| 摘要 |
The present invention provides a micro sensor for monitoring the cleaning and drying processes of surfaces of dielectric films, micro features in porous dielectric films and biologic or other cells common in microelectronics fabrication, MEMS fabrication or microbiology test system fabrication. By embedding electrodes in the surface of a supporting dielectric, the sensor can probe the surface and pores of a covering dielectric or a cell on the covering dielectric. The addition of a guard reduces the effects of any parasitic capacitance, which extends the measurement bandwidth of the sensor and allows it to be manufactured at the scale of a single cell, a feature that is particularly important for applications in microbiology.
