Methods of producing integrated circuits are provided. An exemplary method includes patterning a source line photoresist mask to overlie a source line area of a substrate while exposing a drain line area. The source line area is between a first and second memory cell and the drain line area is between the second and a third memory cell. A source line is formed in the source line area. A source line dielectric is concurrently formed overlying the source line while a drain line dielectric is formed overlying a drain line area. A drain line photoresist mask is patterned to overlie the source line in an active section while exposing the source line in a strap section, and while exposing the drain line area. The drain line dielectric is removed from over the drain line area while a thickness of the source line dielectric in the strap section is reduced.
