Intel has filed a patent detailing the integration of MicroLEDs directly into a CPU package. The technology involves embedding a semiconductor die within a glass substrate, which serves as the foundation for the LED array. Power and signals are delivered to the die through through-glass vias, while silicon nitride layers are used to attach the components to the package substrate.
The patent suggests multiple potential applications for the embedded LEDs, ranging from aesthetic lighting effects to functional readouts that indicate processor activity. The design allows for the use of different LED colors. While the current documentation shows a single integrated circuit, Intel notes that future implementations could feature multiple arrays of MicroLEDs across one or more packages.
Intel has been developing glass substrate technology for more than three years, citing a 10-fold improvement in interconnect density compared to traditional organic substrates. The company filed this specific patent over four years ago. As with any patent filing, there is no guarantee that this technology will appear in future commercial products.
