mechanical and electrostatic damage.
- Layer 1: Oxide (undopped oxide 0.135 m)
- Layer 2: PSG (dopped oxide, 0.43 m)
- Layer 3: Oxynitride (top layer, 0.34 m)
The bond pad size is that of the passivation opening. The metal overlaps the bond pad passivation by at
least 0.1 mil.
Metal Pad Composition is 98.5% Aluminum with 1% Si and 0.5% Cu.
As the die thickness decreases, susceptibility to cracking increases. It is recommended that the die be as
thick as the application will allow.
The Die Passivation thickness can vary by device depending on the mask set used:
The conversion rate is 25.4 m/mil.
