This kind of reduced algebra is essential background for the mathematics of computer science, coding theory, primality testing, and much more. In this paper we propose a unique approach for calculating “mod” operation, regardless of the signs of operands by which all ambiguities present in high level languages, such as C, Java, C++, Mathematica, Matlab, are overcome. Modular arithmetic is quite a useful tool in number theory. In particular, it can be used to obtain information about the solutions (or lack thereof) of a specific equation. In order to reduce the number of iteration steps during the calculation of g.c.d. and solving linear diophantine equations in two variables, based on Euclidian and extended Euclidian algorithm, we propose the usage of mod and mod operations.","PeriodicalId":396356,"journal":{"name":"2012 28th International Conference on Microelectronics Proceedings","volume":"9 2","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2012-05-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"120910439","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The PA spectra were measured in a frequency range (from 20 to 20000 Hz), for different thicknesses of Si rectangular membranes (from 10 to 100 μm).. The elastic characteristics of the Si chip with square membranes were described by the theory of thin elastic plate, i.e. as an elastic simply supported rectangular plate. The PA signals (sum of the thermodiffusion, thermoelastic and electronic deformation components) were calculated and compared with the experimental ones. These results showed that the PA elastic bending spectra are convenient for investigation the characteristics of micromechanical membraines. The PA elastic bending spectra of the optically driven micro-opto-electro-mechanical systems (MOEMS) enable, for example, to investigate the different electronic and thermal transport characteristics or technological processes in MEMS fabrications, etc.","PeriodicalId":396356,"journal":{"name":"2012 28th International Conference on Microelectronics Proceedings","volume":"25 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2012-05-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125111423","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

First of all, we check the gate oxide area in EEPROM cell on the supposition that inner cell's and outer cell's gate oxide thickness are different. After we checked it, we found that the most effective reason of the characteristics changes was Gate Oxide Thickness changes had a decisive effect on the EEPROM Cell' changes according to the degree of STI profile(Top Corner Rounding).

By applying a numerical computational method we determined the pressure dependence of the equilibrium coverage of the semiconductor surface by chemisorbed gas particles. We concluded that the pressure dependence of the total coverage of the surface by adparticles, and also of coverages by both the neutral and ionized adparticles, can be obtained by measuring the adsorbed mass. We propose the use of nanocantilever sensors for such extremely sensitive mass measurements. The obtained adsorption induced cantilever's resonant frequency shifts are higher than the detection threshold set by the termomechanical noise. This confirms the applicability of the used nanocantilever sensor for experimental characterization of AD processes at semiconductor surfaces.","PeriodicalId":396356,"journal":{"name":"2012 28th International Conference on Microelectronics Proceedings","volume":"75 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2012-05-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129993999","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
