Abstract: PROBLEM TO BE SOLVED: To prevent the dislocation and slip in crystals in a high-temperature heat treatment atmosphere by locating groups of stacked wafers vertically in stages, with one group on one stage, in a soaking region of a heat-treatment furnace and then heat-treating them. SOLUTION: Surface-etched silicon single crystal wafers 1 are stacked in groups of ten wafers, and total 30 groups of wafers 1 which means 300 wafers all told are mounted vertically in stages in a heat-treatment boat 20. When the heat-treatment boat 20 is put into a cylindrical heat-treatment furnace, the temperature of the furnace is 700 deg.C. Then, the temperature is increased at a rate of 8 deg.C/minute up to 1000 deg.C and then at a rate of 1 deg.C/minute up to 1300 deg.C. The furance is kept at 1300 deg.C for two hours. After that, the temperature is decreased at a rate of 1 deg.C/minute down to 1000 deg.C and then at a rate of 2.5 deg.C/minute down to 700 deg.C. When the temperature becomes 700 deg.C, the heat- treatment boat 20 is taken out of the furnace.

Title: Sensor for recognizing surface shape
Inventor: MORIMURA HIROTOSHI
IPC: G06T1/00
Filed: 1998-07-02
Abstract: PROBLEM TO BE SOLVED: To accurately detect small roughness, such as a finger print, by detecting the difference between the first capacity between upper and lower electrodes and a second capacity between the upper and reference electrodes. SOLUTION: When a protective film 106 is deformed since a projection 106 touches a target, an upper electrode 105 is also deformed. As a result, the distance between lower and upper electrodes 104 and 105 changes, and a capacity Cf between them changes. At the same time, the distance between a reference electrode 104a and the upper electrode 105 changes, and a capacity Cr between them also changes. At this time, change in the distance between the electrode 104a and the electrode 105 is small as compared with the change in the distance between the electrode 104 and the electrode 105. The relation between the change in the capacity Cf and that in the capacity Cf does not depend on the height of a support member 103. Therefore, the difference in the capacity change is detected as an electrical signal by a sensor circuit 110.  When the value exceeds threshold, it is detected that the deformation of the part of the projection 106a has occurred, thus detecting the roughness of the target.
