Solutions for
Advanced Semiconductor Packaging

Advanced semiconductor packaging plays a critical role in the evolution of AI and high-performance devices.

To enable high-speed signal transmission and reduce power consumption, multiple chips are integrated into 2.xD and 3D architectures using interposers. At the same time, feature sizes continue to shrink and designs become more complex.

As device complexity increases, manufacturing is shifting from wafer based processes to panel based processes to improve efficiency and scalability, accelerating R&D and innovation.

As equipment scales to support these panel based processes, measurement systems must deliver both high throughput and highly accurate positioning.

With extensive experience in semiconductor packaging metrology, Mitutoyo helps improve quality and reliability through advanced measurement technologies.

Facing These Challenges?

Challenge 1
Limitations of Optical Microscopy for Fine Features
As interposer wiring becomes finer and aspect ratios increase, conventional optical microscopy alone is no longer sufficient for accurate evaluation. There is also a need to measure large panels up to 500 mm in size.
Challenge 2
Need for Non-Destructive Internal Inspection During Production
X-ray CT inspection requires time consuming pre-processing, while SAT inspection requires immersion in water. Both methods make it difficult to integrate inspection into in-line processes.
Challenge 3
Need for Accurate Measurement of Design Compliance
While visual inspection systems are used for external checks, accurately measuring size and positional accuracy remains a challenge. Conventional measurement systems are often too slow.

Solutions for
Power Semiconductors

Power semiconductors play a critical role in advancing a decarbonized society, driven by trends such as vehicle electrification and the expansion of green energy.

As devices become smaller and more efficient while supporting higher power capacity and voltage, new materials such as SiC and GaN are increasingly being adopted.

In this evolving landscape, Mitutoyo’s QV Pro, equipped with the Stream Function and Tracking Auto Focus (TAF), enables high throughput, high precision measurement of the position and tilt of tens of thousands of dies on a substrate.

This helps improve product performance and reliability.

Facing These Challenges?

Challenge 1
Time-Consuming Measurement of Die Position and Tilt
Accurate measurement of die position and tilt across all dies is required, but conventional systems take too much time, increasing lead time, while optical inspection systems lack sufficient accuracy.
Challenge 2
Pin Misalignment Caused by Substrate and Lead Frame Warpage
Warpage of substrates and lead frames can cause pin misalignment, leading to frequent line stoppages and reduced productivity.
Challenge 3
Low Efficiency in Manual Workpiece Handling
Manual loading and unloading of workpieces result in long downtime, limiting productivity and preventing unattended operation.

Solve These Challenges
with Mitutoyo Solutions

Solution01
QV Pro’s Stream Function Reduces Takt Time
for Full-Die Position Measurement by Up to 80%
The QV Pro series features strobe illumination as standard across all models.

By synchronizing stage movement with strobe illumination, the Stream Function enables continuous measurement without stopping the system.

This significantly reduces the lead time required to acquire position data for all dies.
Solution02
QV Pro’s Tracking Auto Focus (TAF) Instantly Adjusts to Maintain Focus Regardless of Warpage or Tilt
The laser based Tracking Auto Focus (TAF) function enables real time tracking of surface variations in the workpiece.

It instantly adjusts focus to compensate for substrate warpage and die tilt, reducing line stoppages caused by focus misalignment.
