Design and fabrication often see the same thing differently.
One speaks in simulations and specifications.
The other speaks in tolerances and yield.
Both are right. Both want the same thing — reliability.
But somewhere between intent and execution, meaning gets lost.
And when that happens, precision begins to drift.
A Lesson from Space
In 1999, NASA lost the Mars Climate Orbiter.
Not because of poor design, or faulty hardware, or weak testing — but because two teams used different units of measurement. One worked in imperial. The other in metric.
The result? A $327 million spacecraft entered the Martian atmosphere at the wrong trajectory and disintegrated.
No malfunction. No defect. Just miscommunication.
That small gap between assumption and understanding can destroy the most sophisticated projects. And in microfabrication, that gap hides everywhere.
It Happens Here Too
In thin-film manufacturing, precision is measured in microns — and so are misunderstandings.
A plating thickness that wasn’t specified.
A via size that wasn’t updated after design change.
A tolerance buried deep in an email thread.
We once worked on a design that called for Ti/Au metallization. On paper, it looked perfect. But in process, it risked delamination.
After a short call, we switched to TiW/Au, tuned the recipe, and the first lot passed qualification.
No redesign. Just shared understanding.
When design and fab talk early, small errors stay small.
Speaking the Same Language
Design for Manufacturability (DfM) isn’t about policing creativity. It’s about translation.
It connects the imagination of design with the discipline of fabrication.
A good DfM process doesn’t limit innovation — it sustains it.
When both sides speak the same language, what gets built is what was intended.
At Vajra Microsystems, we try to keep this bridge alive.
We share process boundaries — minimum via sizes, layer stack guidelines, metal combinations, and polyimide parameters — so design intent translates cleanly into fabrication success.
Because clarity before fabrication is cheaper than discovery after testing.
A Simple Truth
The best designs aren’t just clever.
They’re buildable.
The best fabs don’t just follow drawings.
They understand intent.
Every wafer teaches this truth:
Trust compounds quietly — one project, one conversation at a time.
The Vajra Approach
Our mission is simple — help engineers build things that work the first time.
That means transparent communication, design feedback loops, and shared process wisdom between design and fab teams.
From RF filters and microwave circuits to implantable medical devices and sapphire or diamond substrates, our goal remains the same — bridge intent and execution through precision, reliability, and understanding.
