System-in-Package (SiP) Manufacturing
System-in-Package, or SiP, enables heterogeneous integration by placing multiple chips with different functions (memory, logic, sensors) on a single substrate. SiP supports continued system performance increases without relying solely on transistor-level scaling. Laser processing is widely used in SiP for micro-vias, singulation, thinning, and substrate cutting across ceramics, organics, and glass.

SiP Manufacturing Challenges
SiP production requires micrometer accuracy and material-specific processes. Main challenges:
- Micro-via formation
- Diameters from a few microns to ~200 µm.
- Chemical etching works for silicon and some glass, but not for many ceramics or organic laminates.
- Etching adds waste, steps, and cost.
- Material cutting and singulation
- Requires low collateral damage and tight kerf control as feature sizes shrink.
- Thin-material handling
- Non-contact processing reduces mechanical damage and increases yield.
- Material diversity
- Ceramics, ABF, FR4, glass, laminates with embedded copper traces respond differently to mechanical saws, etching, and lasers.
Laser approaches for SiP
Shorter wavelengths and shorter pulse widths reduce the heat-affected zone, improving precision and yield.
Ultrashort pulse (USP) vs nanosecond (ns) lasers
- Nanosecond lasers
- Good for many singulation and drilling tasks at UV and green wavelengths.
- Higher thermal load can degrade dense layouts.
- Ultrashort pulse (picosecond and femtosecond) lasers
- High peak power induces nonlinear absorption and near-instant material removal.
- Produce negligible HAZ, enabling high-precision drilling and cutting with reduced part failure.
Picosecond Lasers
Typical uses by wavelength:
- UV: micro-vias in ceramic, organic, glass interposers.
- UV and green: ceramic interposer cutting, depaneling, silicon scribing/dicing.
- IR: glass cutting.
IceFyre® Picosecond Lasers: Spectra-Physics IceFyre picosecond lasers set a new standard for picosecond micromachining and can provide the ultimate solutions for SiP manufacturing. The UV version enables premium quality drilling of micro-vias through ceramic, organic and glass interposers. Both the UV and green versions are great for cutting ceramic interposers, depaneling and scribing and dicing silicon dies. Additionally, the IR version can be used to cut glass interposers.

Nanosecond Lasers
Use cases: high-throughput micro-via drilling, interposer cutting, depaneling, scribing/dicing.
- Talon® Ace™ Lasers: Delivering an industry-leading >100 Watts of UV power, Talon Ace offers the lowest cost-per-Watt and cost of ownership for high power nanosecond UV lasers. This laser can be employed for a whole host of applications including drilling micro-vias through ceramic, organic laminate and glass interposers, cutting ceramic and organic laminate interposers, depaneling, and scribing and dicing dies. Talon Ace also includes our proprietary TimeShift programmable burst-mode technology for the most versatile pulse control, leading to increased process speed and quality.
- Talon® Nanosecond Lasers: For the best combination of performance, reliability and cost in SiP laser manufacturing, Spectra-Physics Talon lasers deliver excellent results. Talon works exceptionally well for cutting ceramic and organic laminate interposers, depaneling and scribing and dicing silicon dies. The UV version in particular is also able to drill micro-vias through ceramic and organic interposers. The Talon provides high quality results, but its cuts and drills may not be as pristine as the IceFyre’s. Talon’s advantage over IceFyre, though, is that it can cut and drill faster.
- Quasar® High-Power Nanosecond Lasers: Other lasers highly suited for SiP manufacturing are the Spectra-Physics Quasar® and Talon® Ace nanosecond series of lasers. The Talon Ace UV100 is the highest-powered single mode UV laser in the industry, so it delivers fast micromachining and provides 24/7 industrial reliability. Like the IceFyre and Talon, the UV and green versions of the Quasar and Talon Ace can also be used for depaneling, scribing and dicing dies. And like the UV version of the IceFyre, the Quasar UV and Talon Ace UV can also drill micro-vias through ceramic, organic and glass interposers.
