Abstract

Inventia se refera la domeniul tehnologiei planare de obtinere a straturilor semiconductoare de tip A4B6, in special la un procedeu de obtinere a substratului de BaF2 cu suprafata perfecta. Procedeul include detasarea sau taierea substratului initial de-a lungul directiilor cristalografice alese, slefuirea chimico-mecanica a suprafetei, recoacerea in vid a substratului la temperatura de 973°K, timp de 30 min, apoi depunerea unui strat suplimentar de BaF2 in vid suprainalt la temperatura substratului de 1023°K, timp de 3…5 min, cu controlul neintrerupt al calitatii suprafetei prin metoda difractiei electronilor rapizi. Revendicari: 1 Figuri:The invention relates to the field of planar technology for obtaining the A4B6 type semiconductor layers, in particular to a process for obtaining the BaF2 substrate with perfect surface. The process includes detachment or cutting of the initial substrate along the chosen crystallographic directions, the chemical-mechanical grinding of the surface, the annealing of the substrate in vacuum at 973 ° K, for 30 minutes, and then depositing an additional layer of BaF2 in the super vacuum at substrate temperature of 1023 ° K, for 3 ... 5 min, with uninterrupted control of surface quality by the fast electron diffraction method.
