Photolithography Terminology

3. a microfabrication process that uses light to transfer geometric patterns from a photomask onto a light-sensitive chemical called a photoresist
6. a high-precision glass or quartz plate containing microscopic, light-blocking patterns of an integrated circuit or device
7. a sliver of semiconductor material used in electronics
8. critical thermal steps that drive off solvents, crosslink polymers, and stabilize photoresist patterns
9. after photoresists is applied this process removes the exposed substrate beneath
10. a curved, transparent piece of glass or plastic used to refract and focus light
12. a form of electromagnetic radiation that can be perceived by the human eye
15. the process of manufacturing miniature structures, components, and devices with features measured in micrometers (microns) or smaller
17. a chemical solution or mixture used to trigger a specific, visible physical or chemical change
18. the process of projecting a pattern onto a substrate coated with a photosensitive polymer (photoresist)
20. a tiny, flat piece of semiconductor material (usually silicon) that holds thousands to billions of microscopic electronic components

1. a light-sensitive organic polymer used in photolithography and photoengraving to create patterned coatings
2. a precise manufacturing process that uses light-sensitive resist and chemical etchants to remove selected areas of metal, creating intricate, burr-free, and stress-free components
3. the act of creating, copying, or arranging things following a specific sequence, rule, or decorative design
4. a foundational surface, layer, or substance upon or through which a process occurs
5. an invisible form of high-energy electromagnetic radiation found naturally in sunlight
11. a printing method based on the chemical principle that oil and water repel each other
13. advanced, high-precision semiconductor manufacturing machines that transfer microscopic circuit patterns from a photomask onto silicon wafers using light
14. a foundational photolithography technique used to manufacture semiconductors
16. a protective or decorative layer applied to the surface of a material
19. a hard, brittle metalloid and the second most abundant element in the Earth's crust
