    摘要: Methods of forming a mask for implanting a substrate and implanting using an implant stopping layer with a photoresist provide lower aspect ratio masks that cause minimal damage to trench isolations in the substrate during removal of the mask. In one embodiment, a method of forming a mask includes: depositing an implant stopping layer over the substrate; depositing a photoresist over the implant stopping layer, the implant stopping layer having a density greater than the photoresist; forming a pattern in the photoresist by removing a portion of the photoresist to expose the implant stopping layer; and transferring the pattern into the implant stopping layer by etching to form the mask. The implant stopping layer may include: hydrogenated germanium carbide, nitrogenated germanium carbide, fluorinated germanium carbide, and/or amorphous germanium carbon hydride (GeHX), where X includes carbon. The methods/mask reduce scattering during implanting because the mask has higher density than conventional masks.

    摘要: Two different gate conductor dielectric caps are used in the array and support device regions so that the bitline contact can be fabricated in the array region, but a thinner hard mask can be used for better linewidth control in the support device region. The thinner dielectric cap is made into dielectric spacers in the array device regions during support mask etching. These dielectric spacers allow for the array gate conductor resist line to be made-smaller than the final gate conductor linewidth. This widens the array gate conductor processing window. The second dielectric cap layer improves linewidth control for the support devices and the array devices. Two separate gate conductor lithography steps and gate conductor dielectric etches are carried out in the present invention to optimize the gate conductor linewidth control in the array and support device regions. The gate conductors in the array and support devices regions are etched simultaneously to reduce production cost. In additional embodiments of the invention, dual workfunction support device transistors with or without salicide can be fabricated with an array including borderless contacts.
