The aggressive design rules and border-less contacts/vias render an embedded (synchronous cache) 6T SRAM cell of 3.42 /spl mu/m/sup 2/ demonstrated in a 2Mb vehicle with very high yield.

Cu atoms intentionally adsorbed on backside of the wafers were diffused and were once gettered at the gettering sites during high-temperature drive-in diffusion. However, after low-temperature annealing following the drive-in diffusion, Cu concentration of the Si surface was found to increase even in CZ wafers with intrinsic gettering process (IG). Cu atoms gettered in the vicinity of the SiO/sub 2//Si interface after drive-in diffusion are found to readily transport through the SiO/sub 2/ film and reach the SiO/sub 2/ surface during 400/spl deg/C annealing. This transport of Cu is found to cause degradation of thin SiO/sub 2/ film. The redistribution phenomenon during low-temperature annealing should be carefully controlled in order to realize highly reliable CMOS devices.","PeriodicalId":268624,"journal":{"name":"2000 Symposium on VLSI Technology.

We report on anomalous diffusion of 1 keV arsenic implants where the same RTA anneal can result in a deeper junction compared to a 5 keV implant of similar dose. A range of anneal times and temperatures in an RTA from 1020C to 1175C, including spike anneals, have been studied. The effect of junction abruptness in reducing the external resistance of the S/D extension for these 5 and 1 keV As implants has been investigated. We show that because of a trade off between junction depth and sheet resistance limits, 1 keV As implants and RTA anneals cannot meet the technology roadmap requirements beyond 2005, though the junction abruptness will meet the requirements till 2011.","PeriodicalId":268624,"journal":{"name":"2000 Symposium on VLSI Technology.
