Reliability and Retention Study of Nanocrystal Cell Array

2002

We have studied nanocrystal memory arrays with 2.56 × 105 cells (256kb) in which Si nanocrystals have been obtained by CVD deposition on a 4nm tunnel oxide. The cells in the array are programmed and erased by electron tunneling through the SiO2 dielectric. We find that the threshold voltage distribution has little spread. In addition the arrays are also very robust with respect to drain stress and show good retention.

Micro and Nano patterns for Biosensing: from enzymatic assays to single cells interaction arrays

2012

In this thesis work, solution dispensing techniques have been employed for the realization of complex biological arrays. Inkjet printing techniques were employed for the generation of drug screening platforms. This approach was initially proved with a model enzyme system like Glucose Oxidase substrate covalently linked to a functionalized silicon oxide support. On this support an enzymatic substrate (D-glucose)/inhibitor (D-glucal) couple was accurately dispensed. A simple optical detection method was used to prove the screening capability of the microarray with the possibility to assay with high reproducibility at the single spot level. Afterwards, this methodology has been extended to CYP…
