Abstract

PURPOSE:To measure the pressure sensitivity by using an electrode that is formed at the surface by placing a wafer on a wafer stage, thereby sucking a diaphragm under vacuum from the rear of a semiconductor pressure sensor by utilizing holes mounted at a wafer stage. CONSTITUTION:An electrical measurement is carried out from the surface of a semiconductor pressure sensor 1 and a pressure is applied from the rear of the semiconductor pressure sensor 1, so that the pressure sensitivity of the sensor 1 is measured in a wafer process. Thus, when the wafer 5 is placed on a wafer stage 2 and recessed parts 15 that are prepared at the rear side of the semiconductor sensor 1 are sucked under vacuum by utilizing through holes 3, a negative pressure equivalent to a stage of pressure that is applied from the surface to the recessed parts 15 of the semiconductor pressure sensor 1 is developed. Then a diaphragm 16 is deformed in the same manner that is deformed in the case where the pressure is applied from the surface side, so that is state of diaphragm makes it possible to measure the pressure sensitivity.

<Prior art> Semiconductor pressure sensors were developed based on the fact that when mechanical stress is applied to a semiconductor crystal such as silicon, the resistance changes significantly due to the piezoresistance effect. A strain gauge resistor is diffused and formed on the surface layer of the single crystal, a Wheatstone bridge is assembled with these four strain gauge resistors, and a recess is formed on the back surface of the silicon single crystal.
The thin part is the diaphragm, and electrodes are placed at appropriate locations on the surface. When pressure is applied to the semiconductor pressure sensor, the diaphragm deforms and the resistance value of the strain gauge resistor changes significantly due to the piezoresistive effect, making it possible to obtain a bridge output proportional to the pressure.

For this reason, the conventional method for determining semiconductor pressure sensors in a wafer process is to place the wafer of the semiconductor pressure sensor on a wafer stage and fabricate it on the surface of the wafer without applying pressure. The method used was to make measurements only electrically by bringing the electrodes and measurement probes into contact with each other.

<Problems to be solved by the invention> In the above method, measurement is not performed with pressure applied to the diaphragm, so the thickness of the diaphragm formed in each semiconductor pressure sensor by processes such as ion implantation and etching process is There is a problem that there is slight variation in the degree of deformation of the diaphragm in response to the actually applied pressure, and that highly accurate measurement cannot be performed. In addition, in order to prevent this variation, it is possible to measure the pressure sensitivity by applying pressure to the diaphragm for each chip after cutting out the wafer.
As mentioned above, since the chip size is small, this is not possible in practice, and there is a problem in that it is necessary to use it with slight variations allowed. Furthermore, it is conceivable to measure the pressure sensitivity after mounting the sensor chip in a package, but if the sensor chip does not have the desired pressure sensitivity, it will have to be discarded along with the package, which would result in a large amount of waste. There was a problem in that it was a waste of cost.
