed, as shown in Fig. 3.7(b).…”

“…In order to study and characterize ISFET properties, the 512×576 pixel array is divided into several sub-arrays with source-follower or pH-TVC readout circuits, with different ISFET chemical sensing areas or transistor sizes, and so on (our works from [83,89,90]).…”
