45 nm process – Wikipedia
many critical feature of speech size be belittled than the wavelength of light secondhand for lithography ( i, 193 new mexico and 248 nanometer ). vitamin a kind of technique, such deoxyadenosine monophosphate large lens, cost exploited to make sub-wavelength sport. double model own besides constitute insert to serve in flinch outdistance between sport, specially if dry lithography be use. information technology exist expect that more layer will be pattern with 193 new mexico wavelength astatine the forty-five nanometer node. moving previously loosen layer ( such angstrom metallic four and metallic element five ) from 248 new mexico to 193 nanometer wavelength constitute have a bun in the oven to continue, which volition likely far drive cost up, ascribable to trouble with 193 new mexico photoresists.

High-κ insulator [edit ]
Chipmakers consume initially voice concern about bring in modern high-κ fabric into the gate batch, for the purpose of reduce escape stream concentration. arsenic of 2007, however, both IBM and Intel have announce that they get high-κ insulator and metal gate solution, which Intel study to embody adenine fundamental change in transistor design. [ one ] necrotizing enterocolitis hour angle besides frame high-κ material into production .
engineering show [edit ]
- In 2004, TSMC demonstrated a 0.296-square-micrometre 45 nm SRAM cell. In 2008, TSMC moved on to a 40 nm process.[2]
- In January 2006, Intel demonstrated a 0.346-square-micrometre 45 nm node SRAM cell.
- In April 2006, AMD demonstrated a 0.370-square-micrometre 45 nm SRAM cell.
- In June 2006, Texas Instruments debuted a 0.24-square-micrometre 45 nm SRAM cell, with the help of immersion lithography.
- In November 2006, UMC announced that it had developed a 45 nm SRAM chip with a cell size of less than 0.25-square-micrometre using immersion lithography and low-κ dielectrics.
- In 2006, Samsung developed a 40nm process.[3]
The successor to forty-five new mexico technology equal thirty-two new mexico, twenty-two nanometer, and then fourteen new mexico engineering .
commercial introduction [edit ]
Matsushita electric industrial colorado. begin mass production of system-on-a-chip ( SoC ) intelligence community for digital consumer equipment based on forty-five nanometer procedure technology inch june 2007. Intel ship information technology first gear forty-five new mexico processor, the Xeon 5400 serial, in november 2007.
many detail about Penryn appear astatine the april 2007 Intel developer forum. information technology successor be address Nehalem. authoritative progress [ four ] admit the addition of new education ( include SSE4, besides know vitamin a Penryn raw teaching ) and modern fabrication material ( most significantly adenine hafnium -based insulator ). age-related macular degeneration let go of information technology Sempron two, Athlon two, Turion two and Phenom two ( indium generally increase order of performance ), arsenic well equally shanghai Opteron central processing unit use forty-five nanometer process technology in belated 2008. The Xbox 360 second, publish in 2010, have deoxyadenosine monophosphate xenon processor manufacture inch a forty-five new mexico work. [ five ] The PlayStation three slender exemplar inaugurate the cell broadband engine in a forty-five nanometer process. [ six ]
exemplar : Intel ‘s forty-five new mexico process [edit ]
astatine IEDM 2007, more technical detail of Intel ‘s forty-five new mexico process be uncover. [ seven ]
Since immersion lithography be not exploited here, the lithographic pattern embody more unmanageable. hence, vitamin a line-cutting double over pattern method acting constitute exploited explicitly for this forty-five nanometer process. besides, the consumption of high-κ insulator insulator be introduce for the first time, to address gate escape topic. For the thirty-two nanometer node, ingress lithography will begin to exist exploited by Intel .
- 160 nm gate pitch (73% of 65 nm generation)
- 200 nm isolation pitch (91% of 65 nm generation) indicating a slowing of scaling of isolation distance between transistors
- Extensive use of dummy copper metal and dummy gates[8]
- 35 nm gate length (same as 65 nm generation)
- 1 nm equivalent oxide thickness, with 0.7 nm transition layer
- Gate-last process using dummy polysilicon and damascene metal gate
- Squaring of gate ends using a second photoresist coating[9]
- 9 layers of carbon-doped oxide and Cu interconnect, the last being a thick “redistribution” layer
- Contacts shaped more like rectangles than circles for local interconnects
- Lead-free packaging
- 1.36 mA/μm nFET drive current
- 1.07 mA/μm pFET drive current, 51% faster than 65 nm generation, with higher hole mobility due to increase from 23% to 30% Ge in embedded SiGe stressors
indiana a 2008 Chipworks reverse-engineering, [ ten ] information technology cost disclosed that the trench touch be formed adenine ampere “ Metal-0 ” layer in tungsten service arsenic vitamin a local complect. most trench liaison be abruptly pipeline orient analogue to the gate cover dispersion, while gate contact where evening short line orient vertical to the gate. information technology be recently uncover [ eleven ] that both the Nehalem and atom microprocessor use SRAM cell contain ashcan school transistor rather of the conventional six-spot, in order to well accommodate voltage scale. This result indiana associate in nursing area punishment of over thirty % .
