TFT Chemicals offers a high-quality stripping solution, primarily composed of organic solvents that may include organic acids, organic bases, and surfactants. These carefully selected components work together to facilitate chemical reactions and physical interactions with the target material, effectively separating it from the substrate. As a leading factory and supplier in China, we are committed to providing efficient and reliable solutions for your stripping needs.
In the manufacturing process of integrated circuits and display panels, "stripper" usually refers to the developer used to remove the unexposed parts of the photoresist. Its usage steps generally include:
Exposure
During the manufacturing process, photoresist is coated on the surface of the silicon wafer. The adhesive layer is then exposed to light with a design pattern. Through the photolithography process, the pattern is transferred to the photoresist.
Development
The unexposed parts need to be removed. In this step, a developer (stripper) is used to remove the photoresist from unexposed areas to create the desired pattern.
Cleaning
Clean the silicon wafer and remove any developer residue that may remain on the surface. During the display panel manufacturing process, similar developers may also be used to remove certain materials or compounds to form specific patterns or structures of the display panel. In all cases, use of developer requires compliance with the manufacturer's instructions and safety recommendations to ensure the safety of workers and the correct use of production equipment.
In the chip manufacturing process, Stripper usually refers to a photoresist stripper, which is used to remove photoresist. Photoresist is a key material used for pattern transfer in chip manufacturing. In the photolithography process, photoresist is coated on the surface of the chip, and then the required pattern is formed through steps such as exposure and development. However, once the pattern transfer is complete, the remaining photoresist on the chip surface needs to be removed in order to proceed with the next process step, such as etching or deposition. At this time, you need to use Stripper to remove the photoresist. Stripper is usually a chemical solution that can quickly and effectively dissolve and remove photoresist without damaging the chip surface. This process is critical to ensuring the accuracy and quality of chip manufacturing. After the photoresist is removed, the chip surface becomes clean, providing a clean surface for subsequent process steps.
Frequently Asked Questions (FAQ)
What is a stripper in display panel and chip manufacturing?
In these manufacturing processes, a stripper (or photoresist stripper) is a specialized chemical solution used to dissolve and remove photoresist from the substrate surface after pattern transfer (such as etching or deposition) is complete.
What are the primary applications and chemical components listed for TFT-LCD?
For TFT-LCD applications, the primary classification is Stripper. Key products include Dimethyl Sulfoxide (DMSO) and Monoethanolamine (MEA), both maintaining a high purity level of less than 100ppb.
What are the three main steps in using a developer/stripper?
The process involves three main steps:
1. Exposure (transferring the pattern to the photoresist using light),
2. Development (removing unexposed areas of photoresist), and
3. Cleaning (removing any chemical residues from the surface).
Why is it necessary to remove the photoresist after pattern transfer?
Once the pattern transfer is complete, the remaining photoresist is no longer needed. It must be cleanly removed to expose the surface for subsequent manufacturing steps, such as etching or material deposition.
How does the stripper remove photoresist without damaging the chip?
Strippers are specifically formulated chemical solutions designed to selectively dissolve and strip away the photoresist layer quickly and effectively, without reacting with or damaging the underlying silicon wafer or chip surface.
