Evolving Requirements in Semiconductor Manufacturing

The semiconductor production business is witnessing tremendous technical breakthroughs that significantly challenge the requirements for motor technology. The precision and purity required for current semiconductor production are setting new standards in the design and functionality of specialist motors.

Trends in Semiconductor Manufacturing Influencing Motor Technology

The push toward increasingly smaller semiconductor structures, as observed in 5 nm and 3 nm processes, requires a level of precision in motor operations never seen before. Therefore, to accommodate this trend, we need motors that can operate with extremely small movements and possess positioning capabilities. Additionally, the trend toward increasingly automated and densely packed manufacturing lines is driving the demand for motors that can fit into small spaces without compromising their performance.

Key trends include:

Miniaturization: In the process of miniaturization, the necessity for very accurate motor motion increases as the size of the components decreases. In order to attain the required level of accuracy, sophisticated feedback and control systems are required.

Increased Automation: As more stages of semiconductor manufacture become automated, the demand for motors capable of maintaining constant performance over extended periods of time and under demanding conditions grows.

Increasing Demand for Precision and Cleanliness

Semiconductor environments must exhibit a high level of cleanliness, often tested at class 10 or higher cleanroom standards, to prevent contamination that could result in defects. Motors in these environments require not only a high level of precision, but also a design that minimizes particle generation. This has consequently led to the development of motors with specialized enclosures and materials that reduce particulate shedding during operation.

Critical considerations include:

Non-Particulate Generating Materials: It is of the utmost importance to make use of materials and lubricants that do not eventually break down into particles. Examples of such materials include advanced ceramics and vacuum-rated greases. Due to the extraordinarily high precision and cleanliness standards that are required in the fabrication of semiconductors, motor components are required to make use of specialist materials in order to eradicate the possibility of contamination. This discussion illustrates the specific use of non-particulate-producing materials in motors.

• Advanced Ceramics:
• Bearings and Shafts: Motors frequently use ceramics for bearings and shafts due to their hard and smooth surfaces. Ceramics reduce friction and wear, thereby greatly reducing the amount of particulate produced. In cleanroom conditions, where even minute particles might damage production processes, ceramic bearings are extremely beneficial because of their ability to prevent contamination.
• Insulation and Structural Components: Motor designs utilize ceramic materials for insulation and structural component construction. Because of their exceptional thermal stability and resilience to thermal shock, they are ideal for preserving performance in the regulated settings that are characteristic of semiconductor production.
• Vacuum-Rated Greases:
• Lubrication of Moving Parts: To perform without any clogging or friction, motors used in semiconductor production frequently require lubrication. However, when subjected to vacuum conditions, ordinary lubricants have the potential to evaporate or outgas, which can result in contamination. The purpose of vacuum-rated greases is to operate under low-pressure conditions without deteriorating or producing toxic vapors that could cause particulate pollution. This is due to the design of vacuum-rated greases.
• Magnetic Materials:
• Rotor and Stator Components: Both the rotor and the stator use high-purity magnetic materials to ensure the motor operates with minimal mechanical resistance and electromagnetic noise. We do this to prevent the occurrence of micro-vibrations and the subsequent formation of particles.

Enhanced Sealing Techniques: We outfit motors with low-friction or non-contact-type seals that meet strict cleanliness criteria necessary in semiconductor manufacture. This is done in order to further prevent such contamination from occurring.
