ISFET Technology – Various Customers
The Ion Sensitive Field Effect Transistor (ISFET) is a solid state, potentiometric sensor capable of measuring pH in the range of pH 1 to pH 14 with a linear response.
Various customers need customized ISFETs with high sensitivity, low drift, and low light sensitivity; especially now, as replacements are required for the discontinued Honeywell ISFET sensor.
We developed a solution based on ion implantation, gate oxidation, diffusion, and a tantalumoxide (Ta2O5) gate material. The device is customizable and uncalibrated, allowing for full access to the sensor.
