We are SJsemi.

A pure play MEOL semiconductor foundry house specializing in 12” bumping, wafer probing and advanced wafer level packaging.

We constantly expect more from our digital lives

More memories

So how can technology keep up with demands?

To do more, you have to think BIG and create small

So small, the process is invisible to the naked eye

Our technology happens here

On a scale 450 x smaller than a micro SIM

Our copper bumps interconnect millions of transistors

Enabling more power

and ultimately more possibilities

Now that you know what we do, find out how we do it
