Layout design of integrated circuit protects a integrated circuit which means semiconductor integrated circuit, that is, a product, in its intermediate or final form, which uses semiconductor material as a substrate, integrates two or more elements in which at least one is an active element, and some or all of the interconnections in and/or on the substrate, and intends to perform a certain electronic function. Therefore, as long as a chip has a module with independent function and comprising at least one active device, the chip can be registerted as an integrated circuit layout.The benefits of doing so are: 1. a plurality of certificates can be obtained; 2. the integrated circuit layout design printed out is more clear. The term of pretection for layout design of integrated circuit The term of protection for the exclusive right of layout design shall be 10 years, counted from the date of filing an application for registration or from the date on which it was first commercially exploited anywhere in the world, whichever expires earlier.
