SCHMID Group Takes Next Step Towards Advanced Packaging for Integrated Circuits with Glass Cores

 

One current market trend is the introduction of glass cores in advanced packaging, which will take major market share from the traditional organic core as well as the traditional silicon-based applications. The idea of moving to glass core has started a new diversification in the supply chain enhancing the resilience and flexibility of the semiconductor industry.

 

The main beneficiaries today are the fast-growing AI and data center sectors but soon after, we also see glass cores expanding into any high-speed computing application, for example automotive applications.

 

 

 

Based on decades of experience in glass processing and substrate manufacturing, sourcing from our 3000 sqm unique world-class laboratory located at our headquarters in Freudenstadt, Germany – SCHMID has developed the capability to produce and metallize glass cores, as well as the redistribution layers on both sides. The SCHMID R&D center has the capability to add this full build up “fan out” layer on top based on the standard Semi Additive process (SAP), or with the most advance, SCHMID invented, ET (Embedded Traces) process. This gives customers and partners of SCHMID the unique opportunity to develop and sample full format packages substrates up to 24*24” with glass core thickness ranging from 200µm to 1.1mm comprising high aspect ratio through holes.

 

All the machines used are based on high volume manufacturing platforms and can be quickly expand to mass volume production. The installed pilot line is also offered to key customers to expand their R&D capability and interlink it with SCHMID`s own R&D activities to increase speed further.

 

 

SCHMID has provided glass processing solutions to the PV, anti-glare and display industry for many years. Glass cleaning and etching of ultra-thin glasses including FOUP based automation is within the SCHMID standard machine portfolio. High aspect ratio through glass via formation requires a wide knowledge base for using the right laser and etching parameters for the different types of glasses as well as a profound electro plating experience for a void free through hole copper filling and planarization. All of this has been developed by SCHMID over the last years and will be provided along with the lab solution.
