Semiconductor Manufacturing Challenges
As device geometries shrink and packaging complexity increases, semiconductor manufacturers face unprecedented precision requirements. Our laser micromachining solutions deliver the accuracy, throughput, and yield your advanced processes demand.
Shrinking Feature Sizes
Advanced nodes require micron precision for microvias, TSVs, and die singulation. Mechanical methods can't achieve the tolerances needed for advanced nodes.
Advanced Packaging Complexity
2.5D/3D integration, fan-out wafer-level packaging, and heterogeneous integration demand precise microvia drilling and RDL patterning with tight registration.
Yield & Throughput Pressure
High-volume production requires consistent process control, minimal kerf loss, and high throughput without compromising die strength or edge quality.
Thermal Management
Power devices and RF applications require precise processing of SiC and GaN with minimal heat-affected zones to preserve electrical characteristics.
Material Diversity
From silicon and compound semiconductors to glass interposers and ceramic substrates, each material requires optimized laser parameters for clean processing.

Advanced Packaging Process Integration
Enabling Next-Gen AI Chip Production
How we helped a leading AI semiconductor company overcome advanced packaging challenges to deliver 7nm chips with 2.5D integration.
The Challenge
A leading AI chip designer faced critical yield issues in their 7nm GPU advanced packaging process. Thermal stress during the hybrid bonding of HBM3 memory stacks to interposers was causing die warpage exceeding 50μm, leading to micro-bump interconnect failures and 23% yield loss at final test.
Our Solution
We developed a precision laser-assisted debonding and annealing process with real-time warpage compensation. Our femtosecond laser system enabled selective thermal management, reducing stress gradients across the 800mm² interposer while maintaining sub-10μm placement accuracy.
- ✓ Laser thermal annealing profile optimization
- ✓ In-situ warpage metrology integration
- ✓ Automated process control (APC) system
The Results
Within 4 months of production ramp, the customer achieved mass production readiness for their flagship AI training processor. The solution has been scaled across multiple fab lines, supporting annual production volumes exceeding 500,000 units.
Yield & Performance Metrics
"This laser processing solution was a game-changer for our 2.5D packaging technology. The warpage control capabilities enabled us to achieve the interconnect density required for our next-gen AI accelerators while maintaining high volume manufacturing yields."

Common questions about our semiconductor laser processing services
What is the minimum feature size you can achieve?
Our femtosecond laser systems can achieve feature sizes down to 10 μm with positioning accuracy of ±5μm. For TGV applications, we can drill vias as small as 20μm diameter.
What wafer sizes can you process?
We support silicon wafers up to 300mm diameter, as well as SiC, GaAs, GaN, InP, and other compound semiconductor
substrates. Our systems handle thinned wafers down to 50µm thickness.
What is your typical dicing throughput?
TLS dicing achieves separation speeds of 300mm/s, with cycle times of approximately 1.5 seconds per break. This enableshigh-volume production with significantly higher die yield than conventional methods.
What is TLS-Dicing and when should it be used?
Thermal Laser Separation (TLS) uses laser-induced thermal stress to separate materials without mechanical force. It’s ideal for brittle materials like SiC, GaN, and ultra-thin silicon where traditional blade dicing causes chipping.
Do you support advanced packaging applications?
Yes, we provide TSV formation, microvia drlling, and die singulation for 2.5D and 3D IC packaging. Our processes arecompatible with copper pillar, micro-bump, and other advanced interconnect technologies.
How do you ensure cleanroom compatibility?
Our processing area maintains ISO 5 (Class 100) cleanroom standards with continuous particle monitoring. We use specialized debris management systems and non-contact processing methods to prevent contamination.
What is your typical lead time for prototype samples?
Standard prototype lead time is 2-3 weeks from receipt of wafers and approved process parameters. Expedited services are available for urgent projects with delivery in 5-7 business days.
