Claim:
1. A method, comprising: forming first type devices and second type devices on a substrate; epitaxially growing source and drain regions within source/drain cavities of the first type devices and epitaxially growing source and drain regions within source/drain cavities of the second type devices; etching back the source and drain regions for the first type devices to be in closer proximity to a channel region of the first type devices, while protecting the source and drain regions for the second type devices; forming silicide regions on the etched back source and drain regions for the first type devices and the source and drain regions for the second type devices; and removing a cap layer from the first type devices, wherein the silicide regions for the first type devices are in closer proximity to the channel region than the silicide regions for the second type devices, and wherein the removing the cap layer from the first type devices and the etching back of the source and drain regions for the first type devices is provided in a single masking process.
