Latest Patents

One of Martin's latest patents is titled "Edge roughness reduction." This patent describes a method for processing a stack with an etch layer below a mask. The process involves treating the mask with a treatment gas that includes both a sputtering gas and a trimming gas. By providing pulsed TCP power to create a plasma and a pulsed bias, the method effectively reduces edge roughness. The first state of the process allows for sputtering and redeposition of material, while the second state enables chemical trimming of the mask.

Another notable patent is the "Method for reducing line width roughness with plasma pre-etch treatment on photoresist." This method aims to reduce line width roughness (LWR) of features in an etch layer beneath a patterned photoresist mask. The process includes a non-etching plasma pre-etch treatment followed by etching through the pre-treated mask. This innovative approach enhances the precision of etching processes in semiconductor manufacturing.
