Abstract
A method of making a ROM structure includes the operations of forming an active area having a channel, a source region, and a drain region; depositing a gate electrode over the channel; depositing a conductive line over at least one of the source region and the drain region; adding dopants to the source region and the drain region of the active area; forming contacts to the gate electrode, the source region, and the drain; depositing a power rail, a bit line, and at least one word line of the integrated circuit against the contacts; and dividing the active area with a trench isolation structure to electrically isolate the gate electrode from the source region and the drain region.
