Latest Patents
Morikawa holds a patent for a semiconductor device and etching apparatus. This patent describes a method for manufacturing a semiconductor device that involves dry-etching a thin film using a resist mask. The process includes patterns where the width of each pattern and the space between neighboring patterns ranges from 32 to 130 nm. The method utilizes a halogenated carbon-containing compound gas, with halogens selected from fluorine, iodine, and bromine. Importantly, the ratio of iodine and bromine is limited to no more than 26% of the total halogen atoms. This innovative etching technique minimizes damage to the resist mask, allowing for precise pattern transfer onto the thin film, which is then used as a mask for further dry-etching of the underlying material.
