Common Applications
Wafer Manufacturing Equipment
Wafer Manufacturing Equipment – Wafer front end (WFE) equipment creates the wafers which will be used in the semiconductor manufacturing process. These wafers are thin slices of a purified crystalline material, typically silicon extracted from silica sand, that serve as the foundation for the fabrication of semiconductor chips and integrated circuits. Once a silicon ingot has been refined, it is sliced into a wafer with diamond-edged saw blades, then smoothed and polished to a mirror-like surface before being thoroughly cleaned of any remaining particles. Completed wafers are then thoroughly tested using automated probes.
Products for Wafer Equipment
Stepper Motors
Stepper motors are commonly used in WFE (Wafer Fabrication Equipment) to control the movement of various components, such as wafer handling systems, robotic arms, and precision stages. The precise and repeatable motion of stepper motors allows for accurate positioning and control, which is crucial in the manufacturing of semiconductor wafers. These motors are also known for their high torque and reliability, which makes them ideal for use in harsh industrial environments. Additionally, stepper motors can be easily interfaced with control systems.
Encoders
Encoders are used to precisely measure the position, speed, and direction of the wafer in the machine's processing chamber. This information is essential for controlling the various mechanical and chemical processes that take place during each step of wafer fabrication. Encoders help ensure that the wafer is accurately positioned at each stage of the manufacturing process, resulting in high-quality, reliable wafers.
Linear Stages
Linear stages are commonly used in WFE machines to precisely move wafers through various processes in a linear motion with very high accuracy, which is crucial for achieving high-quality results in the semiconductor manufacturing process. Linear stages are typically equipped with advanced sensors and control systems that enable them to maintain precise positioning and velocity control, even at high speeds.
Wafer Probing Machines
Wafer Probing Machines – Wafers must be tested prior to being sent to die preparation. Wafer probers are automated tools which use a series of probes to test and measure the electrical properties of the wafer. During electrical testing, a set of stationary probes (aka a probe card) create electrical contact with a wafer that is held in place by a vacuum-mounted wafer chuck. The wafer prober is equipped with automatic pattern recognition optics that ensure precise alignment between the contact pads on the wafer and the probe tips. Once a die or array of dies have completed a test, the prober moves the wafer to the next die or array to begin the next test.
Products for Wafer Probers
BLDC Motors
BLDC motors are commonly used in wafer probers due to their efficiency, reliability, precise control, and high torque capabilities. These motors precisely position the wafer under the probe needles, ensuring accurate testing.
Linear Guides
Linear guides are used in wafer probers to provide precise, smooth movement of the probe card assembly across the wafer. The rail provides a stable base for the carriage to move along, while the carriage holds the probe card assembly and moves it across the wafer. Linear guides ensure that the probe card assembly maintains a consistent and controlled distance from the wafer surface, which is critical for accurate testing of the semiconductor devices on the wafer. The guides also help prevent any unwanted movements or vibrations that could cause damage to the wafer or affect the accuracy of the test results.
PLCs
PLCs are used in wafer probers to control the prober's various mechanical and electrical components. These controllers execute a series of pre-programmed instructions that manage the movement of the prober's probes and wafers, as well as the collection and analysis of data. PLCs are ideal for wafer probers because they are reliable, flexible, and can be easily programmed to suit the specific needs of the testing process. They can also be easily integrated with other computer systems, such as data acquisition and analysis software, to provide a comprehensive testing solution. PLCs can also be used to monitor and regulate the prober's environmental conditions, such as temperature and humidity, to ensure optimal testing conditions which helps to ensure the accuracy and consistency of test results.
