Semiconductor Nnuru a Wɔde Sie

Aguade no mu titiriw: Jiangsu RANA semiconductor nnuru akorae tank no yɛ semiconductor-grade a ɛkorɔn-ahotew a wɔayɛ no foforo PFA lining, a wɔayɛ wɔ 9000m2PPB/PPT grade dan a ɛho tew mu. Ɛnam ɔhyew a wɔde mia so no so no, enya "zero leaching, zero pollution" bonding, na wɔayɛ no titiriw ama nnuru a ɛho tew kɛse-a wɔde di dwuma wɔ semiconductor adwumayɛ mu (te sɛ kɔbere etching nsu, stripping nsu).

Mfaso a ɛwɔ akansi mu: Sɛ́ China Semiconductor Industry Association no muni no, yɛn nneɛma no anya adansedi krataa afi SMIC ne Taiwan, China Qiaoli Chemicals hɔ, a ɛkyerɛ sɛ dade ion a ɛwɔ mu no nnu anaasɛ ɛyɛ pɛ 0.05ppb (nnwuma mu gyinapɛn 0.1ppb) ne nneɛma nketenkete kɛse a ennu anaasɛ ɛyɛ pɛ 0.05μm (nnwuma gyinapɛn 0.1μm). Wɔde anti-static coatings (surface resistance<=10^9Ω) ahyɛ mu, wosiw electrostatic adsorption a ɛba nneɛma nketenkete mu ano yiye bere a wɔhwɛ hu sɛ dielectric ahotew.

Nsɛm a wɔde di dwuma: Wɔde di dwuma wɔ semiconductor wafer adwumayɛ mu (te sɛ photoresist nkɔso, dade etching), nneɛma a wɔde kyekyere nneɛma ne sɔhwɛ, ne nea ɛkeka ho, te sɛ kɔbere etching nsu a wɔde sie wɔ chip adwumayɛbea ahorow, bere tiaa mu nsu a wɔde tew nneɛma a wɔde sie wɔ nneɛma a wɔde kyekyere nneɛma ne adwumayɛbea ahorow a wɔsɔ hwɛ mu, ne nea ɛkeka ho, a ebetumi atew chip sintɔ a efĩ (te sɛ line trɛw mu mfomso so fi 5 μm kosi 3μm), na boa adetɔfoɔ ma wɔtu mpɔn wɔ high-end chips aba.
