Abstract

Abstract

A new type of System-On-Chip (SOC) integrated with ISFET/REFET/PRE and their signal detection circuits is developed. Carring out the basic chip with commercial standard CMOS processes, the preparation technique of sensitivity membrane compatible with the SOC and interrelated follow-up processes are explored, the H+ sensitive Polypyrrole (Ppy) membrane is emphatically studied by electrochemical polymerization; It is compared with the SOC which developed by low temperature Ta2O5 preparation technique. The new SOC has the sensitivity of 54mV/pH, response time of 0.1s, linear correlation coefficient of 99.99% within the pH range from 1 to 12.
