Things You Probably Didn't Know About Precision Motion Control & Wafer Front End Process?
What is Precision Motion Control?
Precision motion control is treated as a leader in motion control devices and advanced motors, proffering a wide array of hybrid steppers, brushless motors, motor-blowers, brushless direct-current servo motors, customized rotary & linear motion solutions, lead screw assemblies to operate and maintain the myriad of industrial and engineered control applications.
It is a system that is fabricated with three components that are controller, drive, and motor. It fulfills the needs of automation and aerospace industries with the utmost ease. But nowadays, the development of precision motion control systems is used for electronic components and ultra-precision semiconductor manufacturing.
What is the Wafer Front End Process?
Wafer front end or wafer fabrication (front-end) is an identical integrated circuit known as a 'die' built on each wafer in a multi-step phase. Each process introduces new layers to the wafer or sometimes changes the existing ones. With the help of layers, the individual electronic circuits form the elements with different scenarios.
Know the basic types of Precision Motion Control?
There are various types of precision motion control systems available, but we will discuss the custom-fits.
Precision Motion Control Linear Stage
The precision motion control linear stage is used in laboratories to handle everyday machine tasks. It features real-time force sensing, repeatable actions & contactless read-head design. Other than that, it comes with a simple structure that you can operate in silent mode. There is no requirement to adjust the PID parameters before gaining the super-fast performance.
33LR Integrated X, Y, Θ Precision Motion Control Stage
33LR integration X, Y, Θ is one of the precision motion control stages offering the automatic machine service to serve the need of applications by using digital sensing methods. It comes with the non-contacting read-head design that is mainly provided to eliminate the hysteresis. It works with 360-degree continuous moments without producing any noise.
Precision Motion Control Rotary Stage Motor
The
precision motorized rotary stage delivers the long-lasting operations with high
performance. You can use it individually or combined with the X-Y-Z-Θ stage,
X-Y-Θ systems. It gives ease to link the backlash with the constant movements.
It also has many mechanical controls that you can use to acquire the power-pack
performance without worrying about excessive heat.
What are the Steps Used in Front End Wafer Fabrication?
Photomasking
A photomask is a tool utilized for the production of components - displays, MEMS, Semiconductors. With the help of this tool, the manufacturer transfers the pattern of baseplates. In the front-end process, it may be used to maintain the shape of these elements.
Etching
The next step in the fabrication for die is to remove the thin film material using etching operations. Two types of methods used for the etch process - Wet or Dry. Wet etching uses the soluble compounds & dry one uses the gaseous compounds while implementing any tasks.
Diffusion
Introduces the dopants within the material or may be employed for the growth of a thin oxide layer onto the wafer. The implantation of wafers needs a high temperature of up to 1200-degree Celsius in the stage of diffusion.
Back-lap
It is also the step of front-end wafer fabrication in which the thickness of wafers is reduced for microcontroller chips. Sometimes, the system may deposit the thin gold layer on the back of the wafer.
