Abstract

We present a CMOS chip with a 64x64 array of high-density pixels designed for recording electrical signals from cells and stimulating them. A high spatial resolution can be achieved, since the pixels have a pitch of 12.5 µm. Each pixel incorporates a floating-gate-field-effect-transistor with a 4.4 µm x 4.4 µm electrode coupled to its gate. The remaining components of the measurement setup required to operate the CMOS chip are also introduced. A simple post-process, required to deposit a thin film high-k (multilayers of TiO2 and HfO2) material on the chip was developed after the fabrication of the chip and is also introduced here.
