A method and system of arranging advertisements on a network such as the Internet enables a potential media owner or affiliate to sell its ad space on a network media to an advertiser at a discretion of the affiliate simply by accepting advertiser’s conditions for the advertisement. That method comprises forming a hard mask and an etch stop layer on a patterned sacrificial gate electrode layer. During the assembling operation, a shim for length adjustment having a thickness corresponding to the displacements is selected, and this shim is arranged between the cell component and the pressurizing component.
