1. Overview

Specialized ICs (Application-Specific Integrated Circuits, ASICs) are customized microchips designed for specific functions or applications, unlike general-purpose ICs. They optimize performance, power efficiency, and size for targeted tasks, playing a critical role in modern electronics such as telecommunications, automotive systems, and AI accelerators.

3. Structure and Composition

A typical Specialized IC includes:

• Semiconductor Substrate: Silicon wafer with CMOS/BiCMOS processes
• Transistor Array: Millions to billions of MOSFETs or FinFETs
• Metal Layers: Multi-layer interconnects for signal routing
• IP Blocks: Pre-designed modules (e.g., ARM cores, DSP units)
• Package: BGA, QFN, or flip-chip for thermal/electrical performance
