Latest Patents

Gandy's latest patents include innovative methods aimed at reducing metal dishing during CMP. One of his key inventions is a protective barrier layer made from materials such as titanium or titanium nitride. This layer is designed to ensure that the removal process during CMP is primarily mechanical rather than chemical. By strategically removing upper topological regions of the barrier layer first, Gandy's method allows for the tungsten beneath to be exposed and removed, while still protecting lower topological regions. This results in a substantially planar CMP patterned tungsten that avoids dishing, even in large area structures like MOS capacitors.
