Semiconductors are primarily crystalline materials, such as silicon, with conductivity between insulators and conductors. They are essential for integrated circuits (ICs), transistors, and solar cells.

Introduction to Semiconductors

• Primarily crystalline materials, such as silicon
• Conductivity between insulators and conductors
• Essential for ICs, transistors, solar cells

Silicon wafers were invented in the 1950s for integrated circuit production and standardized in the 1960s with established sizes and quality for semiconductor manufacturing. The 1980s introduced 200mm wafers for better efficiency, evolving today to 300mm+ wafers with advanced tech for chips and PV cells.

History and Production of Wafers

1950s: Invention of Silicon Wafers Silicon wafers invented to enable integrated circuit (IC) production. 1960s: Silicon Wafers Standardized Standard sizes and quality established for semiconductor manufacturing. 1980s: Larger Wafer Diameters Introduced 200mm wafers to boost production efficiency and yields. Today: Advanced Processes for Chips 300mm+ wafers with cutting-edge tech for chips and PV cells.

The slide outlines the Wafer Manufacturing Workflow in a table with phases, owners, and durations. It covers Crystal Formation (several days, Crystal Growth Team) through Final Polishing (15-30 minutes, Polishing Team), with intermediate steps like Slicing & Grinding, Cleaning, and Texturing & Etching.
