Patent ID: 8916423

Claim:
A method of manufacturing a semiconductor device, the method comprising: forming a first electrode on a first semiconductor substrate, the first electrode including a first portion protruding from a main surface of the first semiconductor substrate; coating the main surface and the first electrode with an insulating material having a first viscosity at a first temperature, having a second viscosity lower than the first viscosity at a second temperature higher than the first temperature, and having a third viscosity higher than the second viscosity at a third temperature higher than the second temperature; and forming a first insulating film by curing the insulating material, wherein the forming the first insulating film includes: after the coating, bringing the insulating material having the first viscosity to the second viscosity by heating the insulating material under a first condition; and after the bringing the insulating material to the second viscosity, bringing the insulating material to the third viscosity by heating the insulating material under a second condition, and a temperature rising rate under the first condition for the first semiconductor substrate is different from a temperature rising rate under the second condition.
