Latest Patents

Among his latest patents is the "Reference wafer for calibration and method for fabricating the same." This innovative reference wafer is designed to maintain laser accuracy and calibrate both a camera and a laser used in semiconductor equipment. The structure of the reference wafer includes a first anti-reflection layer, an adhesive layer, a light absorption layer, and a second anti-reflection layer, all stacked over a substrate. Additionally, it features a light reflection layer formed over the second anti-reflection layer and a protection layer over the light reflection layer.

Another notable patent is the "Method for forming pattern using hard mask." This method involves forming a pattern in a semiconductor device by first creating an etch target layer. A hard mask is then formed over this layer, consisting of a multiple-layer stack structure that includes a bottom layer, a transformed layer, and an upper layer. The transformed layer is created by altering the surface of the bottom layer, followed by the etching of both the hard mask and the etch target layer.
