The lithium transition metal phosphate includes a carbon coating layer formed on a surface thereof, and a ratio (B/A) of a total weight (B) of the fluorine-based binder to a total weight (A) of carbon of the conductive material and the lithium transition metal phosphate in the positive electrode active material layer is 0.7 to 1.7.

Abstract: Disclosed herein is a multi-channel device for detecting plasma at an ultra-fast speed, including: a first antenna module connected to a first output terminal in contact with a substrate on a chuck of a process chamber and extending to ground, and receiving a first leakage current leaking through the substrate to increase reception sensitivity of the leakage current; a first current detection module detecting the first leakage current; a current measurement module receiving the first leakage current output from the first current detection module, and extracting the received first leakage current for each predetermined period to generate a first leakage current measurement information; and a control module comparing the first leakage current measurement information with a reference value to generate first arcing occurrence information.

Abstract: The inventive concept provides a substrate treating method. The substrate treating method includes treating an edge region of a substrate using a plasma; and acquiring an image to be determined by imaging a substrate on which a treatment has been completed in the treating the edge region, comparing the image to be determined with an image stored in a database, and determining whether a substrate treated in the treating the edge region is defective or not, and wherein the image stored in the database is a defective image of a substrate which has been determined as defective, which is previously stored in the database in the acquiring the image to be determined.
