Methods and apparatus relating to a very large scale FET arrays for analyte measurements. ChemFET (e.g., ISFET) arrays may be fabricated using conventional CMOS processing techniques based on improved FET pixel and array designs that increase measurement sensitivity and accuracy, and at the same time facilitate significantly small pixel sizes and dense arrays. Improved array control techniques provide for rapid data acquisition from large and dense arrays. Such arrays may be employed to detect a presence and/or concentration changes of various analyte types in a wide variety of chemical and/or biological processes. In one example, chemFET arrays facilitate DNA sequencing techniques based on monitoring changes in hydrogen ion concentration (pH), changes in other analyte concentration, and/or binding events associated with chemical processes relating to DNA synthesis.
与用于分析测量的超大规模场效应晶体管阵列有关的方法和装置。化学场效应晶体管(如 ISFET)阵列可以使用传统的 CMOS 处理技术制造,该技术基于改进的场效应晶体管像素和阵列设计,可提高测量灵敏度和准确性,同时有利于实现显著较小的像素尺寸和密集阵列。改进的阵列控制技术可从大型密集阵列中快速获取数据。此类阵列可用于检测各种化学和/或生物过程中各种分析物的存在和/或浓度变化。例如,化学场效应晶体管阵列可通过监测氢离子浓度(pH 值)的变化、其他分析物浓度的变化和/或与 DNA 合成相关化学过程的结合事件,促进 DNA 测序技术的发展。
