According to research by TrendForce, the shipment volume of smartphone camera modules in 2022 will be raised to 5.02 billion units, an annual increase of 5%. Since the price-performance ratio of the whole machine is the main basis for consumers to buy, the three-lens design is still the mainstream design this year, and it is estimated that it will account for more than 40% of the overall shipment.



By combining a high-pixel main lens with two low-pixel functional lenses, the mobile phone can maintain a three-lens design and take into account the hardware cost. This is also the main reason for the development of mid-to-low-end products towards three-lens or even four-lens designs.


The growth momentum of mobile phone camera module shipments in 2022 is mainly due to the increase in the number of low-pixel lenses driven by the three-lens design. Although the high-pixel main lens with better specifications can enable brand manufacturers to provide better mobile phone shooting performance, due to Pixel specifications have not continued to climb to a higher level, and are still maintained at around 50 million pixels, which has caused demand to stagnate slightly.

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

Semiconductor devices

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

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

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.
