An etching agent is a chemical used in the semiconductor etching process to selectively remove or strip away the target film layer, creating a designed pattern. Wet etching is one of the most important techniques used in this process, relying on a chemical reaction between the etching agent and the target film layer to achieve precise results. Each type of film layer has a specifically tailored etchant to ensure optimal performance. Applications Etching agents are primarily used in two key industries: integrated circuit manufacturing and flat panel display production.
Semiconductor developer solutions are chemical mixtures used in the photolithography process to develop photoresist patterns on silicon wafers. These solutions selectively remove exposed or unexposed photoresists, depending on the type used. The developer is a chemical solvent that dissolves the photoresist (PR) produced by exposure. The PR in the photolithography process is mainly divided into positive PR and negative PR, so the developer is divided into positive PR developer and negative PR developer. The positive PR developer is usually a strong alkaline solution diluted with water, which is used in the positive PR development process. The negative PR developer is usually an organic solvent, which is used in the negative PR development process.
Functional electronic wet chemicals refer to specialized chemical compounds formulated through composite technology to meet the unique process requirements in various manufacturing industries. In simple terms, these are ultra-clean, high-purity reagents sometimes a blend of multiple such reagents that are enhanced by adding water, organic solvents, chelating agents, surfactants, and other components. These chemicals play a crucial role in processes like cleaning, lithography, development, etching, and doping in the microfabrication of electronic components, including semiconductors, display panels, and solar cells. Moreover, they can be tailored to suit specific process needs.
LED light.
For the Mosquito killer Led Bulb Light, is a 900 lumen bulb that doubles as an insect killer. The light features a blue UV LED which attracts insects into a Mosquito Killer grid.And the Mosquito Killer grid uses only 1W of electricity, while the light itself uses a meager 9W – and both can be used independently.They are used at home and outdoor. A brush is provided to clean off insects once the bulb switched-off.Compare to other traditional mosquito killer, this bulb has no chemicals, no sprays and hence no fumes to our life. • 2nd generation 2-in-1 LED LIGHT Bulb Plus LED Mosquito Killer Bulb • Wattage: 10W • Blue UV light • Lumen: 900-1000lm • Color Temperature (CCT): 6500K • Input Voltage: AC 90-130V & 220v-240V • With CE and ROHS Operation: Step1: Switch it on,both lighting +killing are on. Step2: Switch on again,light off,only killing on. Step3: Switch on again,killing off,only light on. Step4: Switch off, both off.
