Wafer and semiconductor manufacturing utilize automation throughout the entire process, from coating and etching wafers to photoresist stripping and machine polishing. These machines utilize various DC motors like hybrid stepper motors, BLDC motors, Slotless BLDC motors, and more. Motors often operate in extreme environments such as exposure to liquids, corrosive chemicals, or heated environments above the rated operating range of a standard motor. Many of these processes also occur in cleanroom environments where outgassing needs to be avoided at all costs.

  • IP Rated Motors For Wet Processing
  • Temperature Resistant Motors for Heated Environments
  • ISO9001 Certified

Lin Engineering Designs, Engineers, and Manufacturers DC motors. We have over 30 years of experience supplying motors to many of the top semiconductor system manufacturers worldwide. We’ve developed standard and specialized motors that solve some of the most challenging problems engineers face designing semiconductor manufacturing equipment.


Everything starts with our facility in Morgan Hill, California which is conveniently located in the heart of Silicon Valley. Not only do we have a full Engineering staff, there is also a local Quality team, Applications, Sales, Customer Service, and so much more. The crown jewel of it all? A California-based manufacturing facility that proudly makes motors in the USA.  For added support, we have a nationwide team of Applications Engineers and Account Managers that can provide you with the benefits of localized support.

Common Applications

Specialty Motors

Hot/Cold Environment
Card image

Spin track tools used for coating wafers are often heated to temperatures above 50 degrees Celsius, which is beyond the range of a standard motor. Our Hot/Cold motors are specifically designed to withstand extreme environmental temperature ranges.  

Ingress Protection (IP)

Wet Chemical stations for cleaning, etching, and more use strong chemicals and liquids. In these environments, an Ingress Protected motor is required. Our IP65 & IPx7 motors are water-resistant and can withstand jets of water sprayed from all directions.  

Vacuum Grade

Vacuum grade BLDC or Hybrid Stepper Motors are often a necessity during the semiconductor manufacturing process when outgassing needs to be minimized. Outgassing occurs when gasses and particles that are trapped inside paints, coatings, and greases, are released into the environment and introduce unwanted contaminants. Vacuum-rated stepper motors are designed using low-outgassing materials.

These motors are designed and manufactured to operate in unique environments for specific applications. Vacuum-rated motors, for example, are necessary for environments where out-gassing needs to be minimized such as vacuum chambers, space applications, and clean room environments. IP (Ingress Protection) rated motors are perfect for applications exposed to humidity, water, oil, and other various debris. We also carry motors that are specifically designed to operate in extreme hot and cold temperatures.
