Proposed 450 mm transition
There is considerable resistance to the 450 mm transition despite the possible productivity improvement, because of concern about insufficient return on investment.[17] Higher cost semiconductor fabrication equipment for larger wafers increases the cost of 450 mm fabs (semiconductor fabrication facilities or factories). Lithographer Chris Mack claimed in 2012 that the overall price per die for 450 mm wafers would be reduced by only 10–20% compared to 300 mm wafers, because over 50% of total wafer processing costs are lithography-related. Converting to larger 450 mm wafers would reduce price per die only for process operations such as etch where cost is related to wafer count, not wafer area. Cost for processes such as lithography is proportional to wafer area, and larger wafers would not reduce the lithography contribution to die cost.[18] Nikon planned to deliver 450-mm lithography equipment in 2015, with volume production in 2017.[19][20] In November 2013 ASML paused development of 450-mm lithography equipment, citing uncertain timing of chipmaker demand.[21]
The timeline for 450 mm has not been fixed. Mark Durcan, CEO of Micron Technology, said in February 2014 that he expects 450 mm adoption to be delayed indefinitely or discontinued. “I am not convinced that 450mm will ever happen but, to the extent that it does, it’s a long way out in the future. There is not a lot of necessity for Micron, at least over the next five years, to be spending a lot of money on 450mm. There is a lot of investment that needs to go on in the equipment community to make that happen. And the value at the end of the day – so that customers would buy that equipment – I think is dubious.”[22] As of March 2014, Intel Corporation expected 450 mm deployment by 2020 (by the end of this decade).[23] Mark LaPedus of semiengineering.com reported in mid-2014 that chipmakers had delayed adoption of 450 mm “for the foreseeable future.” According to this report some observers expected 2018 to 2020, while G. Dan Hutcheson, chief executive of VLSI Research, didn’t see 450mm fabs moving into production until 2020 to 2025.[24]
The step up to 300 mm required major changes, with fully automated factories using 300 mm wafers versus barely automated factories for the 200 mm wafers. These major investments were undertaken in the economic downturn following the dot-com bubble, resulting in huge resistance to upgrading to 450 mm by the original timeframe. On the ramp up to 450 mm are that the crystal ingots will be 3 times heavier (total weight a metric ton) and take 2–4 times longer to cool, and the process time will be double.[25] All told, the development of 450 mm wafers requires significant engineering, time, and cost to overcome.
lenže on si ho logicky asi neobjedná, že?
pointa je v čom ? Že ty si vieš je fajn v čase keď sme sa o tom bavili boli na alze 8086K ešte po cca 400 eur. Preto tu bol ten fuzz, že zobral 8700k za 470 ...
- jeden z Vás spomínal nejakú 390€ cenu čo imho bola najnižšia cena a to presne v Bonuskovi 
. Pointa je ale niekde úplne inde. Hlavne ked som daval do košíka na stránke mali uvedených 5ks skladom.takze 2. Den a furt nič.Ukazuje mi že sa vybavuje dorucenie na predajnu a čas je uvedený na zajtra poobede ale ajtak tomu neverim ze to dostanú,ked ich stranka alzy od vcera rána nemá už v ponuke ked to nepride pockam asi na 9900 ale otazka je ci bude stacit doska z370 s uptadnutým biosom alebo saz novu.vtom pripade by to vyslo pomaly 700 eur a ked to bude tak vtom pripade nato tiez dlabem.a pockam kym budu zas 8700 skladon lebo ten silnejsi co ste mi tu velice radili ))) kazdopadne alza zas sklamala " prozatím" že Leon...v tom čase už nebolo na Alza nič...len zelené stavy písmenok, čo dosť nechápem lebo aj u nás funguje, že ak si človek objedná zo skladového stavu tak objednávkou sa automaticky odpisuje a reálne to vidí aj zákazník.... vypredané a cena je bez dph Tažko by bol "lepší" procák lacnejší...jedine tak na heureke a nerealna dostupnost aj cena Ak tej dostupnosti - počas toho dňa keď sme sa bavili tak tam tie kusy fakt boli (8700K aj 8086K), nahadzovali a vymazávali ich do eshopu asi 3x počas dňa. To sa môžeme naťahovať od rána do večera čo tam znamenajú tie zelené čísielka. Ja beriem čo tam mali zverejnené na eshope. Veď uvidíme či to dostane.
A este potom skuste nejaku tu reklamaciu - to bude bonus naviac
