A method for manufacturing integrated circuits (“ICs”) is disclosed. The method pertains to providing third-party technology in the form of an IC design library to foundry customers for designing IC products using alternate rule sets. Aggressive rules pertaining to IC layout are used to reduce device size, resulting in more device per wafer for the customer. The method includes a library creator creating a slim cell library, a slim cell library being provided to a customer to enable the customer to generate a slim IC design; an IC fabricator charging the customer a per-wafer premium to fabricate the slim IC design; the IC fabricator providing a first portion of the premium to a first entity, wherein the first entity is a contributor of technology for enabling creation of the slim cell library; and the IC fabricator providing a second portion of the premium to the library creator.
