A semiconductor device includes a first FinFET device and a second FinFET device. The first FinFET device includes a first gate, a first source, and a first drain. The first FinFET device has a first source/drain proximity. The second FinFET device includes a second gate, a second source, and a second drain. The second FinFET device has a second source/drain proximity that is smaller than the first source/drain proximity. In some embodiments, \the first FinFET device is an Input/Output (I/O) device, and the second FinFET device is a non-I/O device such as a core device. In some embodiments, the greater source/drain proximity of the first FinFET device is due to an extra spacer of the first FinFET device that does not exist for the second FinFET device.

The present invention generally relates to nanofabrication and, in some embodiments, to methods of synthesizing selectively binding patched nanoparticles and the devices that can be made from them. In some embodiments, the invention relates to methods of assembling arbitrarily shaped structures from patched nanocubes and the devices and uses that follow. For example, nanocube building blocks may be patched by stamping their faces with a selectively binding chemical species (e.g. DNA, antibody-antigen pairs, etc.), or by using self-assembly to attach to the nanocubes multiple selectively binding patch species whose immiscibility can be preprogrammed. Arbitrarily shaped structures can then be designed and assembled by deciding which faces will be bonded to each other in some target structure and combining nanocubes that have selectively binding patches on those faces. Other aspects of the invention are also directed to methods of making such nanocubes or other nanoparticles, methods of forming such nanocubes.
