Abstract: A method for testing a semiconductor device comprises obtaining an alignment signal between one or more auxiliary pins of a test probe and one or more auxiliary pads of a test key of the semiconductor device before a probing test of the semiconductor device. The obtaining of the alignment signal comprises: performing a vertical alignment between the one or more auxiliary pins of the test probe and the one or more auxiliary pads of the test key; and gradually reducing a vertical distance between the one or more auxiliary pins of the test probe and the one or more auxiliary pads of the test key for bringing into an electrical contact until the alignment signal there-between satisfies an alignment condition.

Abstract: A henhouse includes a gable, a sidewall, and a roof. An inner chamber parallel to the sidewall is provided in the middle of the henhouse. The inner chamber includes an inner wall parallel to the sidewall and an inner roof. A partition is provided between the sidewall and the inner wall. An air inlet plate is provided between the two inner walls located below the inner roof. A pressure chamber is formed between the inner roof and the air inlet plate. A premixing chamber is formed between the inner roof and the roof. A plurality of fans and air inlet windows are uniformly provided on the inner roof. A plurality of air inlet holes and small inlet windows are uniformly provided on the air inlet plate. A plurality of wet curtains and an air vent are provided on the sidewall. A plurality of air outlet slots are uniformly provided on the inner wall.

Abstract: A premixed underground ventilated henhouse includes a gable, a sidewall, a roof and a floor. An inner chamber is further provided in the middle of the henhouse. A partition is hermetically provided between the sidewall and an inner wall. An air inlet plate is provided between the two inner walls. A plurality of fans and a plurality of air inlet windows are uniformly provided on an inner roof. A plurality of wet curtains and an air vent are provided on the sidewall. Air outlet slots are uniformly provided on the inner wall. An underground exhaust bunker is provided under the floor. A vent pipe and a fan are provided on one side of the underground exhaust bunker. An air outlet is provided at an upper end of the vent pipe.
