I'm looking for a schematic for a square wave oscillator which draws
around 10uA, powered by 2 to 5V and oscillates at around 100kHz with a
50% duty cycle. I tried out some schematics around a 4007 but none can
meet all the requirements.

any suggestions here?

An MSP430 micro might be able to do that, worth checking. Not 5V though.

I'd investigate the oscillator in the 4046. Beautiful symmetry, and it's
pretty low-power too. Hope you're not trying to drive much of a load
though.
