1、By:Wen-Jen Liu Date:04/30/2001 page:1Photo:Raw material:Reticle,Photo ResistEquipment:I-Line(MUV),DUV,EUV(Stepper,SCANNER)Vendors:Nikon,ASML2.Module definition-PHOTOThe PHOTO concept was general Optics lithography to reproduce the specific patterns.Today we deployed the UV Excimer laser for the ligh
2、t,According to Optics principle,generally the wavelength of the light should be less than one tenth of half pitch,so if the technology shrink,the Exposure light source should be pushed into deeply UV zone.By:Wen-Jen Liu Date:04/30/2001 page:2Thin-Film:Raw material:Metal Target,ChemicalEquipment:Sput
3、ter,RTP,CVD(AP,PE,LP,SP,MO),ScubberVendors:AMAT,Novellus,TEL,ASM.2.Module definition-Thin FilmIn general we can split the Thin-Film into two field,one is Physics dominated(PVD),the other is Chemical dominated(CVD)The PVD means that no chemical reaction assisted in the process,just simply accelerated
4、 Ar atom to bombard the target to evaporate the target and deposit on the wafer,such likes Sputter.The CVD means that the chemical reaction on the wafer or chamber to deposit a film on the surfaceCVDPVDChemical reactionBy:Wen-Jen Liu Date:04/30/2001 page:3EtchRaw material:Solvent,Reactive gasEquipme
5、nt:Dry Etch(RIE),Wet Bench(Chemical Station)Vendors:AMAT,Novellus,TEL,ASM.2.Module definition-ETCHIn general we can call that RIE in the term of Dry etching,the dry etching which dominated by the Physical Ion bombard and chemical reaction with the surface to evaporated the byproducts.Reactive ion bo
6、mbardBy:Wen-Jen Liu Date:04/30/2001 page:4DiffusionRaw material:Chemical Gas,Isotope gasEquipment:Implanter,Furnace Vendors:Eaton,Varian,KE,TEL.2.Module definition-Diffusion In the diffusion,therere two methods to deliver the dopant into the silicon wafer:.Implant:To accelerate the isotope and direc
7、t bombard the wafer to deliver the dopant into right depth with right concentration.Furnace:To use thermal diffusion potential to deliver the dopant into right depth with right concentration.By:Wen-Jen Liu Date:04/30/2001 page:5CM PRaw material:Slurry,polish padEquipment:CMP(W-CMP,Oxide-CMP,Cu-CMP)V
8、endors:AMAT,COBAT,Strasbaugh2.Module definition-CMPIn general,the CMP like the polish arts,but deployed the chemical-mechanical assistant.Therere two factors dominated the CMP process:.First is chemical hydrolysis slurry to hydrolyze the surface,.Second is the slurry abrasive to remove the hydrolyte
