Definition
Lithography Metal Manufacturing (LMM) involves the following steps:
- Lithography: A photoresist is applied to a metal surface and exposed to ultraviolet (UV) light through a mask. The exposed areas of the photoresist are then developed, leaving behind a patterned resist mask.
- Metal Deposition: A thin layer of metal is deposited onto the surface of the substrate using a physical vapor deposition (PVD) or chemical vapor deposition (CVD) process.
- Etching: The metal layer is etched using a wet or dry etching process, removing the metal in the areas not protected by the resist mask.
- Resist Removal: The remaining resist mask is removed, leaving behind the patterned metal layer.
Advantages of LMM
- High resolution and precision in pattern formation
- Ability to create complex and dense metal interconnects
- Compatible with various metal materials, such as copper, aluminum, and gold
Applications of LMM
LMM is widely used in the production of:
- Integrated circuits (ICs)
- Printed circuit boards (PCBs)
- Microelectromechanical systems (MEMS)
- Optical components
