Latest Patents

Sonny Li holds a patent for a method titled "Porous low-k dielectric etch." This patent describes a process that involves performing a plurality of cycles in a plasma processing chamber. Each cycle consists of a deposition phase and an activation phase. During the deposition phase, a deposition gas, which includes fluorocarbon and/or hydrofluorocarbon gas, is flowed into the chamber. A plasma is created using this gas, leading to the deposition of a fluorocarbon or hydrofluorocarbon containing layer. The flow of the deposition gas is then stopped. In the activation phase, an activation gas, which includes a noble gas and a carbon etching additive, is introduced. A plasma is generated from this activation gas, and an activation bias is applied, which facilitates the etching of the low-k dielectric layer while consuming the previously deposited layer.
