Why is it not easy to use high resistance on the silicon chip integrated circuit
In some places, the resistance of the epitaxial layer is adopted, and the resistance is N type, which has a lot of inconvenience in the circuit, and the numerical value is also very difficult to do
For boron diffusion resistance, its resistivity is determined by the use of a greater length / width ratio, which is subject to the limitations of process and wafer area
It is not easy to use high resistance on silicon wafer because of the resistance on silicon wafer,
