Line inspection found particle contamination on bondpads and large metal 1 lines of some wafers. Cross sectional SEM results showed that some nodules were found in the metal 1 layer. EDX analysis confirmed that they were Si nodules as a high Si peak was detected on the nodules. These nodules had resulted in open failure in some metal lines. Based on the failure analysis results, we concluded that the silicon nodules were due to silicon precipitation. The preventive actions taken were to check the target if the Si value in Al exceeds the normal value, to control the parameter strictly during metal deposition and to reduce the thermal cycles after metal deposition.","PeriodicalId":359114,"journal":{"name":"ICSE 2000. 2000 IEEE International Conference on Semiconductor Electronics.

Surface and cross sectional SEM (scanning electron microscopy) was used to identify the root cause. After poly etching, particle contamination was found at the N-well and field oxide overlap region. Some wafers were scrapped due to this issue. To identify the root cause and solution, some affected wafers were subjected to surface and cross sectional SEM. Surface SEM inspection found the particles at the edge of field oxide. Cross sectional SEM and EDX confirmed that it was poly residue. The residue was due to the high topography at the edge of the field oxide, thus causing higher poly thickness. The difference in height resulted in the vertical thickness of the slope of ONO and poly layers to be thicker than that of the planar layer. During the poly etch process, which was anisotropic, the planar poly could be etched away completely but the poly at the slope might not be etched away as it was thicker than the planar layer. Hence some poly residue was left behind. After investigation, the solutions used are to optimize the poly etching recipe by removing He clamp flow at the break through step, and to increase the isotropic etch and etching time from 80 s to 100 s. The poly residue is then eliminated after implementing the new etch recipe.","PeriodicalId":359114,"journal":{"name":"ICSE 2000. 2000 IEEE International Conference on Semiconductor Electronics.

EDX (energy-dispersive X-ray microanalysis) and AES (Auger electron spectroscopy) techniques were used to identify the possible root cause. Based on EDX and AES results, it is concluded that the bondpad peeling problem was due to significant carbon contamination on the peeled area of the bondpad, which might contribute to the bondpad peeling problem. EDX and AES results also confirmed the peeling occurred between the barrier metal and BPSG layers. The high C contamination had resulted in poor adhesion between the barrier metal and BPSG layers and resulted in the peeling problem. The high C contamination on the BPSG layer was introduced during the wafer fab process. It may be due to incomplete contact process resist strip or insufficient pre-clean before barrier metal deposition. In this paper, we also discuss the difference between EDX and AES analysis techniques and use the contamination diagram introduced by us.","PeriodicalId":359114,"journal":{"name":"ICSE 2000. 2000 IEEE International Conference on Semiconductor Electronics.

A p-type silicon [100] wafer is etched under four RF power levels, which are 40, 60, 80 and 100 W. The etch depth plotted shows a linear increase with RF power for a fixed etch time at low RF power. However, the etch depth shows a tendency to saturate at a higher RF power level. The behaviour is believed to be caused by the existence of a sheath layer when plasma is generated in the process chamber.","PeriodicalId":359114,"journal":{"name":"ICSE 2000. 2000 IEEE International Conference on Semiconductor Electronics.
