Abstract

The total ionizing dose (TID) responses of

$0.35~\mu $

m and

$0.13~\mu $

m SiGe HBTs at liquid-nitrogen temperature (78 K) were investigated using 10 keV X-rays. For the first time, we compared the annealing behaviors of SiGe HBTs irradiated at 78 K and room temperature (297 K). The results reconfirm that SiGe HBTs have superior TID tolerance up to Mrad(Si) levels, and the current gain degradation of DUTs irradiated at 78 K is much less than those irradiated at 297 K. However, the

$0.35~\mu $

m SiGe HBTs irradiated at 78 K show further degradation after room temperature annealing (RTA) due to the thermal activation of oxide charge migration and the long-term buildup of interface traps. The

$0.13~\mu $

m SiGe HBTs irradiated at 78 K show minor change after RTA, which can be attributed to the competition between interface trap creation and annealing.

期刊介绍： The scope of the publication includes, but is not limited to Reliability of: Devices, Materials, Processes, Interfaces, Integrated Microsystems (including MEMS & Sensors), Transistors, Technology (CMOS, BiCMOS, etc.), Integrated Circuits (IC, SSI, MSI, LSI, ULSI, ELSI, etc.), Thin Film Transistor Applications. The measurement and understanding of the reliability of such entities at each phase, from the concept stage through research and development and into manufacturing scale-up, provides the overall database on the reliability of the devices, materials, processes, package and other necessities for the successful introduction of a product to market. This reliability database is the foundation for a quality product, which meets customer expectation. A product so developed has high reliability. High quality will be achieved because product weaknesses will have been found (root cause analysis) and designed out of the final product. This process of ever increasing reliability and quality will result in a superior product. In the end, reliability and quality are not one thing; but in a sense everything, which can be or has to be done to guarantee that the product successfully performs in the field under customer conditions. Our goal is to capture these advances. An additional objective is to focus cross fertilized communication in the state of the art of reliability of electronic materials and devices and provide fundamental understanding of basic phenomena that affect reliability. In addition, the publication is a forum for interdisciplinary studies on reliability. An overall goal is to provide leading edge/state of the art information, which is critically relevant to the creation of reliable products.
