“…The coating might also be applied on the streets between pixels, or between a grid and a pixel if grid was available. Solder mask had been proven to be a beneficial and reliable coating for CZT detectors [4]. Chemical passivations were processed through oxidations before coating.…”

“…Significant progresses have been made in house on crystal growth, device fabrication, and characterization of CdZnTe (CZT) radiation detectors for imaging applications during the last few years [1][2][3][4][5]. Due to sensitive physical and electrical properties of CZT materials and to varieties of detector dimensions and anode pixel patterns, attachment of pixellated detectors to readout print circuit boards (PCB) is a field required further research.…”

This paper presented a new carrier board attachment method for pixellated CdZnTe (CZT) radiation detectors by using a special type of anisotropic conductive film (ACF) based on micro-wires. This ACF has very small pitch, high vertical electrical conductivity, and strong mechanical strength. It was found to be suitable for pixellated CZT detector assembly by optimizing detector fabrication processes and attachment conditions. ACF attached detector modules showed excellent spectra responses. Long-term stability and reliability tests on these detectors showed promising results. This ACF attachment technology had been successfully used for pixellated CZT detectors with various physical dimensions and anode pixel patterns.
