Read More About What We Can Offer
We serve multiple industries with wide range of applications. Take a look at some examples and the benefits that we can offer you.
Which wafer sizes can you bond?
Currently our lab is equipped to handle up to 12” wafers. This is limited by customer needs and we are ready to move into panels.
How fast is the bonding process?
Being a linear process the bonding speed depends on the wafer design – the process is much faster when the die number per wafer is lower.
However, since the whole bonding can be done in one step without preheating or cooling down, the effective speed is faster that with traditional methods.
Do you have a job shop in the US?
Right now all of our service manufacturing is done in Finland, Europe. We are currently working with our customers to build a new process center in California.
What materials can you bond?
We have done multiple successful projects using glass to glass bonding and glass to silicon bonding.
Almost all glass types are suitable. We have used Borofloat33, D263T, ENA1, soda lime, fused silica and different types of quartz glass.
Sapphire to sapphire is still considered “under development”.
Are there any additive layers or coatings needed?
No. No additives or coatings are needed during the bonding process.
Can I package heat sensitive components?
Absolutely. With our process the Heat Affected Zone (HAZ) is extremely small.
We have measured under 1’C change just 100 um from the bonding line.
Is it possible to have a vacuum inside the cavity?
Yes. We have developed a proprietary technology to achieve a high vacuum and seal with minimal heat load.
