Abstract
An image sensor package, a system, and a method for counting fine particles by using a virtual grid line are provided. The image sensor package includes an image sensor array, a grid pattern layer formed on an outer area of the image sensor array and including a plurality of protruding patterns spaced apart from each other while protruding toward the central area of the image sensor array to form a virtual grid line, a dam pattern layer formed on the grid pattern layer, having a specific height, and configured to form a channel or a chamber for receiving the fine particles to be counted, and a cover glass formed on the dam pattern layer.
