Patent EP-0402188-A1 (EP)
Inventor: MUR REMY
IPC: H01L23/482
Filed: 1990-05-15
Abstract: This component (1) comprises a mesa (2) formed at the surface of a semiconductor substrate (3), the substrate corresponding to a first electrode and the peak of the mesa corresponding to a second electrode of the component. According to the invention, it comprises on one of its lateral regions a connection region comprising in its surface a wiring pad (11) formed on an insulating substrate (9) with a low dielectric constant, such as a glass, substituted for the semiconductor substrate (3) in this connection region, this wiring pad being connected by a narrow conductive link (12) to the surface (10) of the peak of the mesa in such a way as to connect these two elements electrically. The connection between the wiring pad (11) and the circuit in which the chip is connected can thus be carried out by a wire (17) having a diameter considerable greater than the diameter of the mesa, which allows this operation to be carried in an industrial manner by means of conventional transfer and connecting machines. <IMAGE>

IPC: G01C19/72
Filed: 1990-11-14
Abstract: The invention relates to a fibre optic measuring device of the type in which the change in a measured parameter generates a phase difference between two waves in a SAGNAC ring interferometer (2). Electronic means (7) comprise a processing system (9) delivering a signal depending on the measured parameter and electronic means (12) controlling the phase modulator (4). The electronic means (12) produce a control signal for the modulator determined in such a way that the phase difference  delta  PHI m which it produces between the counter-propagating waves periodically takes the following four successive values:   delta  PHI 1 =  PHI o  delta  PHI 3 = a PHI o delta  PHI 2 = -  PHI o  delta  PHI 4 = - a PHI o  where  PHI o is a constant phase shift and it depends on a, and a is a positive constant satisfying the condition: cos  PHI o=cos a PHI o. The gain of the channel for controlling the modulation is kept constant by producing a signal depending on the said gain by exploiting the four values x1, x2, x3, x4 delivered in response to a period of the modulation signal according to the expression (x1+x3)-(x2+x4), the said signal acting on the modulator in such a way as to keep the gain constant.
