    摘要: Methods for forming memory devices and integrated circuitry, for example, DRAM circuitry, structures and devices resulting from such methods, and systems that incorporate the devices are provided. In some embodiments, the method includes forming a metallized contact to an active area in a silicon substrate in a peripheral circuitry area and a metallized contact to a polysilicon plug in a memory cell array area by forming a first opening to expose the active area at the peripheral circuitry area, chemical vapor depositing a titanium layer over the dielectric layer and into the first opening to form a titanium silicide layer over the active area in the silicon substrate, removing the titanium layer selective to the titanium silicide layer, forming a second opening in the dielectric layer to expose the polysilicon plug at the memory cell array area, and forming metal contacts within the first and second openings to the active area and the exposed polysilicon plug.

    摘要: A photoresist processing method includes treating a substrate with a sulfur-containing substance. A positive-tone photoresist is applied on and in contact with the treated substrate. The method includes selectively exposing a portion of the photoresist to actinic energy and developing the photoresist to remove the exposed portion and to form a photoresist pattern on the substrate. The treating with a sulfur-containing substance reduces an amount of residual photoresist intended for removal compared to an amount of residual photoresist that remains without the treating.
