construction is unreasonable primarily because it in graphs all sorts of explanations and gloss on the construction that are simply inconsistent with the way the invention is described the seven  limitation we submit that the limitation naturally reads as a single filling step it is filling the three type of the thirty three dollars specific openings with a layer to complete the context that's a single filling step that occurs and that's what's claim naturally requires filling to complete and that's that's something so you get a functional time that you have to fill to get a functional time data will leave aside the degree of fullness but just means you have to fill it and it has to be a filling process and that process is just that the overall process is designed to reduce the number of steps that are used during the formation of the semiconductor process and that's as a goal of this and so  specification just describe one way of accomplishing this result but the claim is much broader well she did and you know you're entitled to claim it more broadly as long as it's described  described in the specification there's no disclosure in the specification of of filling the holes separately which would require wholly additional masking processes that aren't disclosed you can't  isn't like something where you can just fill an individual hole and then fill in a separate individual all the way for this in a processing chamber and the conductive material is applied across the way for it so it's not if there's what the invention is describing and that's not what is appropriate in this context and the board have got hung up on the use of the word currently which appears earlier in the claim regarding the and that was necessary because the rate of claim was drafted there was a st edging step and a nd edging step in the clause and to refer to them occurring the same time they used the term concurrently but that doesn't mandate t exposed to substrate in the gate and if you fill them they would form a fully functional contact however that is a benefit is twenty one bead over it line five day there's a layer seven a on top of that at the silicon  and with the boards construction does is if in effect says if at any time you have three full contacts then this claim limitation is met and we would submit that that would cover anything in the prior art that's unreasonable ra versus the bottom of the other two contact holes and the board didn't made a findings that this was explicitly disclosed in the art and indeed samsung advanced a theory of in errancy that this was disclosed why they're here alternative aspect ratio construction claim to they just agree with that so i mean i guess one could always say somebody could have said more gone into more detail but you think  happened so there are two aspects here one is the aspect ratio and that was an argument presented below and or disposed of it the other was that we said look there are these conditions where what they say is happening in the time based process and specifically the conditions of multi with these specific action gases and conditions where you won't obtain the differential even though you have a good electrode that is higher in the three dimensional space and therefor let me jump right into the feeling that petition construction so as the court recognizes called us is trying to import three limitations into this very simple limitation from our perspective they want to say that it's one step that is concurrently it's the same material and you make the kind for the summit this intrinsic evidence simply does not limit the invention in such a manner so if we start with the concurrently limitation of the single step starting with a clean language it is a broad step filling it includes sub steps that as the board recognized and if you look at their other claim limitations specifically the current currently edging limitation they knew how to claim concurrently and i heard my colleagues say that this is the whole point of the invention that filling is the whole point of the invention that's simply not true their invention is about concurrently actually and they claim into the claim again that's simply not supported although of the experts here submitted testimony that said that a contract does not have to be one hundred percent full for it to be completely full and you can find testimony from sa so their claim constructions simply should be rejected unless any questions of the claim to such an issue i'd like to would claim that turning to the substantial evidence issues they obviously i think it basically comes down to they wanted better written decision also recognized the sound so he actually made an alternative argument obviousness based on a car engine and you can see that at appendix twenty one at the top then if you can jump to appendix twenty six the board then carefully fact that they used the same material is not in and of itself a lot of not to give rise to the same as an effects that temperature pressure lots of other factors that come into play with respect to the claim construction issue  we believe that the ords construction is simply overbroad in an effort to capture the prior art and to include any possible steps that might occur in any intervening processes and we don't think that the
