Abstract: A pressure sensor using the MEMS element and the manufacture method thereof utilize the semiconductor processes to form the micro channel connecting to the chamber, open the micro channel, coat the anti-sticking layer on the inner surface of the chamber, and then seal the micro channel to keep the chamber airtight. Therefore, the manufacture method may essentially simplify the process to coat the anti-sticking layer on the inner surface of the airtight chamber to prevent the sticking and failing of the movable MEMS element.

Abstract: A force sensor comprises a first substrate, a second substrate, a third substrate, and a package body. The first substrate includes a fixed electrode, at least one first conductive contact, and at least one second conductive contact. The second substrate is disposed on the first substrate and electrically connected to the first conductive contact of the first substrate. The second substrate includes a micro-electro-mechanical system (MEMS) element corresponding to the fixed electrode. The third substrate is disposed on the second substrate and includes a pillar connected to the MEMS element. The package body covers the third substrate. The foregoing force sensor has better reliability.

Abstract: A three-axis accelerometer measures acceleration in three axes by a single movable mass block, so that a more compact design of the three-axis accelerometer can be achieved. In addition, a plurality of detection capacitors, which forms differential capacitor pairs, are arranged in symmetric configuration with respect to a rotation axis of the movable mass block for sensing functions. Therefore, during sensing motion of a target axis direction, the all other unwanted capacitance changes in other axis direction may be cancelled.

In addition, a plurality of detection capacitors, which forms differential capacitor pairs, are arranged in symmetric configuration with respect to a rotation axis of the movable mass element. Therefore, when the movable mass element rotates, the differential capacitance value is zero, and the detection error caused by rotation of the movable mass element can be avoided.

Abstract: A method for manufacturing a MEMS device includes disposing at least one bonding portion having a smaller bonding area in a region where an airtight chamber will be formed, and disposing a metal getter on a bonding surface of the bonding portion. According to this structure, when substrates are bonded to define the airtight chamber, the metal getter is squeezed out of the bonding position due to the larger bonding pressure of the bonding portion with a smaller bonding area. Then, the metal getter is activated to absorb the moisture in the airtight chamber. According to the above process, no additional procedure is needed to remove the moisture in the airtight chamber. A MEMS device manufactured by the above manufacturing method is also disclosed.

Abstract: A pressure sensor using the MEMS device comprises an airtight ring surrounding a chamber defined by the first substrate and the second substrate. The airtight ring extends from the upper surface of the second substrate to the interface between the first substrate and the second substrate and further breaks out the interface. The pressure sensor utilizes the airtight ring to retain the airtightness of the chamber.
