If our standard silicide process was used, low levels (Detection limit E10 cm/sup -2/) of Co were retained regardless of substrate and process conditions. Increasing RTA temperature of Co films that have not been capped with titanium (Ti) had relatively high uniform concentration levels throughout the annealing range. If the Co films are Ti capped the Co decreased in concentration with an increasing annealing temperature. The Ti retention however started several orders of magnitude higher than that of Co and increased slightly with increasing temperature. Pre-cleaning with Ar/sup +/ plasma and with aggressive strip led to lower retention of Co and Ti. Undoped silicon oxide was very temperature sensitive and retains more Co than Si/sub 3/N/sub 4/ or thermal SiO/sub 2/ films. Thermal oxide films behave similar to silicon nitride. Chemical bonding data suggest that cobalt combines with silicon, near the surface (>20A). Titanium capping, annealing temperature, free silicon in substrates, chemical strip and film surface conditions are the determining factors for the level of retention. Residual Co and Ti can be nearly eliminated if an additional post RTA wet strip (aggressive) is used, but it must be metered with knowledge that it will be done at the expense of Co silicide removal from poly gate and active regions.","PeriodicalId":104122,"journal":{"name":"Proceedings of ISSM2000.

As the result, it was clarified that the composition of 0.1:0.1:5 (NH/sub 4/OH:H/sub 2/O/sub 2/:H/sub 2/O) in the one-bath type wet-bench is almost equivalent cost level to the conventional multi-bath type wet-bench and can realize the high controllability and performance for the pre-cleaning of multi gate oxide.","PeriodicalId":104122,"journal":{"name":"Proceedings of ISSM2000.

This focus has produced dramatic results. Since its inception, the semiconductor industry has achieved productivity improvements unmatched by any other industry. Shrinking feature sizes, larger wafers, yield improvements and other productivity gains have contributed to this success. However, most of the known technological capabilities will be approaching or have reached their limits within 10-15 years. Already, larger wafers and improved yields are making a smaller contribution to productivity improvements than they have in the past, creating a widening gap in the productivity curve. This paper discusses how automated material and information flow can help close this gap in the productivity curve, and results that have been achieved.","PeriodicalId":104122,"journal":{"name":"Proceedings of ISSM2000.

In this work, we introduce and validate such a model. Using a small number of input parameters, we explain current yield management practices in 200 mm factories. The model is then used to extrapolate requirements for 300 mm factories, including the impact of simultaneous technology transitions to 130 nm design rules, copper interconnect, and integrated metrology. We show that the dramatic increase in value per wafer at the 300 mm transition becomes a driver for increasing metrology capability, despite a concomitant increase in cost. As expected, the model results are strongly dependent on product type (memory, chipset, or microprocessor) and process maturity.","PeriodicalId":104122,"journal":{"name":"Proceedings of ISSM2000.

The largest item on the cost Pareto is capital depreciation and the most significant item in reducing it is an efficient reuse program. Until now all tool reuse was done in one site, using older tools. The breakthrough of the Intel Fab 18 tool reuse program is that 100% of the reused tools have been delivered from other sites overseas. Some of the difficulties of being an International green field Fab were different power supply amplitude/frequency, conversion in a remote site, demolition, crating, shipping, etc. The program included over 50 tool types and 181 process tools. It was all managed using a Web based tracking tool. The Web based tool enabled each machine owner to modify and track the status of the tool for each critical project milestone online. The Fab 18 program was very successful, giving cost saving to Intel while controlling risk.","PeriodicalId":104122,"journal":{"name":"Proceedings of ISSM2000.

However, it took time to determine the source of particles using conventional particle analysis methods such as EDX and FT-IR, due to shortcomings arising from their measurement principles. Raman spectroscopic analysis is a method for analyzing particles which compensates for the insufficiencies of conventional analysis methods, so there is possibility that it will enable the determination of particle sources in a shorter period of time. We selected four types of 64 M D-RAM production equipment where particles originating from that manufacturing equipment were considered to be reducing yields.","PeriodicalId":104122,"journal":{"name":"Proceedings of ISSM2000.
