Embodiment Construction

[0040] Figure 1 to Figure 5 Different views of an embodiment of a sensor that have been manufactured by a method according to the disclosure are shown.

[0041] figure 1 A perspective view of the sensor 1 is shown. The housing 2 of the sensor 1 is formed from a rewiring substrate 3 and a sleeve 4 . In the upper region, a housing opening 5 is formed, into which an intermediate carrier 6 (also referred to as an interposer) is pressed. The intermediate carrier 6 has an intermediate carrier opening 7 through which a filling 8 is visible.

[0042] figure 2 A side view of a sensor 1 with a rewiring substrate 3 and a sleeve 4 is shown.

[0043] image 3 A top view of a sensor 1 with a rewiring substrate 3 , a sleeve 4 , an intermediate carrier 6 and a filling 8 is shown.

[0044] Figure 4 A perspective view showing a cross-section of the sensor 1 . An ASIC (Application Specific Integrated Circuit) 9 is arranged on the rewiring substrate 3 , and a sensing element 10 is arr...

Abstract

The present disclosure relates to a method for producing a sensor, the sensor having a sensing element and a housing, the housing having an interior which is accessible through a housing opening, and the sensing element is arranged in the interior and is designed to detect a property and / or a composition of an ambient medium of the sensor, the method comprises filling a protective medium into the interior through the housing opening, the protective medium being designed to transmit a property and / or a composition of an ambient medium to the sensor element, fixing a preferably flexible membrane to or in the housing opening, preferably for closing the housing opening, the protective medium being designed to transmit the property and / or the composition of the ambient medium to the sensor element, and the preferably flexible membrane being designed to transmit the property and / or the composition of the ambient medium to the sensor element. The diaphragm has at least one diaphragm opening and closes the at least one diaphragm opening. The present disclosure also relates to a sensor manufactured according to such a method.

Description

technical field [0001] The invention relates to a method for producing a sensor, wherein the sensor has a sensing element and a housing, wherein the housing has an interior space accessible through a housing opening, and wherein the sensing element is arranged in The properties and / or composition of the surrounding medium in the interior and designed to detect the sensor. [0002] The invention also relates to a sensor. Background technique [0003] Although the invention is generally applicable to any sensor by means of which the properties and / or composition of the surrounding medium can be detected, the disclosure is explained with reference to a pressure sensor. [0004] Pressure sensors have been widely used in consumer electronic appliances, such as smartphones and smart watches. Driven by new applications such as indoor navigation or fitness tracking, the requirements for measurement accuracy of pressure sensors continue to increase. At the same time, new device ge...
