In this work the role of the Si substrate in the high energy boron implantation damage recovering is studied. The boron implants were carried out in Czochralski grown (1 0 0) polished Si substrates as well as in epitaxial Si layers grown on (1 0 0) S

In this article the phenomenology related to the mechanisms of defect generation in Shallow Trench Isolation (STI) processes is discussed, and the role of the structure pattern is investigated. Defect formation is studied by plan and cross TEM analys

One of the most critical issues of the STI process is the reduction of the stress generation during the oxidation steps. This stress can create defects later on in the process, leading to increased leakage. In this work microscopy analyses confirm th

In this paper, the paper addressed the problem of estimating the risk of crystal defect generation in a complex device process. The validity of numerical calculations of the mechanical stress developed in the device process flow is assessed by compar

In this work the leakage current of junctions with a self-aligned cobalt silicide is studied. It is shown that junctions with a self-aligned CoSi2 layer show a leakage current excess which is strongly reduced by increasing the PAI energy. This indica

In this work. we address the problem of identifying the minimum temperature required to diffuse copper deposited at the silicon surface into the bulk. and to identify a suitable method to detect the initial stages of copper electrical activity at waf

In this paper, the correlation between dislocation density and transistor leakage current is demonstrated. The stress evolution and the generation of defects are studied as a function of the process step, and experimental evidence is given of the rol

A newly developed technique for the simultaneous measurement of the oxide–silicon interface properties and of minority carrier lifetime in the silicon volume was used for a systematic study of the nitridation process of oxide films.This technique i

Various substrates are compared for both bulk defect formation and thin oxide reliability. Wafers were subjected to a complete device fabrication process, and the formation of the denuded zone was monitored by SPV measurements of carrier lifetime. Ox

In this paper we present a systematic comparison among the most common methods (surface photovoltage, Elymat and microwave-detected photoconductive decay) for lifetime measurements. The possibility to identify contaminants and to quantitatively evalu
