A chip placement method includes the steps of: (a) determining the order of placement of integrated circuit chips by the features of the chip modules, (b) generating pix-level masks from the status of the placed chips and the next two chips to be placed, (c) extracting local and global features from the masks by convolutional neural networks, and (d) selecting the placement position by merged features and a congestion threshold. The method is carried out by computer apparatus with a storage medium.
