With PRD involved, CTE values were obviously reduced from 42 ppm K −1 to −2.53 ppm K −1 in the temperature range of 50–400 °C. Especially, PIb-5 had the ultralow CTE of 0.55 ppm K −1, which was close to the value of silicon wafer (Fig. 2b).

The linear thermal expansion coefficient (CTE) is dependent on the material from which an object is made. Generally, linear thermal expansion is most applicable to solids. The CTE employs reciprocal temperature units (K -1 , °F -1 , °C -1 , etc.) representing the length change per degree per unit length, e.g., in./in./°F or mm/mm/°C. Because CTE values are usually very small, it is common to express the expansion as ‘part per million’, i.e. ppm.

The measurement of CTE occurs over a temperature range so the ‘ppm’ of expansion must be converted to a ‘ppm/T’ value where T is the temperature unit.

The current reference is generated by the division of a temperature-independent voltage and resistance in a simple way. The low temperature-independent voltage is generated based on the threshold voltage difference between two same-type NMOS transistors See PPM C 300 for completing a form STD. 607.

CTE vs. VaR Without getting into the mathematics of coher-ence, a simple picture can show the appeal of CTE as opposed to VaR. CTE is defined as the probability weighted loss above a certain prob-ability level, while VaR is the loss at a certain probability level. One definition of CTE is that it is the average of all VaR values for probabili- High Precision Foil Resistor with TCR of ± 2.0 ppm/°C, Tolerance of ± 0.005 % and Load Life Stability of ± 0.005 % RCK Series Vishay Foil Resistors Document Number: 63214 For any questions, contact: foil@vishaypg.com www.vishayfoilresistors.com Revision: 13-Jun-11 1 INTRODUCTION.
