Laser welding is a technology that uses the heat generated by a laser beam to melt plastic contact surfaces, thereby bonding thermoplastic sheets, films or molded parts together. Laser welding technology can be useful when the plastic parts being bonded cannot withstand vibration, or when water and air tightness is very high, or when a sterile and dust-free environment is required (such as medical devices and food packaging). Laser welding technology is fast, especially suitable for the assembly line processing of automotive plastic parts. In addition, for those complex geometries that are difficult to bond using other welding methods, laser welding technology can be considered.

Laser welding is a joining solution that enables clean, particle-free joining. Laser welding can join various materials together. Laser welding technology has evolved as products continue to evolve, shrink in size, and achieve higher standards of performance.

Laser welding is often used in applications that require particle-free connections and fast lead times. Bends and defective parts can be laser welded, and complex shapes and parts can be pre-assembled prior to laser welding. The laser welding process causes no movement or vibration during the welding cycle, so it can be used to weld delicate internal components.

Laser welding plastic technology is a very specialized bonding technology. When high-speed welding and precision welding or aseptic welding are required, this can give full play to the best advantages of laser welding. The main application areas of laser welding technology are medical, automotive, electronics and packaging.

Fundamentals of Lithography

Figure 1 shows a typical lithography process for defining shallow trench isolation features. This process includes the following steps:

1. Substrate Cleaning and Preparation

2. Form a thermal oxide layer and deposit a layer of silicon nitride on a clean substrate

3. Deposit a carbon hard mask followed by a layer of anti-reflection material

4. Deposit a layer of photoresist

5. Pre-baked photoresist

6. Align the substrate/resist and reticle and expose the photoresist using UV radiation and 4x-5x imaging. Repeat steps and scan

7. Post-exposure bake

8. Develop pattern in photoresist and hard bake to remove residual solvent

9. Perform an etch to open the Dielectric Anti-Reflection Coating (DARC) and hardmask patterns, and remove the photoresist and DARC

10. Perform an etch to open trenches in the substrate and remove the hardmask

11. Clean the surface

Deep UV Lithography

DUV technology for lithography is entirely based on projection optics, as the pattern on the photomask is much larger than the final pattern formed on the photoresist. The optical system in a 193 nm lithography tool is called a catadioptric system. The term means it uses lens (refractive) and reflective (reflection) elements to direct and condition the light from the laser

Extreme UV Lithography

EUV lithography is being developed to meet single-exposure patterning requirements for sub-22nm feature sizes (Figure 3). What makes this technology unique is the nature of the light source. See Extreme UV Lithography for more information.
