Description

В известных непроволочных сопротивлени х провод щий слой получен методом термической возгонки в вакууме токопровод щего материала , но :возгон емый материал обладает сравнительно малой величиной удельного объемного сопротивлени .In the known non-wire resistances, the conductive layer is obtained by thermal sublimation of a conductive material in vacuum, but: the sublimated material has a relatively small volume resistivity.

Дл  получени  сопротивлени  большей величины приходитс  использовать высокоомные провод щие пленки чрезвычайно малой толщины , пор дка дес тых и сотых долей микрона.To obtain a larger resistance, high resistance ohmic conductive films of extremely small thickness, in the order of tenths and hundredths of microns, must be used.

Такие пленки недостаточно стабильны к внешним воздействи м, а однородность их зависит от свойств поверхности изол тора, на которую они нанос тс .Such films are not sufficiently stable to external influences, and their homogeneity depends on the properties of the surface of the insulator to which they are applied.

Предлагаетс  в качестве возгон емого материала дл  провод щего сло  примен ть порощкообразную смесь из металлического сплава и непровод щих окислов.It is proposed to use a powder-like mixture of a metal alloy and non-conductive oxides as a sublimated material for the conductive layer.

Из указанной смеси можно получать пленки с удельным объемным сопротивлением, во много раз большим , чем у пленок, полученных таким же методом, но при возгонке только одного провод щего металлического сплава.From this mixture, one can obtain films with a specific volume resistance, many times larger than those of films obtained by the same method, but with sublimation of only one conducting metal alloy.

Одновременно при возгонке обеспечиваетс  высока  степень дисперсности испар емых материалов и однородность структуры пленки.At the same time, during the sublimation, a high degree of dispersion of the evaporated materials and a uniform film structure are provided.

Величина сопротивлени  регулируетс  составом смеси и толщиной пленки.The magnitude of the resistance is controlled by the composition of the mixture and the thickness of the film.

К числу непровод щих или плохо провод щих окислов, которые пригодны дл  испарени  в смеси с тем или иным металлическим сплавом, могут быть отнесены двуокиси кремни  и титана, окиси алюмини , хрома , железа, кадми , никел , кобальта , олова.Nonconductive or poorly conductive oxides, which are suitable for evaporation in a mixture with one or another metal alloy, can include silica and titanium dioxide, aluminum oxide, chromium, iron, cadmium, nickel, cobalt, tin.

В зависимости от химических и электрических свойств примен емого металлического сплава и температуры его возгонки, выбираютс  те или иные окислы или их смесь.Depending on the chemical and electrical properties of the metal alloy used and the temperature of its sublimation, one or other oxides or their mixtures are selected.

Качественное соотношение меледу наход щимис  в смеси окислами и металлическими сплавами определ ет зависимость сопротивлени  пленки от температуры.The qualitative ratio of meleds in a mixture of oxides and metal alloys determines the dependence of film resistance on temperature.
