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.

As China's laser industry continues to undergo the process of localization, with significant improvements in the quality of domestic products, the domestic market share of laser products, including high-power laser equipment, light sources (fiber lasers, ultrafast lasers, etc.), optical components, control systems (chips, control software, and accessories), and crystal materials, has been steadily increasing in the past two years.

According to data released by the General Administration of Customs, the total import and export value of "lasers, excluding laser diodes" in China from January to June 2023 amounted to 9.229 billion yuan, a 2.42% decrease compared to the same period last year. The import value was 6.859 billion yuan, a 12.05% decrease year-on-year, while the export value was 2.37 billion yuan, a 19.16% increase year-on-year.

Although China still relies heavily on imports for high-end equipment, the industry of laser processing machines for various materials has made significant progress in the past six years. Domestic companies have increased their exports and actively explored overseas markets, entering a favorable development stage. With policy support, important conditions have been created for the development of high-end equipment in the industry.

Arrayed fibers are a special type of fiber structure composed of multiple individual fiber bundles arranged together in an array. Each individual fiber bundle has its own transmission channel and can independently transmit optical signals.

Arrayed fibers play important roles in many applications:

Fiber Optic Sensing: Arrayed fibers can be used as building units for fiber optic sensors. By using multiple fiber bundles, it is possible to simultaneously monitor and measure physical quantities at multiple locations, such as temperature, strain, pressure, etc. Arrayed fiber sensors have the advantage of high sensitivity and multi-channel measurement.

Medical Field: Arrayed fibers find widespread use in medical imaging and diagnosis. They can be used to construct high-resolution fiber optic coherence tomography (OCT) systems and fiber optic microscopes for real-time observation and diagnosis of tissue and cellular structures.

Industrial and Scientific Applications: In industrial and scientific research fields, arrayed fibers can be used for applications such as spectroscopy analysis, laser processing, and optical measurements. Arrayed fibers with multiple channels can provide a larger sampling range and higher data processing capability.

What is biochemical analysis? 

Biochemical analysis refers to the detection method of enzymes, carbohydrates, lipids, protein and non-protein nitrogen, inorganic elements, liver function and other indicators in the body through various biochemical reactions. It is mainly used in routine testing in hospitals. 

Biochemical diagnosis developed earlier in my country and is a routine diagnostic testing item in hospitals, focusing on disease monitoring that has already occurred. 

At present, the domestic biochemical diagnostic reagent market is relatively mature, with a complete range of reagents. Domestic brands have occupied about two-thirds of the domestic biochemical diagnostic reagent market by virtue of the advantages of cost-effective products and high-quality market services. 

What is an immunoassay? 

Immunoassay is a highly selective diagnostic method established by using the specific reaction between the substance to be tested and its corresponding substance. It is often detected by the immune reaction of antigen and antibody, and various carriers are used to amplify the reaction signal to enhance the detection. Sensitivity (labels include isotopes, enzymes, chemiluminescence substances), including radioimmunity, enzyme-linked immunity,  chemiluminescence, etc., mainly to test small molecular proteins, hormones, fatty acids, drugs and other substances in the body, commonly used in infectious diseases, endocrine Detection of protein targets such as diseases, tumors, pregnancy tests, blood group antigens, etc. 

At present, high-end chemiluminescence has gradually replaced ELISA as the mainstream immunodiagnostic method in my country, focusing on the monitoring of infected diseases. 

ELISA: ELISA markers are enzymes, which are often used to detect an antigen or antibody. Reagents have the characteristics of low cost and large-scale operation, and are currently the mainstream of domestic immunodiagnostic reagents. 

Chemiluminescence: Chemiluminescence reagents have high sensitivity, strong specificity, and good reproducibility. They can be used for highly automated semi-quantitative and quantitative analysis, and have fast detection time and good reproducibility. It is one of the important development directions of immunological reagents.

According to the latest report from IC Insights, a well-known market research institution, the total installed capacity of global semiconductors will reach 263.6 million 8-inch equivalent wafers this year, a year-on-year increase of 8.7% and a record high.

The increase in semiconductor production capacity this year is mainly due to the new large-scale memory factories of SK Hynix and Winbond, as well as the active expansion of TSMC, including the capacity growth of two advanced 5nm and 3nm processes, and the expansion of 28nm process capacity in Nanjing. TSMC is forecasting capital expenditures of more than $40 billion this year.

In the past five years, the annual growth rate of global semiconductor production capacity has increased from 4.0% in 2016 to 8.5% in 2021.

Despite inflationary pressures, ongoing supply chain issues and other economic difficulties, semiconductor demand is strong, with shipments set to grow 9.2% year over year this year. Even with 10 new fabs coming into use this year, capacity utilization could reach a high of 93% this year, slightly lower than 93.8% in 2021.

The historical statistics of IC Insights show that the growth rate of semiconductor production capacity shows a certain periodicity, with the first negative growth in 2002, and a relatively large negative growth of -6% in 2009; then it entered a boom period, which has continued to this day. The first two negative growths were the end of the dot-com bubble crisis and the global financial crisis.
