Abstract
Official abstract text for this publication.
Methods and apparatus relating to FET arrays for monitoring chemical and/or biological reactions such as nucleic acid sequencing-by-synthesis reactions. Some methods provided herein relate to improving signal (and also signal to noise ratio) from released hydrogen ions during nucleic acid sequencing reactions.
First claim
Opening claim text (preview).
What is claimed is: 1. A chemically-sensitive field effect transistor (chemFET), comprising: a substrate including a semiconductor well, wherein the semiconductor well has a conductivity type opposite that of the substrate; a gate dielectric on the semiconductor well; a floating gate structure disposed over the gate dielectric; a passivation layer over the floating gate structure; a first diode connected between the floating gate structure and the semiconductor well, where…
