An interference pattern is, by definition, an accumulation of many 
photons. You cannot get an interference pattern from one photon any more 
than you can get a landscape painting from one dollop of green paint.

However, what is true is that an interference pattern will be formed 
even if you fire photons one at a time through a double-slit apparatus, 
such that the fired photon lands before the next one is fired, and so 
you KNOW that no two fired photons are interfering with each other.

Interestingly, this I believe is true regardless of the physical 
dimensions of the apparatus, with the caveat that the angle between any 
maximum in the interference pattern and the adjacent minimum is 
determined by the ratio of the wavelength and the separation distance 
between the slits. (So it's possible to have that ratio such that the 
angle mentioned is more than 90 degrees, in which case you wouldn't see 
the pattern anyway.)
