Fine Pitch Bump Plating
on Wafers and Substrates

Shinryo is specialized in solder bump forming with minimized bump pitch:
the minimum solder bump pitch is 6μm and the smallest bump diameter is φ3μm.

Our fine pitch bump plating fits to the ongoing trend of miniaturization and high-functionalization of semiconductor devices.

・Shinryo performs the processes of sputtering, photo resist coating, exposure and development, plating, resist stripping, seed layer etching, and reflowing.
・Upon your request, we can flexibly exclude some of the processes, or add some extra process like wafer thinning and dicing.


Plating Solders of Various Melting Points


Shinryo has variety of Pb-free solder for plating, with their melting points ranging from 60℃ to 280℃.

Considering the property, heat resistance, and the use of the devices to apply our plating, we offer you the best suitable solder with our bumping service for each components.




Our newest solder alloy Sn-Bi-In's melting point can be adjusted between 60℃ to 110℃.

Low melting point solders like Sn-Bi-In are developed to reduce damage and warpage on devices and substrates at mounting process.
They are suitable for bonding of low-heat resistant materials
like LEDs, compound semiconductors(CdTe and CZT), and resin substrates.


Flexibility of our Plating Service

We accept not only Si wafers, but also other types of wafers and substrates like Glass, SiC, InP, GaAs, and so on.
Other than wafers and substrates, we also undertake plating on small components like solder balls, metal powders, and wires.

Shinryo is happy to help our customers from the trial stage,
so we gladly accept even 1 wafer or 1 lot of the components for a trial.
When you do not have wafers for TEG production, we can prepare them ourselves. Please feel free to ask.

Application Example : Low-Melting Point Solder Bump Plating
for CdTe/CdZnTe Sensor

Combining our fine pitch bumping technology and low-melting point solder,
we realize best bonding solution for high-end sensor products in medical use.

Issues of Bonding Compound Semiconductors

① On Reflowing Condition：
・Properties of semiconductor change under high temp.　
・Compound semiconductors may get damaged due to the thermal expansion coefficient difference between the substrates or chips.


② On Micro Miniaturization:
・Higher integration is required for minimizing the device and getting clearer CT image.
