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. What is the process type?Low-temperature, vacuum-based ion beam bombardment for material modification
2. What is the primary industrial application?Semiconductor device fabrication (doping, gate oxide modification)
3. What is ion implantation and why is it used in making computers?Ion implantation is a process that shoots tiny charged particles into a material to change its properties. It lets scientists put special atoms deep inside a chip at precise spots, which helps make tiny electronic parts work.
4. How do the ions know how deep to go into the material?The depth depends on how fast the ions are moving and what kind of atoms they are. Faster ions or heavier atoms go deeper, while slower ones stay near the surface.

Ion Source: Device that generates a beam of charged atoms or molecules for implantation.
Doping: Introducing impurities into a semiconductor to change its electrical conductivity.
Amorphization: The process of destroying the ordered crystalline structure of a material.
