    摘要: Disclosed is a method of forming an integrated circuit structure having first-type transistors, such as P-type field effect transistors (PFETs) and complementary second-type transistors, such as N-type field effect transistors (NFETs) on the same substrate. More specifically, the invention forms gate conductors above channel regions in the substrate, sidewall spacers adjacent the gate conductors, and source and drain extensions in the substrate. The sidewall spacers are larger (extend further from the gate conductor) in the PFETs than in the NFETs. The sidewall spacers align the source and drain extensions during the implanting process. Therefore, the larger sidewall spacers position (align) the source and drain implants further from the channel region for the PFETs when compared to the NFETs. Then, during the subsequent annealing processes, the faster moving PFET impurities will be restrained from diffusing too far into the channel region under the gate conductor. This prevents the short channel effect that occurs when the source and drain impurities extend too far beneath the gate conductor and short out the channel region.

    摘要: A method for manufacturing a device includes mapping extreme vertical boundary conditions of a mask layer based on vertical edges of a deposited first layer and a second layer. The mask layer is deposited over portions of the second layer based on the mapping step. The exposed area of the second layer is etched to form a smooth boundary between the first layer and the second layer. The resist layer is stripped. The resulting device is an improved PFET device and NFET device with a smooth boundary between the first and second layers such that a contact can be formed at the smooth boundary without over etching other areas of the device.
