Abstract
Invenţia se referă la tehnica semiconductorilor, în special la dispozitive semiconductoare cu capacitate variabilă.Dispozitivul semiconductor de tip varactor în baza diodei Schottky include un substrat semiconductor ce conţine o regiune structurată şi contacte ohmice. Noutatea dispozitivului constă în aceea că regiunea structurată este executată poroasă, cu porii orientaţi perpendicular suprafeţei, totodată raportul adâncimii regiunii poroase către distanţa dintre pori este mai mare de zece.Procedeul de confecţionare a dispozitivului semiconductor de tip varactor include decaparea substratului semiconductor şi depunerea contactului metalic de tip Schottky şi a contactelor ohmice. Noutatea procedeului constă în aceea că decaparea substratului se efectuează prin metoda electrochimică, iar depunerea contactului metalic de tip Schottky se efectuează prin aplicarea impulsurilor de tensiune în soluţie de electrolit.
