What is Wafer Coring?



Wafer Dicing Service

Wafer coring is a process used in semiconductor and device fabrication. It is a direct-write lithography technique that uses small, square chips of materials to create patterns on semiconductor substrates. Coring provides the foundation for several types of circuitry, including capacitors and transistors. Wafer coring has come a long way since its inception in the late 1960s. Today’s systems are able to produce more accurate and detailed patterns with less waste. This blog post will explore the basics of wafer coring and how it can be used to create intricate circuit boards. By the end, you will have a much better understanding of this essential manufacturing process.

What is wafer coring?

Wafer coring is a process that removes surface material from a wafer. This can be important for several reasons, including improving the quality of microchips, and understanding circuit behaviour, and manufacturing processes. Wafer coring can be done with both manual and automated methods.

How does wafer coring help with PCB removal?

Coring is a process that helps with PCB removal. Wafer coring is a method of removing substrates from a wafer by using a small-diameter cylindrical tool to create deep channels in the substrate. This allows the substrate to be easily peeled away from the wafer.

What are the benefits of wafer coring?

Coring is a process used to remove a single layer of silicon wafers from a semiconductor wafer. The wafer is first diced into small pieces and then spread out on a surface. A small hole is then drilled through the top of the wafer, and the coring tool is inserted into the hole. The tool begins to rotate around the circumference of the hole, removing the silicon wafers as it goes.

The advantage of this process is that it allows for a better understanding of how each individual transistor works. By coring off each transistor, engineers can map out its circuit more accurately and know where defects are located. Additionally, cored chips can be used in devices that require high levels of miniaturization, such as electronic components or microchips.

How do I perform wafer coring?

Coring is the process of removing a complete chip from a wafer. It is used in semiconductor manufacturing to produce chips with smaller dimensions, which are beneficial for faster and more efficient circuitry. The process begins by etching a pattern into the wafer using an ultrafine-pointed tool called a coring knife. The tool’s sharp edge then pierces through the wafer, creating dozens of small holes. These holes can be as small as 100 nanometers across, meaning that they can see through most substances. After the coring knife has created the desired pattern, the chip is pulled out of the wafer using suction and immersion in a cleaning solution.


What is wafer coring? Wafer coring is a computer-aided manufacturing process that uses lasers to create precision holes in semiconductor chips and other substrates. By creating these tiny holes, manufacturers can better control the flow of materials and electrical signals through their products.
