Description

TECHNICAL FIELD

[0001] The present application relates to the field of semiconductor handling, and in particular to a sample storage and handling system. BACKGROUND

[0002] Processes for manufacturing semiconductors have stringent standards that require wafers and packaged chips to be tested in a variety of ways to ensure that they can survive the most extreme environments and hazardous conditions. One phase of the testing process is to evaluate whether the chips can operate at extremely low and high temperatures. Depending on the standards for a particular 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. Some standards require multiple repeated cycles of these extreme temperatures, alternating between very high and very low temperatures, for as many as 100, 500, 1000, 5000 times, or until the chip fails. Other standards can require rapid changes in temperature, sometimes referred to as "thermal shocks," and apply these shocks to the packaged chip for hundreds or thousands of times.

[0003] There are currently two types of equipment designs used in the market. In one version, the sample being tested is fixed in a chamber, and separate hot and cold chambers are connected to this chamber by air ducts. The equipment automatically opens or closes different valves by programming and uses fans to blow hot or cold air through the sample area. This method is the simplest in design and has the lowest manufacturing cost, but the energy consumption is extremely high because the entire chamber needs to be heated and cooled for each cycle. In addition, the air flow is not very uniform, and the time required to complete all cycles is long. The second method 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. This seems more efficient at first glance because there is no separate heating and cooling chamber for each cycle. 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.
