Filed: 1984-10-23
Abstract: PURPOSE:To obtain the informations to investigate causes to decrease the yield with little influence of the order of inspection, by calculating the fraction defective or percentage of passing of each inspection item corresponding to the position of each element in the wafer being based on the inspection data of wafers in the fail-stop system. CONSTITUTION:The probe inspection of the fail-stop system is performed about 20 wafers manufactured by the process in which the etching condition is intensionally biased to the right lower part of the wafer. The column a is a map showing the number of failure elements for each inspection item denoted as rk1ij and rk2ij. These are obtained from inspection examples and represent the value of zero, the single figure and the double figures with '.', its value and the alphabet in the order, respectively. It can be seen that many defects are apt to generate in the right lower part of the wafer in case of the inspection item k1 and the left upper part in case of k2, and the distribution of fraction defective of the inspection item k2 does not reflect the biased condition of the process. The column C is a map showing the fraction defective fk1ij and fk2ij for each inspection item. The values are represented by the percentage whose first figure is counted fractions of 5 and over as a unit and disregarded the rest, and second figure is shown in the same way as the column a. The result shows that many defects are apt to generate in the right lower part of the wafer.

Filed: 1995-08-30
Abstract: PROBLEM TO BE SOLVED: To provide an optical assembly structure constituted by mounting a semiconductor element which generates large heat and an optical element which has high impedance on the same optical waveguide substrate. SOLUTION: The element 2 which generates large heat is adhered onto a projection part 11 of the semiconductor substrate 10 directly or across an insulator layer of thickness of about submicrons. The optical element 3 with high impedance, on the other hand, is put in a groove formed in a recessed part of the semiconductor substrate 10 so that its optical axis is aligned with an optical waveguide layer coupled with the element. Or the potential of the semiconductor substrate 10 is held as high as a source voltage or ground potential to invert the polarity of the substrate crystal of the heat generating element 2 which is biased forward and the reverse bias element 3 which has a problem of floating capacity.  Consequently, the element 2 which generates large heat and the high-impedance optical element 3 can be mounted on the same optical waveguide substrate while aligned with the optical axis of the optical waveguide 1. Consequently, a hybrid circuit having various optical elements and electronic elements built in on an optical waveguide can be mounted at low cost.
