Description
Silicon and its technology are the reference points in the sensor/electronics fields. Anyway niche sectors exist where Diamond plays either a competitive or an exclusive role with respect to Silicon. Broadly speaking, sensors placed near the accelerator beams, biological Multi Electrode Arrays (MEA) and neuro-prosthesis applications are such sectors.
In these last years the rise of laser applications to “write” graphite pattern in diamond, the implementation of electronic circuits on diamond and the more recent bonding laser technique between diamond and Si chips are opening new roads for sensor device architecture and their electronics.
All that is the background scenario of the research work we have promoted on Silicon-on-Diamond devices and of which we report the most recent results concerning the production of strip like graphite electrodes on a diamond particle sensor. The employed graphitization technique and the preliminary experimental results are presented. Limits and improvements are discussed together with different electrode and contact geometry applications.
