Patent ID: 7498830

Claim:
A burn-in apparatus for cooling a semiconductor device to a burn-in temperature; said semiconductor device including a first surface, said first surface being planar, said semiconductor device passing electric current therethrough and generating heat so that a temperature thereof rises above said burn-in temperature and a temperature of said first surface rises; said apparatus comprising: liquid supply means for pressurizing and supplying liquid that cools said semiconductor device, said liquid having a saturation temperature at an atmospheric pressure that is lower than said temperature of said first surface when said temperature of said first surface rises; and a separation member that is in a form of a curved thin sheet that is convex on a side proximal to said first surface and pressable against said first surface so that said separation member lays flat against and covers said first surface and transfers heat from said first surface, said separation member being separable from said first surface; and liquid discharge means for supplying, discharging at a reduced pressure and atomizing said liquid which is supplied from said liquid supply means so that said liquid reaches a surface opposite to said first surface on said separation member.
