Chip-level ALD moisture barrier for components on tape

Chip-Level Moisture Barrier

 

The challenge

The device did not pass the highly accelerated stress test (HAST), which tests the device performance after long term high humidity high temperature exposure. The side-walls of the device had to be protected against moisture.

The customer

A leading power semiconductor device manufacturer

Beneq solution

A conformal ALD Al2O3/TiO2 multilayer moisture barrier was deposited on the die-level with the Beneq P400A high-capacity batch ALD system. A low-temperature process was used to enable coating while the die are on tape.
