Please assume a semiconductor chip like IGBT or MOSFET heated by a specific power loss. It is found that the more the power loss is, the more severe the chip's temperature distribution non-uniformity is. Could you please explain why?

  • \$\begingroup\$ Take a piece of metal, heat it with a torch, the more you heat it, the more non uniformity of the heat you have \$\endgroup\$ – PlasmaHH May 28 '18 at 21:04
  • \$\begingroup\$ If you normalize your distribution to the amount of injected heat, the distribution non-uniformity will likely stay the same. But obviously more heat equals to higher "bump". What needs to be explained here? \$\endgroup\$ – Ale..chenski May 29 '18 at 0:05

'' yes, the normalized parameter is called thermal resistance which one can assume it as a constant parameter. \$\endgroup\$ – Mohsen May 29 '18 at 1:54
