Although the effects of u.v. radiation on poly(methyl methacrylate) and poly(methyl acrylate) are superficially different, nevertheless there are obvious fundamental similarities and this copolymer system was chosen for study in order to observe the influence of one type of chain unit on the degradation reactions of the other. Rates of chain scission and crosslinking were measured at room tempe...

This work presents the performance degradation of a 32-bit DSP fabricated with 28 nm FDSOI technology subjected to different levels gamma radiation. A new mixed hardening methodology based on electrical compensation and thermal regeneration is applied irradiated devices recover degraded characteristics induced by total ionizing dose. The application this seeks extend lifetime integrated circuit...

In this work naphtha is exposed to ultraviolet rays under various conditions namely; UV exposureonly, exposure with cooling, cooling and catalyst, Cooling,Catalyst Oxidant O2 Catalyst investigate the bondscracking process (Photo-degradation or photolysis reactions) its effect on octane numberwhere several bonds are be broken due absorption high energy of radiation. It expectedthat number should...

In these last years several works have been devoted to study the radiation effect in CMOS components with ultrathin gate oxide, showing that different types of leakage current can be produced by high-energy ionizing radiation. Radiation Induced Leakage Current (RILC) [1-2], Radiation Soft Breakdown (RSB) [3-5], and Single Event Gate Rupture (SEGR) [6] represent the most important degradation ph...

In this work, radiation induced damage mechanisms in deep submicron technology is resolved using finger gated-diodes (FGDs) as a radiation sensitive tool. It is found that these structures are simple yet efficient structures to resolve radiation induced damage in advanced CMOS processes. The degradation of the CMOS image sensors in deep-submicron technology due to c-ray irradiation is studied b...
