Now I am about to do PCB artwork for MMA8653FCR1.
If I locate some patterns on the immediate opposite layer of mounting position, could it be a reason of malfunction?
Hello YK Jung,
No, it should be fine as long as you don't place vias underneath the device.
You might find useful page 41 of the datasheet:

Hope it helps!
