CGD is the first to launch an independent GaN chip two-dimensional barcode, which can be read by a commercial code reader to identify the IC manufacturing location on the wafer
Cambridge GaN Devices (CGD) is an environmentally friendly semiconductor company that has developed a series of high-energy efficient GaN power devices and is committed to creating more environmentally friendly electronic devices. CGD once again demonstrated the company's innovative determination through leading industry initiatives: integrating a separate two-dimensional barcode on GaN ICs, which can be read through standard commercial code readers. This not only enables CGD to scan packaged devices and identify circuits and batches, but also accurately understand the manufacturing location of each chip on the wafer. This is of great significance for providing important data on process robustness and reliability.
Zahid Ansari | Vice President of Operations, CGD
We have collaborated with the packaging team to integrate a separate two-dimensional barcode, allowing us to have complete control over the entire process and the ability to solve any reliability issues. For example, we know that the yield at the edge of a wafer is the lowest, and now we can see how the position on the wafer affects device performance. This information can be fed back to the OEM factory to achieve continuous improvement of the manufacturing process.
The ability to immediately identify devices using inexpensive commercial code readers also has a significant impact on accelerating anti-counterfeiting measures, which will attract great interest from companies in the field of high reliability.
Giorgia Longobardi | CEO of CGD
Although we have a large amount of data to prove ICeGaN ™ The robustness and reliability of HEMT, but compared to traditional silicon used in power electronics applications, GaN is still a relatively new technology. By integrating two-dimensional barcodes, we can provide ultra fast feedback to the manufacturing supply chain, which helps consolidate our relationships and expand scale to achieve mass production
