| ========== | |
| SKY130 is a mature 180nm-130nm hybrid technology developed by Cypress Semiconductor that has been used for many production parts. SKY130 is now available as a foundry technology through SkyWater Technology Foundry. | |
| The technology is the 8th generation SONOS technology node (130nm). | |
| The technology stack consists of; | |
| - 5 levels of metal (`p` - penta) | |
| - Inductor or Inductor-Capable (`i`) | |
| - Poly resistor (`r`) | |
| - SONOS shrunken cell (`s`) | |
| - Supports 10V regulated supply (`10R`) | |
