Abstract:
1. A thin plate-shaped six-axis force sensor chip comprising a semiconductor substrate formed by semiconductor film-forming processes, the sensor chip having through-holes formed therein and arranged so that the sensor chip is functionally divided by the through-holes into an action part to which an external force is applied, a support part to be fixed to an external structure, and a plurality of connecting parts each connecting together the action part and the support part and having a bridge portion joined to the action part and an elastic portion joined to the support part, wherein each of the connecting parts has a plurality of strain resistance devices each comprising an active layer formed on at least one of front and rear faces thereof in an area thereof where deformation strain effectively occurs, the strain resistance devices being electrically connected to corresponding electrodes disposed in the support part, and wherein the connecting parts each have a generally T-shaped configuration.
