摘要:

报道了一种含微参比电极的差分结构,并可与其它敏感元和信号处理电路完全隔离的背面引线氢离子敏感场效应(pH-ISFET)新结构。基于硅的固相键合技术和硅微机械加工技术以及常规N阱MOS工艺,研制成集成压力/pH-ISFET传感器,设计制作了高稳定的可调芯片自恒温系统,经实际工艺流水制成了样管,初步的测量结果证实了这种背面引线、微参比电极、全集成的新结构设计是成功的。

Abstract:

A novel backside contact dual pH-ISFET structure with its microreference electrode which can be completely isolated from other sensitive elemcnts and signal conditioning circuits is presented in this paper.Based on the silicon bonding method, silicon micromechanical technique and standard N-well biMOS compatible process,an integrated pressure/pH-ISFET sensor is developed.A highly stsble Chip-Temperature-Constant system is also designed and developed.Measurement prove;the possibility of the new structure and good characteristics of the sensor.
