Title: Chen Liu: Innovator in Road Detection and Semiconductor Packaging

Introduction

Chen Liu is a prominent inventor based in Xi'an, China, known for his contributions to the fields of road detection technology and semiconductor device packaging. With a total of two patents to his name, Liu has made significant strides in enhancing vehicle technology and semiconductor structures.

Latest Patents

Liu's latest patents include a "Method of Road Detection Based on Internet of Vehicles." This innovative method applies to vehicle terminals and involves obtaining a target road image captured by an image collection terminal. The image is then input into an improved YOLOv3 network for feature extraction, utilizing a backbone network of dense connection to obtain feature images at different scales. The method further employs feature fusion through an improved feature pyramid network (FPN) to yield prediction results, which include attribute information such as positions and categories of objects in the target road image. The improved YOLOv3 enhances the original network by replacing residual modules with dense connection modules, optimizing feature extraction and fusion processes.

Another notable patent is the "Package Structure for Semiconductor Device and Preparation Method Thereof." This disclosure presents a three-layer film package structure for a semiconductor device, consisting of a first SiO film, a SiN film, and a second SiO film stacked in that order. The first SiO film is created through a thermal oxidation process, while the SiN film is formed via a low-pressure chemical vapor deposition process. The second SiO film is produced using a low-temperature atomic layer deposition process, and the patent also outlines a method for preparing this package structure.
