https://www.by-micro.com/products/koh-develope , r.html Description The main components of KOH developer, KOH, surfactant and metal protective agent, can dissolve the uncured part of the photoresist and develop the part exposed to ultraviolet light, with faster development speed and higher selectivity. The optimal pH value for development is between 12-13. In addition, the developer also contains some auxiliary agents such as surfactants and antioxidants, which can also improve the performance of the developer and improve the development effect and stability. However, potassium hydroxide series developers contain mobile ion contamination (MIC), which is not suitable for high-performance display panels and integrated circuit industries that are very sensitive to pollution. Features 1. ​Strong alkalinity: KOH completely ionizes in water to generate K+ and OH− ions, which are highly alkaline and can react quickly with acidic substances or certain organic materials. ​2. High development efficiency: KOH developer has a high development rate for certain photoresists (such as positive photoresists) and can quickly dissolve unexposed parts. 3. ​Low cost: KOH is a common inorganic base with a relatively low price, so it has advantages in certain cost-sensitive applications. 4. ​Metal ion residues: KOH developer contains potassium ions (K+), which may remain on the wafer or substrate and have an adverse effect on the performance of semiconductor devices. Application ​1. Semiconductor manufacturing: In the early photolithography process, KOH developer was widely used for the development of positive photoresist, but as the purity and performance requirements of semiconductor processes increased, KOH was gradually replaced by metal-free developers such as TMAH. ​2. Printed circuit boards (PCBs): In PCB manufacturing, KOH developer is used to remove unexposed photoresist and form circuit patterns. ​3. Micro-electromechanical systems (MEMS): KOH developer is also used in MEMS processes, such as anisotropic etching of silicon wafers.

https://www.by-micro.com/products/tmah-develop , er.html TMAH Developer TMAH developer is a commonly used developer, and its main component is tetramethylammonium hydroxide. TMAH is an organic base with strong alkalinity, which can cause the developer to deposit on the silver salt grains to form a black silver image. Description TMAH Developer is a commonly used developer, and its main component is tetramethylammonium hydroxide. TMAH is an organic base with strong alkalinity, which can cause the developer to deposit on the silver salt grains to form a black silver image. On the other hand, it has its unique characteristics, that is, it will not leave metal ions during use, and can be decomposed into trimethylamine gas and methanol gas without leaving any traces after heating, and can be widely used in the modern electronics industry. In addition to TMAH, our company will also add some independently developed additives to adjust the speed and effect of the developer. In order to avoid the collapse of the photoresist lines, a small amount of surfactant can also be added to the TMAH aqueous solution. TMAH Developer (Tetramethylammonium Hydroxide) is a critical solution in the semiconductor manufacturing process, specifically for photolithography applications. It offers precise and consistent development of positive photoresists, enabling high-resolution patterning required in advanced microelectronics. Our TMAH Developer is designed to meet the rigorous demands of the industry, with customizable options to support diverse manufacturing and R&D needs. TMAH has strong alkalinity Tetramethylammonium hydroxide (TMAH) is a strong alkalinity organic base with a molecular formula of (CH3​)4​NOH. Its strong alkalinity is mainly reflected in its pH value greater than 13. It can quickly absorb carbon dioxide in the air to form carbonates, and its alkalinity is stronger than common inorganic bases such as sodium hydroxide (NaOH) and potassium hydroxide (KOH). The strong alkalinity of TMAH comes from the quaternary ammonium cations (CH3​)4​N+ and hydroxide ions OH− in its molecular structure. This structure makes it completely ionized in water and exhibits strong alkalinity.

https://www.by-micro.com/productstags/high-pur , ity-solvents.html High-purity solvents in semiconductor materials refer to chemical solvents that have undergone rigorous purification and have extremely high purity. These solvents are critical in the semiconductor manufacturing process because they can effectively avoid impurities and contamination, thereby ensuring the performance and reliability of electronic devices. Characteristics of high-purity solvents 1. Extremely high purity: The purity of high-purity solvents is usually more than 99.9%, and some even reach 99.999%. This high purity is achieved through advanced technologies such as multiple distillations and filtrations to remove any impurities that may affect the semiconductor manufacturing process. 2. Low impurity content: The content of metals and other impurities in these solvents is extremely low, usually at the level of one billionth or one trillionth. This is critical to avoiding defects in key steps such as wafer cleaning, etching, deposition, and photolithography. Application areas Photolithography resist production: High-purity solvents are often used in the preparation of photolithography resists, which is an important step in creating complex patterns in semiconductor manufacturing. Wet electronic chemicals: These solvents are also key ingredients in processes such as wet etching, cleaning, and development, ensuring the accuracy and stability of each manufacturing link. Cooling systems: Certain high-purity solvents such as isobutane are also used as coolants for electronic equipment, favored for their good thermal conductivity and environmental friendliness.

https://www.by-micro.com/productstags/photores , ist-ancillaries.html Photoresist ancillaries refer to a range of chemicals and materials used in conjunction with photoresists during the lithography process in semiconductor manufacturing. These ancillaries play crucial roles in enhancing the performance and efficiency of the lithographic techniques employed to create intricate patterns on substrates. Types of Photoresist Ancillaries 1. Developers: Developers are used to create patterns by exploiting the differences in solubility between exposed and unexposed areas of the photoresist. This process is essential for transferring the desired patterns onto the substrate. 2. Stripping Solutions: These solutions are utilized to remove photoresist after etching processes, as well as to eliminate impurities that may arise during manufacturing. They ensure that the substrate is clean for subsequent processing steps. 3. Thinners: Thinners are employed in various processes, such as edge rinsing and back rinsing after photoresist application, to ensure even coating and optimal performance. Market Overview The global market for photoresist ancillaries is projected to grow significantly, driven by advancements in semiconductor technology and an increasing demand for consumer electronics. The market is expected to expand from USD 4.1 billion in 2023 to USD 5.3 billion by 2028, with a compound annual growth rate (CAGR) of 5.1% during this period. The Asia-Pacific region is anticipated to dominate this market due to its robust semiconductor manufacturing capabilities and rising demand for advanced electronics. The photoresist ancillaries are essential components in the lithography process, enhancing the effectiveness of photoresists and contributing to the production of high-quality semiconductor devices.
