Kini idi ti silicon dioxide nano lulú le ṣee lo fun CMP?
Nano-silica ni o ni jo kekere iye owo, andgood dispersibility, darí abrasion, ga agbara ati adhesion, ti o dara fiimu Ibiyi, ga permeability, ga oju ojo ati wọ resistance, kekere patiku iwọn, líle.O tun ni awọn anfani ti iwọntunwọnsi, iki kekere, adhesion kekere, ati mimọ irọrun lẹhin didan.Nitorinaa o jẹ ohun elo didan fun imọ-ẹrọ CMP pẹlu iṣẹ ṣiṣe to dara julọ.
SiO2 nano patiku nigbagbogbo lo fun didan ti irin, oniyebiye, ohun alumọni monocrystalline, awọn ohun elo gilasi, tube itọsọna ina ati awọn aaye miiran.Iwọn ohun elo afẹfẹ silikoni nano wa ni isalẹ 100nm, eyiti o ni agbegbe dada nla kan pato, dispersibility giga ati permeability, nitorinaa Layer bibajẹ lori dada ti didan workpiece jẹ lalailopinpin kekere;ni afikun, awọn líle ti silica nanoparticle jẹ iru si ti ohun alumọni wafers.Nitorinaa, o tun lo nigbagbogbo fun didan awọn ohun alumọni ohun alumọni semikondokito.
Awọn anfani ti nano SiO2 lulú ni ohun elo CMP:
