PBN Electrostatic Chuck
The primary function of Semicorex PBN Electrostatic Chuck is to provide reliable wafer handling and temperature management in semiconductor processes.
Material Properties and Purpose
We are pleased to present the PBN Electrostatic Chuck, a cutting-edge solution for wafer handling at high temperatures, from Semicorex. This cutting-edge solution offers remarkable performance and dependability while meeting the demanding requirements of semiconductor processing.
Material Properties
Pyrolytic Boron Nitride (PBN), a high-purity ceramic material known for its exceptional qualities, particularly in high-temperature applications, is used to create the PBN Electrostatic Chuck for wafer handling processes.
Stability at High Temperatures
Our PBN Electrostatic Chuck is designed to work with wafers that are hotter than 1000°C. With metal impurities of fewer than 1 ppm, PBN is extremely pure, which contributes to its exceptional thermal stability. This guarantees that the Electrostatic Chuck will continue to function and retain its integrity even after extended exposure to high temperatures, making it perfect for demanding wafer handling processes.
Outstanding Resistance to Chemicals
PBN has outstanding resistance to corrosive conditions and is chemically stable. This characteristic is essential for preserving the chuck's functionality in reactive environments, guaranteeing durability and reliable operation in a range of semiconductor wafer handling applications. The material's excellent purity and chemical stability make it appropriate for ultra-high vacuum settings where contamination must be kept to a minimum.
Control and Thermal Uniformity
High-density, multizone heating components in the PBN Electrostatic Chuck offer remarkable thermal homogeneity. Wafers can be kept within extremely narrow temperature ranges thanks to this level of precision, which improves wafer handling processing conditions and guarantees high-quality results. The Electrostatic Chuck's multizone functionality allows it to manage even the most intricate control schemes, such as backside gas management and multi-zone chucking.
Shock Resistance and Structural Integrity
PBN is a thin, compact, completely dense polymer that has exceptional resistance to heat shock. The Electrostatic Chuck can tolerate abrupt temperature fluctuations thanks to its structural integrity; ramping speeds can approach 100°C/min. These characteristics improve throughput and operating efficiency and are essential for wafer handling processes that need rapid cycles of heat-up and cool-down.
Customization and Machinability
Because PBN is machinable, it may be formed into a wide range of shapes, providing flexibility and customisation to satisfy particular application requirements. The PBN Electrostatic Chuck is a flexible tool in semiconductor production because of its ability to be adjusted to meet a variety of wafer handling process needs.
Operation
Reliable wafer handling and temperature control in semiconductor wafer handling processes are the main purposes of the PBN Electrostatic Chuck.
Managing Wafers
Wafers are held firmly in place throughout wafer handling processing by our PBN Electrostatic Chuck, which ensures stability and exact placement even at elevated temperatures. Since even little variations might affect the quality of the final product, this feature is essential for guaranteeing precise and reliable results in semiconductor fabrication.
Control of Heat
The Electrostatic Chuck's multizone architecture and high-density heating components allow for accurate thermal management, guaranteeing that wafers stay within predetermined temperature ranges during the process. For wafer handling procedures where uniform heating is necessary to achieve the desired material properties, including chemical vapor deposition (CVD) and sputtering, this exact control is crucial.
Adaptability in Use
The PBN Electrostatic Chuck can be used for high-temperature heating tasks other than wafer handling. It works well as a heater for metal sources for evaporation, substrates in sputter and CVD equipment, and sample heating in electron microscopes. Its adaptability across a range of semiconductor processes is further demonstrated by its ability to be employed as a nozzle heater for gas heating.
Our dedication to quality and innovation at Semicorex motivates us to offer solutions like the PBN Electrostatic Chuck, which are made to satisfy the changing demands of the wafer handling in semiconductor sector. This Electrostatic Chuck is a dependable way to achieve accuracy and efficiency in high-temperature processing because of its sophisticated material properties and multipurpose use.
