Abstract

Prezenta inventie se refra la un procedeu de realizare a magnetodiodelor planare cu siliciu, ce pot fi utilizate în aparatura de masura si control a cîmpului magnetic ca si la obtinerea unor contacte nemecanice de fiabilitate foarte mare la motoare electrice. Procedeul, conform inventiei, în scopul obtinerii unei sensibilitati, mari în cîmp magnetic, prevede oxidarea initiala la temperatura joasa în atmosfera oxidanta cu vapori de tricloretilena, implantare ionica pentru realizarea zonelor de plusare cu evitarea contaminarii din sursa lor de bor, difuzie de fosfor în mediu oxidant cu tricloretilena pentru conservarea timpuliu de viata în volum si scaderea vitezei de recombinare la suprafata, lepuirea grosiera pe spatele plachetei pentru cr esterea vitezei de recombinare a purtatorilor, în aceasta zona, realizarea contactelor de anod si catod pe aceeasi suprafata, precum si realizarea unui inel de garda în scopul scaderii efectelor de margine (strapungeri parazite).The present invention relates to a process for making planar silicon magnetodiodes, which can be used in the field of measurement and control of the magnetic field, as well as to obtain non-mechanical contacts of high reliability in electric motors. The process according to the invention in order to obtain a high sensitivity in the magnetic field provides for initial oxidation at low temperature in the oxidative atmosphere with trichlorethylene vapors, ionic implantation for the realization of the rebound zones with avoidance of contamination from their boron source, phosphorus diffusion in the oxidation medium with trichlorethylene for preserving the lifetime in volume and decreasing the recombination velocity at the surface, the coat thickness on the back of the plate for the speed of recombination of the wearers in this area, the realization of the anode and cathode contacts on the same surface as well as the realization a guard ring to reduce edge effects (parasitic straps).
