In this work we report recent theoretical calculations of a superconducting island in a strong 
 vortex confinement regime. The obtained results reveal the evolution of superconducting condensate 
 as a function of electron mean-free path (l) with the evolution of an applied magnetic field H0. The 
 results of this study provide an insight about the emergent superconducting properties under such 
 conditions, using the Ginzburg-Landau numerical simulations where spatial variation of thickness d 
 on island, omnipresent in these kind of structures grown on Si (111), is taken into account. These 
 results offer a new route to tailor superconducting circuits by using the controlled bombardment, in
 order to explore the impact on vortex distribution, phase of order parameter, number of vortices, free 
 energy and the first H1 and second critical field H2.
