Researchers integrate thin-film pinned photodiode into superior short-wave-infrared imaging sensors

Posted by in categories: electronics, innovation

Imec, a research and innovation hub in nanoelectronics and digital technologies, has presented the successful integration of a pinned photodiode structure in thin-film image sensors.

The report, published in the August 2023 edition of Nature Electronics, is titled “Thin-film image sensors with a pinned photodiode structure.” Initial results were presented at the 2023 edition of the International Image Sensors Workshop.

With the addition of a pinned-photogate and a transfer gate, the superior absorption qualities of thin-film imagers—beyond one µm wavelength—can finally be exploited, unlocking the potential of sensing light beyond the visible in a cost-efficient way.
