Enabling Next-Generation Advanced Packaging and HBM Manufacturing Through Photonic Debonding

The rapid growth of artificial intelligence and high-performance computing is driving increasingly complex semiconductor packaging architectures. High Bandwidth Memory (HBM), chiplets, heterogeneous integration, hybrid bonding, and ultra-thin wafers require temporary bonding and debonding technologies capable of handling fragile substrates while maintaining high throughput, low thermal budgets, and broad material compatibility. Conventional thermal, mechanical, and laser-based debonding approaches face increasing challenges as wafers become thinner, package structures become more complex, and manufacturing transitions toward larger substrates.

PulseForge offers industry’s leading  Photonic Debonding, a broadband, high-intensity pulsed-light technology enabling rapid, low-force separation of temporarily bonded semiconductor substrates. Unlike conventional laser debonding based on point-by-point scanning, photonic debonding  illuminates large areas using microsecond-duration light pulses. Energy is absorbed by a light-absorbing layer (LAL) at the carrier interface, enabling localized release while no thermal exposure of the device wafer.

PulseForge has demonstrated Photonic Debonding across multiple temporary bonding adhesives, carrier materials, wafer architectures, and semiconductor substrates, providing manufacturers flexibility in temporary bonding material selection. The technology is particularly suited for highly warped, ultra-thin (<10 um), and mechanically fragile wafers where minimizing debonding force and thermal exposure is critical.

Recent developments include spin-coatable light-absorbing layers (SLALs) and chemically etch resistant reusable LAL carriers, providing pathways to simplify process flows and reduce consumable costs. Large-area photonic illumination also provides inherent scalability from wafer to panel-level processing. PulseForge recently demonstrated DRAM wafers thinned down to below 10 um with a Korean memory manufacturer.

Fully automated, semiconductor-compatible Photonic Debonding platforms are being developed for high-volume manufacturing. This presentation will highlight recent technical results and demonstrate how microsecond processing, low thermal exposure, near-zero-force separation, material flexibility, and wafer-to-panel scalability can address emerging debonding challenges for next-generation HBM, hybrid bonding, chiplet, and heterogeneous integration.
