摘要： A force sensing element is provided with a gauge portion and a plurality of electrodes. The gauge portion is formed of an n-type semiconductor substrate whose (100)-face serves as a main face, a p-type semiconductor substrate whose (110)-face serves as a main face, or a p-type semiconductor substrate whose (111)-face serves as a main face, and is pressed in a thickness direction of the semiconductor substrate upon receiving a force. The electrodes are electrically connected to the gauge portion such that a current path extending in a direction corresponding to the thickness direction of the semiconductor substrate is formed in the gauge portion. The force sensing element thus constructed makes it possible to detect a force with high precision.

摘要： A pressure sensor has a housing having a first block and a second block provided therein. A force to be measured applies upon a upper face of the first block. An upper face of the second block makes contact with a base face of the first block. Piezoresistive elements are formed within the base face of the first block. The resistance values of these piezoresistive elements change as contacting pressure between the first block and the second block changes. A first electrode is formed on an upper face of the first block. A second electrode is formed on a base face of the second block. Electrical characteristics between the first electrode and the second electrode change following change in the contacting pressure between the first block and the second block.

For example, a force detection block 120 may include a semiconductor substrate 122, a first insulating layer 124 and a semiconductor layer 126 (strain gage). The strain gage 126 preferably includes a site where resistance changes in accordance with the stress acting thereon. The strain gage 126 preferably constitutes at least a portion of a ridge 130 projects from the surface of the force detection block 120. A force transmission block 138 may be attached to a top surface of the ridge 130. The width of the first insulating layer 124 is preferably greater than the width of the semiconductor layer 126.
