Hi Xiaohui

I think SU-8 generally tends to degrade (i.e. molecular bonds breaking)
before the temperature is sufficient to cause it to reflow. I think the
degradation temperature is around 300 Deg C. So you could try to heat to
between 250-280 Deg C for a period of time to see what happens. Let me know
if you get reflow.

Regards,

Michael
