Applied Producer Avila 2 PECVD 

In advanced packaging, through-silicon vias (TSVs) are a foundational enabler, especially in 2.5D interposers and many 3D integration schemes. As memory manufacturers stack more DRAM dies in high-bandwidth memory (HBM) devices, TSVs provide the vertical interconnects needed to deliver higher bandwidth, faster performance and lower power consumption. But HBM scaling is becoming more challenging as ultra-thin wafers, complex film stacks and high-density vias demand tighter control of wafer warpage, stress evolution and thermal budgets during via reveal. Excessive bow or non-uniform warpage can narrow process windows and lead to yield loss.

The Applied Producer^™ Avila^™ 2 system is a next-generation PECVD system designed to address these challenges with advanced thermal management and wafer-bow control for TSV via reveal applications. The system delivers highly uniform temperature distribution for processing below 200°C, enabling customers to meet tight thermal budgets while maintaining process performance. A key advantage is its ability to provide higher bow compensation, helping achieve tighter and more uniform chip warpage distribution. This enables tighter process control, improved yield and support for increasingly complex integration schemes. Avila 2 also enhances productivity and supports multiple wafer support substrates, including silicon and glass.

Within Applied Materials’ advanced packaging portfolio, Avila 2 works alongside Insepra^™ in hybrid bonding flows by enabling the dielectric films needed for fine-pitch copper bonding. Together, these systems help customers scale next-generation HBM and 3D integration with the film performance, thermal control and process capability required for more demanding device architectures.
