Definition

A special type of mask used in the process of creating microcircuits, which allows light to pass through specific patterns to transfer images onto a surface.

Example

The engineer carefully aligned the photomask with the silicon wafer to ensure accurate pattern transfer.

Conversation

Have you ever worked with a photomask in your projects?

No, I haven't, but I've heard they're crucial for making circuits.

Yeah, they help transfer patterns onto the surface of the chips.

That sounds interesting! I’d love to learn more about how they work.

Root Explanation

Photomask → It is formed from "photo-" (from Greek "phōs", meaning light) and "mask" (from Old French "masque", meaning a covering or disguise). The word "photomask" refers to a mask used in photolithography to project light patterns onto a surface.

Memory Tip

Think of 'light' ('photo-') being used to create patterns on a 'mask' — that's how a photomask works in technology.
