Electrostatic Chuck E-Chuck

Semicorex Electrostatic Chuck E-Chuck operates on the principles of electrostatic attraction, offering reliable and precise wafer retention without the need for mechanical clamps or vacuum suction, especially used in etching, ion impl-

antation, PVD, CVD, etc semiconductor processing. Its customizable dimensions make it adaptable to a wide range of applications, making it an ideal choice for companies seeking flexibility and efficiency in semiconductor fabrication processes.

The fundamental technology behind the J-R type Electrostatic Chuck E-Chuck is its ability to generate an electrostatic force between the wafer and the chuck's surface. This force is created by applying a high voltage to electrodes embedded within the chuck, which induces charges on both the wafer and the chuck, thereby creating a strong electrostatic bond. This mechanism not only holds the wafer in place securely but also minimizes the physical contact between the wafer and the chuck, reducing potential contamination or mechanical stress that could damage sensitive semiconductor materials.

Semicorex can produce the customized products, from 200 mm to 300 mm or even larger, depending on the requirements from the customers. By offering these customizable options, the J-R type ESC provides maximum flexibility for a range of semiconductor processes, including plasma etching, chemical vapor deposition (CVD), physical vapor deposition (PVD), and ion implantation.

In terms of materials, the Electrostatic Chuck E-Chuck is made from high-quality ceramic materials, such as alumina (Al2O3) or aluminum nitride (AlN), which are known for their excellent dielectric properties, mechanical strength, and thermal stability. These ceramics provide the chuck with the necessary durability to withstand the harsh conditions of semiconductor manufacturing, such as high temperatures, corrosive environments, and plasma exposure. Additionally, the ceramic surface is polished to a high degree of smoothness to ensure uniform contact with the wafer, enhancing the electrostatic force and improving overall process performance.

The Electrostatic Chuck E-Chuck is also designed to handle the thermal challenges commonly encountered in semiconductor fabrication. Temperature management is critical during processes such as etching or deposition, where the wafer’s temperature can fluctuate rapidly. The ceramic materials used in the chuck provide excellent thermal conductivity, helping to dissipate heat efficiently and maintain a stable wafer temperature.

The Electrostatic Chuck E-Chuck is designed with an emphasis on minimizing particle contamination, which is critical in semiconductor manufacturing where even microscopic particles can lead to defects in the final product. The smooth ceramic surface of the chuck reduces the likelihood of particle adhesion, and the reduced physical contact between the wafer and the chuck, thanks to the electrostatic holding mechanism, further lowers the risk of contamination. Some models of the J-R type ESC also incorporate advanced surface coatings or treatments that repel particles and resist corrosion, enhancing the chuck’s longevity and reliability in cleanroom environments.

In summary, the J-R type Electrostatic Chuck E-Chuck is a versatile and reliable wafer-holding solution that offers exceptional performance across a wide range of semiconductor manufacturing processes. Its customizable design, advanced electrostatic holding technology, and robust material properties make it an ideal choice for companies seeking to optimize wafer handling while maintaining the highest standards of cleanliness and precision. Whether used in plasma etching, deposition, or ion implantation, the J-R type ESC provides the flexibility, durability, and efficiency required to meet the demanding needs of today’s semiconductor industry. With its ability to operate in both Coulomb and Johnsen-Rahbek modes, handle high temperatures, and resist particle contamination, the J-R type ESC stands as a critical component in the pursuit of higher yields and improved process outcomes.
