Chemical Vapor Deposition (CVD)
Chemical Vapor Deposition (CVD) is a process used in semiconductor manufacturing to deposit thin films of material onto a substrate. In CVD, gaseous precursors react chemically on the surface of a heated substrate, forming a solid material layer. The reaction often occurs at high temperatures and in a controlled environment to ensure uniformity and purity. CVD is essential for creating layers like silicon dioxide, silicon nitride, or various metals, which are crucial for building microelectronics. It allows for precise control of film thickness, composition, and properties, making it ideal for producing semiconductors with high-performance and durability. Motors play a key role in Chemical Vapor Deposition (CVD) equipment by enabling precise control and movement of various components during the deposition process. Typically, motors are used to rotate the substrate, operate valves and pumps, and control heating elements. These motor-driven functions enhance precision and reliability in achieving high-quality thin films.

Wafer Transfer Arm Drive
The Wafer Transfer Arm Drive plays a crucial role during the etching process by precisely moving and positioning wafers between different processing stations within the etching equipment. It ensures the safe handling of delicate semiconductor wafers, minimizing the risk of contamination or damage. Key functions include precise placement, automated handling, and cleanroom compatibility. Because of the need for such precision, lower quality motors with traditional encoders are not an appropriate solution. In contrast, our hybrid motors with absolute encoders are absolutely essential within the critical semiconductor wafer etching process.
