In 0.6um, the minimum lenght of transistors is 0.6um and in the 1um tech. is 1um. In principle you can have smaller transistors in 0.6um which can lead to smaller parasitic capacitance.

"In theory there is no difference between theory and practice..."
At 1um your MOSFET probably looks like the MOSFET cartoon
they show you in introductory courses. Poly gate, self aligned
S/D implant, have a nice day.
By 0.6um almost everybody was doing LDDs and starting to
crowd up against reliability limits, and FETs started to look
less like the simple models. You really had to engineer the
hell out of a 0.6um device to work at 5V and many didn't,
quite. Here's where supply voltages started to decline in
tandem with process node. 3.3V for 0.5um, 2.5V for 0.25um,
etc.
