IC refers to a semiconductor integrated circuit that is based on semiconductor materials, and at least two components including at least one active component and some or all of the interconnection lines are integrated in or on the substrate to perform an electronically functional intermediate or final product.

The layout design of integrated circuits is protected by the one-way method. The right holders can submit relevant application documents to the national intellectual property administration for original layout designs. In addition to filling out and submitting an application form for layout design of integrated circuits, you should submit a copy or drawing of the layout design of an integrated circuit. For layout designs that have been put into use, you also need to submit a sample of the integrated circuit containing the layout design to obtain the exclusive right of the layout design.
