Comparison of the advantages and disadvantages of the wet and dry etching methods

Comparison of the advantages and disadvantages of the wet and dry etching methods: The wet cleaning system is suitable for advanced non-destructive megasonic cleaning. It can be used to make easily damaged substrates with or without patterns, including templates with protective films. In order to achieve a good cleaning effect while ensuring that the substrate is not damaged, the megasonic energy density must be kept slightly below the damage threshold at any position on the sample. The wet etching technology makes the surface acoustic energy of the substrate evenly distributed, increases the distributed energy to support ideal cleaning, and ensures that it is within the damage threshold of the sample. The system has high repeatability, good uniformity, Z-level advanced megasonic cleaning function, and megasonic assisted photoresist stripping and wet etching functions. The product can be subjected to non-destructive testing, chemical reagent cleaning, brush cleaning, drying, etc. according to the process steps. Comparison of the advantages and disadvantages of the two wet and dry etching methods: The wet etching system is an etching method in which the chemical reaction between a chemical etching solution and the object to be etched makes it peel off. Wet etching is mostly isotropic etching, which is not easy to control. Features: Strong adaptability, uniform surface, little damage to silicon wafers, suitable for almost all metals, glass, plastics and other materials. Disadvantages: The drawing quality is not ideal, and the small lines in the drawing are difficult to grasp. The etching medium of the dry etching system is plasma, which uses plasma to react with the surface film to generate volatile substances, or directly bombard the surface of the film to etch it. Characteristic: It can realize anisotropic etching to ensure the fidelity of the image after the detail conversion.

Plasma surface modification of bast fiber in atmospheric plasma cleaning equipment

Plasma surface modification of bast fiber in atmospheric plasma cleaning equipment: During the plasma treatment of fibers and polymers by the atmospheric plasma cleaning equipment, the high-energy particles and photons generated by the plasma interact violently with the surface of the substrate, and this interaction usually manifests as a free radical chemical reaction. Generally, four surface effects can be observed, namely, surface cleaning, surface etching, molecular cross-linking near the surface, and changes in surface chemical structure. To a certain extent, each effect may exist, but one of the effects may be more obvious than others, depending on the processing object, the chemical properties of the gas, and the instrument model and the settings of the instrument parameters. Several surface effects, alone or in synergy, will affect the adhesion of the processed object. Plasma treatment of atmospheric plasma cleaning equipment has a very good effect on improving the bonding strength between polymer and fiber and between polymer and polymer. The increase in adhesion after plasma treatment is due to the increase in the wettability of the substrate and the change in the chemical structure of the polymer surface after treatment. The gas generates a plasma medium under the coupling action of electromagnetic force. This plasma medium contains ions, electrons, neutrons, photons, free radicals, metastable excited particles and molecules, and dynamic mixing at room temperature. Plasma treatment can make The surface of fibers and textiles is functionalized without affecting their overall performance. Under the action of electromagnetic field, these plasma particles diffuse into the surface of the fabric substrate in a gradient, resulting in a variety of general surface treatments, including surface activation of active sites due to bond breakage, grafting of chemical structures and functional groups, and material volatilization Removal (etching), surface contaminants or layer dissociation (cleaning), and deposition of conformal coatings, etc. The electron collision and photochemical molecular separation of atmospheric plasma cleaning equipment will generate plasma containing high-density free radicals, which can cause the chemical bonds on the surface of the fiber polymer to break, thereby forming new chemical substances on the surface of the fiber polymer. This will lead to changes in the chemical structure and morphology of the fiber surface. The specific surface area of ​​the fiber will increase significantly. Plasma treatment on the surface of fibers and polymers will lead to the production of new functional groups such as hydroxyl (-OH), aldehyde (-CHO) and carboxyl (-COOH), which affect the moisture absorption of the fabric and facilitate the grafting of molecules deal with. The unique physical and chemical properties and temperature range characteristics of plasma. Make it an effective tool for surface treatment of materials. The low-temperature plasma treatment of atmospheric plasma cleaning equipment can improve the dyeing rate, dye uptake and color yield of linen fabrics. The etching and oxidation of the hemp fiber surface reflects the effect of plasma treatment. For fiber products with low color fastness, low-temperature plasma dyeing can be considered. Satisfactory dyeing results can usually be obtained. Plasma treatment can achieve effects that cannot be achieved by conventional treatment. Plasma can only act on the surface of the substance (the upper layer) instead of the entire material. The high cost of the treatment process can be repaid by high value-added products. The application space of plasma technology is huge. Generally speaking, the development of plasma technology in the industrial revolution is relatively slow, but it can develop steadily.

Thereby improving the use efficiency of silicon wafers. The wet etching system is an etching method that peels off the etched object through a chemical reaction between a chemical etching solution. Most wet etching systems are isotropic etching that is difficult to control. Features: Strong adaptability, uniform surface, little damage to silicon wafers, suitable for almost all metals, glass, plastics and other materials. Disadvantages: The fidelity of the drawing is not ideal, and the drawing minimum line is difficult to grasp. Wet etching is a technique in which etching materials are immersed in an etching solution for etching. In short, it is the concept of chemical solution etching in middle school chemistry class. It is a pure chemical etching with excellent selectivity. It stops after etching the current film without destroying other materials below. film. Semiconductor wet etching systems are all isotropic etching, so for the etching of the oxide layer and the metal layer, the width of the horizontal etching is close to the vertical etching depth. In this way, the pattern on the upper photoresist and the pattern on the lower material will have a certain deviation, so that the work of pattern transfer and replication cannot be completed with high quality. Therefore, as the feature size decreases, in the process of pattern transfer Basically no longer used.
