In some other preferred embodiments, the upper surface of the flexible substrate is provided with an antenna, and the antenna is used for absorbing wireless radio frequency energy for power supply and transmitting signals in a bidirectional and interactive mode. The antenna is annularly distributed on the periphery of the flexible touch screen. The antenna comprises a plurality of concentric annular antennas with sequentially increased outer diameters.

In other preferred embodiments, the outer surface of the sucker is provided with a metal film for preventing electric, magnetic, wave and optical interference, and the metal film is positioned outside the acoustic sensor, the electric sensor, the optical sensor and the mechanical sensor.

In other preferred embodiments, a flexible touch screen is arranged above the flexible film antenna layer and used for selecting a working model of the stethoscope, interacting man-machine and displaying information data.

The MEMS acousto-electric conversion array chip can realize ultra-wideband audio acquisition, can better acquire more subtle abnormal noise of the lung, simultaneously captures the dynamic motion state of the heart by adopting the Doppler principle, and is also provided with a secondary echo acquisition system. Different from the theory of operation of ordinary stethoscope mechanical type sound collection and conveying, wireless intelligent electron stethoscope adopts MEMS acoustoelectric conversion array chip, not only can widen acquisition frequency, high frequency sound wave and low frequency sound wave that ordinary stethoscope can not gather, but also the Doppler chip of array orientation location has been adopted, the motion state of accurate seizure heart to provide the basis of accurate measurement rhythm of the heart and blood pressure, can provide effectual pathology basis for the heart disease patient simultaneously.

The passive photoelectric detection sensing chip adopts an MEMS infrared energy spectrum catcher; the passive photoelectric detection sensing chip detects the body temperature of a human body by absorbing infrared wavelength emitted by the human body; the active photoelectric detection sensor chip adopts a photoelectric conversion sensor chip.

Working principle of the optical sensor: high-sensitivity photodiodes and four types of red, yellow, blue and green LED frequency scanning light-emitting diodes (with different wavelengths of 50-980nm emission). Optically isolated from the emitter by an opaque optical baffle. The working principle is that light is irradiated into the skin, blood and surrounding tissue will absorb different amounts of light, respectively, and the non-absorbed light is reflected back to the detector. By using the measured values of the absorption amount measured at different wavelengths, the physiological characteristic parameters such as pulse rate and blood oxygen saturation can be determined. For example: the blood oxygen saturation is calculated from the different absorbances of blood for red light (660nm) and infrared light (940 nm). The quality of the measurement depends strongly on the achievable signal-to-noise ratio and the linearity of the photodetector.

The optical sensor is born by a photoelectric conversion sensor chip (similar to SFH7060), blood oxygen saturation, heart rate and blood pressure are calculated by modeling transmission and reflectivity of energy spectrums with different frequencies and different wavelengths (such as red light, yellow light, blue light and green light) after a human body is subjected to frequency scanning (the wavelength is 50-980 nm) according to a correlation law, and the optical sensor is used as an acoustic method to provide auxiliary reference so as to improve the accuracy of the blood pressure and the heart rate.

The super stethoscope can be prepared by adopting an MEMS + IC wafer-level three-dimensional integrated manufacturing method, and comprises the following steps:

1. IC design, MEMS, IC process flow sheet, wafer-level MEMS + IC system three-dimensional integration, chip-level integrated system assembly and device flexible packaging.

2. And (5) developing and debugging software.

3. And (5) product inspection.

The process flow of the wafer-level three-dimensional integrated manufacturing is as follows:

firstly, preparing a chip inner through hole with the diameter of 1-3 mu m on a device wafer which is finished with a manufacturing process and tested by using a dry etching (DRIE) process, passivating the through hole, then manufacturing a multi-level dielectric layer, and then finishing deep silicon grooving etching. High conformal CVD deposition O for lateral via isolation₃TEOS-oxide layer, the metallization of the through holes inside the chip is to deposit a tungsten metal layer by MOCVD (MOCVD-TiN is used as a barrier layer), and the metal plugs are formed by etching the back surface. The lateral electrical connection of the tungsten filled chip internal via and the device topmost metal layer is formed using standard aluminum metallization processes.

After these process steps are completed, the devices are wafer level tested and selected. The final step performed on the top wafer of standard thickness is full mask copper plating. And then temporarily adhering the uppermost wafer to a processing wafer, and then carrying out highly uniform thinning processing on the uppermost wafer by using high-precision grinding, wet chemical spin-coating etching and a final chemical mechanical planarization processing technology until the tungsten filling through hole is exposed from the back. In order to deposit a dielectric layer for electrical isolation and to enable connection to tungsten filled chip internal vias, copper/tin electroplating techniques are used that penetrate the resist mask. Thus its surface is completely covered by the solder metal material, the isolation trenches are used to form electrical contacts in the copper/tin layer, and the remaining areas not used for electrical connection can be used as simulation zones for future stack mechanical balancing. Finally, copper is used as the material of the solder metal system to perform the plating treatment of the lowest wafer through the resist mask.

After singulation, the selected good chips are matched to the substrate being processed and placed on the lowest wafer using a chip-wafer bonding apparatus with high efficiency and high alignment accuracy (10 μm). Both mechanical bonding and electrical contacting of the transfer chip are achieved in a one-step process using solid-liquid interdiffusion (SLID) bonding techniques.

During the bonding process, when pressure is applied when the temperature reaches 300 ℃, liquid tin interdiffuses with copper, and finally an intermetallic compound (IMC) Cu3Sn is formed. The epsilon phase formed is thermodynamically stable and has a melting point above 600 ℃. With the proper film thickness, the tin is consumed and solidifies completely within a few minutes, leaving copper on both sides.

And finally, realizing the integration of the planes and 3D of various sub-chips (namely an acoustic sensor, an electric sensor, a light sensor, a mechanical sensor and a controller which are arranged on a flexible substrate) on the wafer by utilizing the aluminum wiring to interconnect the tungsten-filled ICV and the metallization layer of the uppermost device and to interconnect the CuSn metal system and the metallization layer of the lowermost device, thereby finishing the wafer-level three-dimensional manufacturing of the mother chip.

The method adopts a wafer-level three-dimensional integration technology to modularize and integrate the sub-chips prepared by different basic processes such as MEMS and CMOS in the chip again to form a multifunctional mother chip, thereby realizing the optimal organic combination of the chips adopting special different basic processes, namely, an acoustic sensor, an electric sensor, an optical sensor, a mechanical sensor and a controller can simultaneously flow in parallel on a plurality of IC process lines, and then the flowing sub-chips (bare chips) are integrated through the wafer-level three-dimensional integration manufacturing technology to form a composite mother chip with various functions. The design and layout of the functional devices of the mother chip are determined according to the specific performance of the functional daughter chip, and the overall design and wiring still follow the basic concept of IC design.
