Problem

Problem

Teradyne had less than a 7 month supply of a critical bipolar ASIC chip used in a production tester. Although they had paid for a new design by a large domestic semiconductor firm, the part did not work properly in their system. Teradyne did not have a schematic or spice models of the original part or know the details of the manufacturing process, they did have the mask database.

Solution

Solution

iSine scoured the world for a fab that could produce a bipolar chip similar to the obsolete part. They found a semiconductor fab in Europe that used a related process to the original. In and extremely short turnaround of less than four month, iSine converted the mask database into a new design that met the design rules of the new fab.

Results

Results

The new high performance bipolar chip was completed in record time and worked in first silicon. It was a direct replacement for the obsolete chip. This averted the production line shut-down of Teradyne's best selling tester.
