Start with the fundamentals of semiconductor physics. Learn about the behavior of electrons and holes in semiconductor materials, band theory, and energy levels.
Understand key semiconductor properties such as conductivity, resistivity, electron mobility, and intrinsic and extrinsic semiconductors.
Types of Semiconductors:

Differentiate between intrinsic and extrinsic (doped) semiconductors. Study how doping with specific impurities (n-type and p-type) affects conductivity.
Diode Theory:

Explore the theory behind diodes, which are essential semiconductor devices. Learn how diodes work, their voltage-current characteristics, and how they rectify AC signals.
Transistor Theory:

Understand the operation of bipolar junction transistors (BJTs) and field-effect transistors (FETs), which are the core components in many electronic circuits.
Study transistor configurations (common emitter, common base, common collector for BJTs; common source, common gate, common drain for FETs) and their amplification properties.
Semiconductor Fabrication:

Learn about semiconductor manufacturing processes, including crystal growth, wafer fabrication, doping techniques, and lithography. Understand how integrated circuits (ICs) are manufactured.
PN Junctions:

Deepen your knowledge of PN junctions, which are crucial in semiconductor devices. Study their formation, depletion regions, and rectifying behavior.
Semiconductor Materials:

Familiarize yourself with common semiconductor materials, such as silicon (Si) and gallium arsenide (GaAs). Understand why silicon is widely used in the electronics industry.
