Description

[0002] Semiconductors and computer chips are critical and diverse components of almost every industry in the world, and the process of manufacturing semiconductors has strict standards that require wafers and packaged chips to be tested in various ways to ensure that they can survive in the most extreme environments and dangerous conditions. One stage of the testing process is to assess whether the chips can work at extremely low and high temperatures. Depending on the standards of the specific type of chip, the temperature range can be -20°C to +40°C, -50°C to +60°C, -65°C to +150°C, or a combination of various temperatures.

[0003] The current market for high and low temperature testing of chips uses two chambers that maintain cold and hot temperatures. An elevator moves the sample between the two chambers, and the air inside the chambers is blown to change the temperature of the sample. However, the elevator structure retains a large amount of heat that must be exchanged in each cycle, and the method of elevating the elevator allows heat to leak between the chambers, and the close proximity of the hot and cold chambers allows heat to transfer between them, so an intermediate isolation chamber is added between the two chambers, and a thermal insulation door is added at the outlet of the two chambers.

[0004] The existing thermal insulation door design is mostly swung to one side through a hinge, similar to the doors in a house, but because of the large space required to open and close the door, it will cause higher heat transfer through the chamber wall, and the advanced way is to let the door slide up and down through the wall or ceiling to reduce the space, but the cavity required for the door to retract also becomes a source of heat transfer, and also increases the complexity of the design.
