| Summary: | The goal to achieve low microwave attenuation loss in a high-speed wireless
communication system is crucial for the advancement of technology evolution.
Background carrier and parasitic surface conduction hinder the progression of a wireless
system to perform better. Recently, a new method using deep-level doping compensation
with the gold element to create high resistivity silicon substrate for microwave application
is successful. Currently, there is no existing equivalent circuit model and mathematical
equations to classify capacitance-voltage characteristic for a metal-oxide structure on
gold-compensated high resistivity silicon substrate. An investigation of capacitancevoltage
characteristics for the metal-oxide-semiconductor structure on low resistivity,
high resistivity and gold-compensated silicon substrates are carried out. The suitable
mathematical equations to represent capacitance-voltage curves of low resistivity silicon
is evaluated. High resistivity silicon equivalent circuit models for low and high
frequencies are determined in MATLAB and verified in SILVACO. The equivalent
circuit models and equations of high resistivity silicon are determined successfully.
Experimental data of Au-compensated high resistivity silicon is compared and analysed
with theoretical high resistivity silicon data. Based on the comparison result of both C-V
curves, the equivalent circuit of gold-compensated high resistivity silicon is not same as
the high resistivity silicon. |
