The engineering run will use ladders consisting of Ultimate-1 and Ultimate-2 sensors.The production detector will use Ultimate-2 sensors only.

Joe Silber - Attached are measurements I made yesterday.

1) If I divide the total width of 10 butted sensors by 10x Leo's

nominal width (19.62mm) I get an average gap of 2um.

2) If I instead divide by the width I measured (19.607mm) then I getaverage gap of 16um.3) If I add up the worst cases of offset and rotation that I measured,then the maximum

tol envelope would be 54um.4) If I add up the stdevs on offset and rotation that I measured, then

the tol envelope should be 18um.Clearly I may be simply interpreting the edge of sensor incorrectly

due to my lighting conditions. If so, then the average gap is is tiny,2um, as in case (1). But if I am seeing things correctly on thesmartscope, then this batch of sensors were cut undersized by about

13um on average, and the correct gap to model would be more like16-18um, as in cases (2) and (4). Case (3) is essentially what Howardoriginally assumed (2 mil), but in reality it looks to me like itwould be incorrect for us to assume this worst-case placement on every

sensor.I think the bottom line is that if Leo can stomach about 100um maximumerror for wire bond alignment, then we should be fine splitting thedifference between the 2 um and 18 um numbers,

and calling the nominalgap 10um.Slide17
