Hey Liang,

I didn't have much success myself if no groove was used. The ethanol
between the two binding layers will lift the top PDMS slab if it has
nowhere to go during vaporization. You can definitely try it without using
any groove. It's just that you need to come out with an alternative way to
guarantee the bonding.
