Samsung Semiconductor Explains Photo Lithography and EUV in 5 Minutes
Like a camera that captures scenes on film with light,
photo lithography is the process of drawing patterns on a wafer. 📸
However, as the size of the pattern to be drawn gets smaller and smaller, the photo lithography reaches its limit.
That’s where the ‘EUV’ comes in.
EUV is an ultra-precise technology that utilizes plasma, more than just a simple light.
Let’s find out more about it with Samsung Semiconductor in just 5 minutes! 🧐
