Problems solved by technology

The commonly used stainless steel metal mask plate will have a large deformation at this time, which makes the shielding protection of the surface electrode poor and short circuit occurs
Generally, to solve the deformation of the metal mask plate during the evaporation process, complex tooling is used to compress and fix the mask plate, but this kind of tooling is more difficult and not suitable for mass production of substrates

Abstract

The invention discloses a masking tool for evaporation of electrodes of a micro-mechanical quartz sensor. The masking tool comprises an upper masking plate (10), a lower masking plate (30) and fixing fixtures (40), wherein the upper masking plate (10) comprises a first frame (1) and a first sheet (3); the lower masking plate (30) comprises a second frame (5) and a second sheet (8); the second sheet (8) is fixed on the upper surface of the second frame (5) through laser welding; air suction holes (4) are transversely formed in the second frame (5); air suction grooves (7) are formed in positions, which are close to the outer edge of the second sheet (8), of the second frame (5) circumferentially and communicated with the air suction holes (4); and the upper masking plate (10), a to-be-machined substrate (20) and the lower masking plate (30) are sequentially fixed through the fixing fixtures (40). The masking tool is simple in structure, convenient to machine and capable of well realizing two-sided masking evaporation of the electrodes.

Description

technical field [0001] The invention relates to a mask tooling used for vapor deposition of quartz micromechanical sensor electrodes. Background technique [0002] Micromechanical sensor is a new type of sensor manufactured by microelectronics and micromachining technology. Compared with traditional sensors, it has small size, light weight, low cost, low power consumption, high reliability, and is suitable for mass production. It is easy to integrate and realize the characteristics of intelligence. At the same time, the feature size on the order of micron makes it possible to complete some functions that cannot be realized by traditional mechanical sensors. Quartz crystals are widely used in the preparation of micromechanical sensors due to their advantages such as good insulation, good temperature stability, good mechanical properties, high quality factor, and easy fabrication and processing. Such as quartz micromachined gyroscope, quartz micromachined accelerometer, micr...
