Doubt in semiconductor sensors

In summary, a semiconductor sensor is a small, lightweight sensor made from materials with semiconductor properties. It works by converting physical or chemical changes into electrical signals for measurement and analysis. The advantages of using semiconductor sensors include high sensitivity, fast response time, and low power consumption. However, their accuracy can be affected by factors such as material quality, design, and calibration process. Environmental factors can also impact their performance, and they may have limitations such as a limited measurement range and susceptibility to aging and contamination. Regular calibration is necessary to maintain accuracy.

Planar technology: working the silicon wafer surface by repeating a series of basic operations.

Heat treatment: diffusion, oxidation, tempering.
Deposition: CVD, epitaxy, evaporation.
lithography: definition of geometry.
chemical attacks: dry and wet for the selective removal of material.
doping: ion implantation and diffusion.
etc. etc.

These are the common procedures for the preparation of an integrated circuit.
