Abstract
An arrangement for reducing piezo-electric effects in piezo-electric effect sensitive electrical components formed in a semiconductor body is disclosed. The piezo-electric effect sensitive component or components are located in a particular zone of the semiconductor body. The semiconductor body is in general mounted on a support. However, the zone of the semiconductor body containing the piezo-electric sensitive component or components is not attached to the support but instead is separated from the support by a space. The presence of the space results in a certain degree of mechanical isolation of the part of the semiconductor body which contains the piezo-electric effect sensitive components, whereby the negative influence of the piezo-electric effect on the long term stability of an instrument utilizing the semiconductor body is reduced.
