Patent number: 11927621Abstract: Cryogenic testing systems for testing electronic components such as wafers under cryogenic conditions are provided. The novel designs enable fast throughput by use of a cryogenically maintained test surface to which wafers may be rapidly introduced, cooled, and manipulated to contact testing elements while maintaining high quality cryogenic conditions. Thermal shielding is achieved by floating shields and/or flexible bellows that provide effective thermal shielding of the test environment while enabling manipulation of wafers with a wide range of motion. Also provided are novel door assemblies, chuck configurations, and vacuum plate bases that enable effective maintenance of cryogenic conditions and high throughput.Type: GrantFiled: November 19, 2020Date of Patent: March 12, 2024Assignee: High Precision Devices, Inc.Inventors: Michael Snow, Joshua West

Publication number: 20230108475Abstract: Improved heat sinking of electronic and/or photonic integrated circuit chips is provided by including thermal-only contacts on unused parts of the chip. The resulting chip can be bonded to a cold plate with a process that ensures that only the thermal contacts of the chip touch the cold plate, thereby avoiding problems caused by the cold plate creating electrical shorts of the chip. For example, the thermal contacts can be higher features than any electrical features on that side of the chip. This approach is expected to be especially useful for applications requiring low temperature operation (e.g., operation at 100K or less, preferably operation at 10 K or less).Type: ApplicationFiled: September 30, 2022Publication date: April 6, 2023Inventor: Michael Snow
