🧱 2.1 Silicon Wafer (Base Material)

The silicon wafer is the foundational part used in making a chip. It acts as the substrate on which electronic circuits are built.

Why Silicon?

• Abundant & cost-effective
• High thermal conductivity
• Excellent semiconductor behavior

Wafer Sizes

Wafer Diameter	Usage	Cost Impact
150 mm	Legacy systems	Low
200 mm	Industrial electronics	Medium
300 mm	Advanced processors	High

Modern fabs (like TSMC & Samsung) use 300 mm wafers for cutting-edge chips.

⚡ 2.2 Doped Regions / Transistors

Transistors are the switching elements of a chip. A modern processor can contain billions of them.

Core Elements:

• Source
• Gate
• Drain
• Oxide layer

Doping (adding impurities like phosphorus or boron) changes silicon’s conductivity, forming N-type and P-type regions.

Why this part matters:
Transistors determine power efficiency, speed, and reliability—critical for smart grid and IoT devices.
