Write what each word means, using the article.

Do not copy the article. Write two things you learned, the way you would explain them to a friend.

Answers below are taken from the article’s stored facts, so they match what the student read.

1. Who invented Integrated circuit?1958
2. What is the primary semiconductor material?Silicon (Si)
3. What is the key technological principle?Monolithic integration of electronic components on a single substrate
4. Why are integrated circuits important?Integrated circuits make devices smaller, faster, and cheaper. They help computers, phones, the internet, and even medical machines like pacemakers work better.
5. How are integrated circuits made?Making an integrated circuit is like building a city on a tiny wafer of silicon. Workers use ultraviolet light to draw patterns, then cut away parts, add special atoms to change how the silicon behaves, and layer metal and insulation to connect everything. The steps are repeated many times to create a 3‑dimensional structure.

Monolithic Integrated Circuit: An electronic circuit whose components are fabricated on a single piece of semiconductor material.
Moore's Law: An observation that the number of transistors on an integrated circuit doubles approximately every two years.
CMOS (Complementary Metal-Oxide-Semiconductor): A widely used technology for manufacturing integrated circuits known for low power consumption.
Photolithography: A process used in microfabrication to selectively pattern parts of a thin film or the bulk of a substrate.
