Abstract
A semiconductor device test assembly includes a heat sink having a surface configured to support a device under test, an inner bellow, an outer bellow at least partially surrounding the inner bellow, and a fluid channel within the inner bellow for providing a fluid to the heat sink. The semiconductor device test assembly can further include an air adjustment unit for adjusting an air pressure in the outer bellow, so as to adjust a contact force between the heat sink and the device under test.
