    Abstract: A method for forming both n and p wells in a semiconductor substrate using a single photolithography masking step, a non-conformal oxide layer and a chemical-mechanical polish step. A screen oxide layer is formed on a semiconductor substrate. A barrier layer is formed on the screen oxide layer. The barrier layer is patterned to form a first opening in the barrier layer over regions of the substrate where first wells will be formed. We implant impurities of a first conductivity type into the substrate to form first wells. In a key step, a non-conformal oxide layer is formed over the first well regions and the barrier layer. It is critical that the non-conformal oxide layer formed using a HDPCVD process. The non-conformal oxide layer is chemical-mechanical polished stopping at the barrier layer. The barrier layer is removed using a selective etch, to form second openings in the remaining non-conformal oxide layer over areas where second well will be formed in the substrate. Using the remaining non-conformal oxide as a mask, we implant impurities of the second conductivity type through the second openings to form second wells. The remaining non-conformal oxide layer and the screen oxide layer are removed.

    Abstract: A new method for forming ultra-shallow junctions for PMOSFET while reducing short channel effects is described. A semiconductor substrate wafer is provided wherein there is at least one NMOS active area and at least one PMOS active area. Gate electrodes are formed in both the NMOS and PMOS areas. N-type source/drain extensions are implanted into the NMOS area. The wafer is annealed whereby the n-type source/drain extensions are driven in. Thereafter, p-type source/drain extensions are implanted in the PMOS area wherein the p-type source/drain extensions are not subjected to an annealing step. Spacers are formed on sidewalls of the NMOS and PMOS gate electrodes. Source/drain regions are implanted into the NMOS and PMOS areas wherein the source/drain regions are self-aligned to the spacers to complete formation of an integrated circuit device.
