Abstract:
1. An apparatus comprising: a chamber having a top side to receive a semiconductor device under test (DUT); a solid immersion lens (SIL) adapted within the chamber to receive optical energy from the semiconductor DUT during a test operation; and a head assembly adapted about the SIL, the head assembly including a first plurality of jets configured in a radial pattern along a single linear radius of the head, the radial pattern extending from a central portion to a substantial periphery of the head assembly, each of the first plurality of jets to expel a non-spray liquid coolant single-phase stream to cool the semiconductor DUT, wherein the streams are to collectively and initially contact a surface of the semiconductor DUT with a radial impingement pattern along the single linear radius so that the streams collectively travel from a central portion of the semiconductor DUT surface to a peripheral portion of the semiconductor DUT surface.
