FIELD: process engineering.
SUBSTANCE: invention relates to electronics engineering and can be used to produce crystals of thermal transducers and thermometers. Proposed method comprises forming marks by diamond cutter on plate surface and separation by bending the plate. Note here that marks are formed on both sides of the plate. Marks arranged on plate side extended in separation, are formed to depth of 1.1 to 1.3 of coat thickness, while those on contracted side are formed to depth of 2.5 to 3.0 of coat thickness.
EFFECT: higher reliability and yield of ready crystals.
