| 91 | Measurement System Validation Procedure for High Pressure Gas Flow Calibration System–Comparison Method/Circulating Flow | This document describes the uncertainty evaluation procedure for high-pressure air flow calibration system - comparison method / circulating flow at the National Measurement Laboratory (NML). (system code F05) The working standard units are eight 2-inch rotary meters and two 6-inch ultrasonic flowmeters. The mass flow rate of the standard unit is directly calculated by measuring the temperature, pressure and actual volume flow rate of the standard unit. Divide the mass flow rate of the standard unit by error correction factor to obtain the passing standard mass flow rate. It is also possible to convert the standard mass flow rate of the standard unit to the actual state (or reference state) of the under-calibrated flowmeter, and then compare the actual (or reference) volume flow rate between the standard unit and the under-calibrated flowmeter. The uncertainty analysis is according to ISO/IEC Guide 98-3:2008(GUM). The considered uncertainty categories that affect the calibration results are estimated through either Type A or Type B evaluation. The combined standard uncertainty of the measurement result is then obtained by taking the root-sum-squared (RSS) of each uncertainty component multiplied by its sensitivity coefficient. The expanded uncertainty is obtained by multiplying the combined standard uncertainty with the coverage factor at the 95 ％ confidence level, which is obtained based on the effective degrees of freedom calculated by Welch-Satterthwaite equation. The calibration capability of this facility is shown as below: Working fluid：Dry air； Pressure：(500 to 5500) kPa (absolute)； Temperature：ambient temperature； Actual volume flowrate：(25 to 2000) m3/h； Standard volume flowrate：(125 to 110000) m3/h ＠ (101.325 kPa , 23 ℃)； Mass flowrate：(150 to 132000) kg/h； Cumulative total volume：( 1.25 to 166.67) m3 ＠ (25 to 2000) m3/h。 According to the operation mode and the system measurand, the relative expanded uncertainty and coverage factor with a known effective degree of freedom based upon a confidence level of approximately 95 ％ are summarized as follows.

As a result, the overall number of physical meetings remained low by 50. In the past, TC meetings and seminars held in person were still held online, and the dates decided by each TC were completed before the General Meeting. The meetings including the APMP 2022 Executive Committee meeting (EC meeting), EC-CC meeting, General Assembly (GA) and technical seminar were attended by Wei-En Fu (Executive Committee Member) to represent CMS/ITRI and NML. At the same time, he was invited by the APMP Chair to host the 2022 NMI Director Workshop. By attending Executive Committee meetings, Executive Committee and Technical Chairman Meetings and General Assembly, major APMP highest decision-making strategy and direction can be understood and participated in the first-hand, and interactions with the other Executive Committee members from other economies in the APMP region can be enhanced and to established with good relationships and future international cooperation opportunities. One of the tasks assigned to EC is to participate in the Clean Water Focus Group workshop to understand its development plan. |

| 96 | Substrate X-ray techonology Ultra-thin film measurement | This paper developes substrate assisted X-ray leakage techonology which is used in measuring the ultra-thin film on substrate. The basic ideal is to use X-ray exciting the substrate and measure the leakage X-ray from ultra-thin film. The intensity of leakage X-ray depend on the thickness of ultra-thin film, measuring the small angle (from 0 to 2 degree) signal will reduce noise interference and improve signal sensitivity. Since the fluorescent intensity generated by the substrate is sufficiently high, it helps to reduce measurement time and improve measurement accuracy. This paper simulates HfO2, TiN, and TaN films with different thicknesses on silicon substrates. From the simulation results, it can be seen that the intensity curves with film thicknesses between 0.2 nm and 1.5 nm have the largest difference. This performance show that our work is suitable for the measurement of ultra-thin films, and has the potential to be applied to the on-line measurement of semiconductor film thickness in the future. |
