Microwaving chicken before frying
Microwaving raw meats is quite tricky, as its difficult to cook evenly. A different method would be best, sous vide probably being the most reliable. The machines can be pricey, but I've had good luck with a pot of water, a candy thermometer, and some ziplock bags (especially if you're only looking to par cook). You can find some great tutorials with a quick Google search.

If you have no option but the microwave, make sure that you  cook for short periods, rotating and flipping the meat often to prevent uneven cooking. I'd also recommend cooking in a container with a small amount of water and a cover of some kind (but not sealed) to take advantage of some steam.
