Question

What is the Purple Plague? Please explain by using a picture.

Answer 1

Solution ::

Purple plague is purplish in colour and is very brittle, potentially leading to time-based failure of the bonds. Its growth is highly enhanced by the presence of silicon to form ternary compounds.

So basically purple plague Purple plague is a compound formed by intimate contact of gold and aluminum, which appears on silicon planar devices and integrated circuits using gold leads bonded to aluminum thin-film contacts and interconnections, and which seriously degrades the reliability of semiconductor devices.

It is brittle, bright-purple compound, AuAl₂, or about 78.5% Au and 21.5% Al by mass. AuAl₂ is the most stable thermally of the Au–Al intermetallic compounds, with a melting point of 1060 °C (see phase diagram), similar to that of pure gold.
