All about Wafer Pre Aligner and Wafer Automation

1. All about Wafer Pre Aligner & Wafer Automation www.kensingtonlabs.com

2. Wafer Pre-Aligners Wafer pre-aligner plays a vital role in wafer manufacturing. It positions wafers accurately before they get transferred onto the exposure platform. The positioning accuracy significantly affects the wafer's exposure accuracy and the whole manufacture system's work efficiency. The paper makes an overview of wafer pre-aligner from the following features: mechanical structure, machine vision, working principle, and the algorithm on the detection of the wafer edge.

3. Wafer Automation The wafer automation's major role is to maximize the process control by keeping the inside elements safe from the outside elements such as dust. The silicon wafers or chips of electronic products trap the dust very easily. Dust can block the path and can reduce the functioning of the system. Here comes wafer automation to the rescue. It helps to eliminate these problems and provide the correct amount of chemicals in microchips to maintain inner hygiene.

4. Advantages • Cost-Effective When we compare the manual equipment for semiconductors, we see that the mechanized wafer fabrication systems are highly cost-effective. There is a real-time functioning benefit, and the chemicals are at the optimum level needed for the machine to increase the production line's performance. • Optical Sensing Abilities  The fully-automatic edge grip system is responsible for monitoring and performs the required functions. Maintaining the right position of the Integrated circuits is crucial, and if they are misplaced, one cannot achieve better results. By using sensors, the wafer handlers can provide the repeatability feature and increase the operating life. • Seamless Data Logging It is possible to get the amenities of data logging with wafer handlers. It requires an Ethernet connection for achieving the filling service, easy-loading, and tracking the processed variables. 

5. Stage Repair Services Stage repair services are powerful automatic motion controller products that can increase robots' lives without any difficulty. When it comes to reducing capital investment, these devices especially take care of noise and heat. Many stage repair systems are there in the market, but the most commonly used are Gantry precision control & contract manufacturing equipment. It offers complete tailor-fit solutions that deliver a high range of speed.

6. Advantages • From commercial to technical aspects, everything is achieved entirely by stage and repair contract manufacturing services. • When the product is bought from a reliable and trustworthy manufacturer, you get a warranty on the product, and repair is done for free in that period. It saves you from the extra cost. • Velocity and travel range like requirements can be fulfilled, and it presents the ultra-smooth operations without creating backlash linking.

7. Wafer Handling Front End System The wafer handling front end system is a single IC that is great for placing wafers by step-by-step methods. The first step involves fixing a new layer of the identical IC or die on the wafer. After that, it assists in making further modifications in the previous-used hardware design. Also, the front-end wafer handler implements the easy installation of a sturdy wrist. It incorporates the many individual devices in the semiconductor such as capacitors, transistors, resistors, etc.

8. Benefits When making the simple fabrication strategy, the wafer handling front end system provides a wide range of advantages. Some of them are mentioned below: • It comes in many types of robots, such as single wafer robots, multi-link SCARA wafer robots. These robots play a vital role by using mechanical and chemical forces to make the surface smooth and clean.  • With wafer handling front-end effectors, there are no electric current leakage chances because it employs the box-isolation technique, which helps keep the device components secure and in excellent working condition.  • It makes use of the drain modules, gate modules for circulating the proper flow of content in the circuits.
