Minimal foundry

Package on IC Chip without Bump!

We Provide a low-profile package 80µm or less!

Features of PMT Foundry

Speed Flexibility Economy

PMT Foundry offers excellent value in speed, economy, and flexibility.


Providing thinner package in a short time, development time can be shortened.


Both electronic substrate and photomask are not required because of using mask-less exposure.


Using a mask-less exposure system, designing RDL pattern becomes more flexible.

Flexible Process Design!

We flexibly respond to customer’s requests by using packaging and plating technology with high process integration capability and wide experience.
● KGD without solder bump can be accepted.
● PMT Foundry easily supports MOA orders with few IC dies.
● Low-profile package because of no electronic substrate.

● Signal Integrity

Reduction of electric resistance and parasitic capacitance with RDL helps better signal integrity.

● Heat Dissipation

Lower thermal resistance and better heat dissipation because of thinner package.

● Extremely Thin Package

Capable to expose the back side of IC die embedded in mold resin.
