Latest Patents

Matsubara holds a patent for a method titled "Selective in-situ carbon-based mask protection." This patent describes a process for etching an underlying layer that includes a pretreatment step, a reaction step, and an etch step. The pretreatment step involves exposing surfaces of a patterned carbon-containing layer to oxygen, forming C—O bonds at the surfaces, with or without plasma. The reaction step entails exposing these C—O bonds to an oxygen-reactive precursor to selectively create a mask protection layer. The etch step follows, where an etchant gas is flowed, and plasma is excited to etch the underlying layer using the patterned carbon-containing layer as an etch mask. This innovative approach allows for flexibility in performing the steps consecutively, concurrently, or in cycles.
