Study of Certified Reference Material Preparation Technique for Microelectronic Digital Circuits
نویسندگان
چکیده
− This paper introduces an alternative method to traditional certified reference material (CRM) preparation technique for microelectronic digital circuits. Instead of selfmanufacturing chips, a novel preparation technique is introduced which selects matured samples as the CRMs, these samples are also called certified reference samples (CRSs). The use of CRS not only greatly reduces the difficulties of preparation, but also brings microelectronic CRM preparation technique to a new domain. Finally, the preparation contents and methods, the preparation processes, as well as the maintenance, preservation and usage of the CRS are discussed in detail in this paper.

Elimination of Chemical and Spectral Interferences in Measurement of Trace Elements in Urine and Blood by Combined Electrodeposition-Electrothermal Atomic Absorption Spectrometry
A combined electrodeposition-ETAAS technique has been applied to the analysis of Pb, Cd, Co, Ni, Cr and Mn in biological samples in order to overcome interferences and to minimize sample pretreatment. It requires minimal sample preparation with the electrolysis process aiding partial decomposition of the organic matrix, adequate for the release and deposition of trace elements. In an initia...
متن کاملComparison of four digital PCR platforms for accurate quantification of DNA copy number of a certified plasmid DNA reference material
Digital polymerase chain reaction (dPCR) is a unique approach to measurement of the absolute copy number of target DNA without using external standards. However, the comparability of different dPCR platforms with respect to measurement of DNA copy number must be addressed before dPCR can be classified fundamentally as an absolute quantification technique. The comparability of four dPCR platform...

The paper describes the preparation and production of the reference materials, IRMM-1000a and IRMM-1000b, certified for the production date based on the 230Th/234U radiochronometer in compliance with ISO Guide 34:2009. The production date of the reference materials corresponds to the last separation of 230Th from 234U, i.e. when the initial daughter nuclide content in the material was finally r...

In this paper we implement a simple DC model for CNTFETs already proposed by us in order to carry out static analysis of basic digital circuits. To verify the validity of the obtained results, they are compared with those of Wong model, resulting in good agreement, but obtaining a lighter ensuring compile and shorter execution time, which are the main character...
