Abstract
Inventia se refera la un procedeu de recuperare a elementelor componente ale dispozitivelor semiconductoare, care prezinta defectiuni electrice sau mecanice, într-una din etapele procesului de fabricatie. Procedeul de recuperare, conform inventiei,consta în dizolvarea preliminara a rasinii pasivante, examinarea vizuala a structurii de siliciu descoperite si, în caz ca acesta nu prezinta fisuri, iar conexiunile sunt bine lipite, decaparea si repasivarea structurii de siliciu, în scopul obtinerii unui dispozitiv bun din punct de vedere electric, iar în caz ca structura prezinta fisuri, dizolvarea acesteia într-o solutie de hidroxid de sodiu sau potasiu si apoi a aliajelor de lipire, pe baza de plumb într-un amestec de acid acetic glacial si apa oxigenata pentru obtinerea în final, dupa o splare si uscare în acetona, a conexiunilor precum si a ambazei ce pot fi utilizate pentru montarea altor dispozitive semiconductoare.
