Conductive Coating AR-PC 5094.02 (Electra 92)

Top layer dissipation of electron beam charges on insulating substrate

A new product for both polymer and novolac-based EBL resist applications

Electra 92 Product Brief 產品說明

Electra 92 應用於電子束微影或顯微鏡分析,於絕緣基板上塗佈導電層,使電子束曝光時電荷得以逸散.由於產品持續不斷優化,從溶劑改良到產品穩定性,塗佈品質等不斷改善,目前最新通用型版本的產品編號為:AR-PC 5094.02
產品適用於各類型阻劑,例如CSAR 62 (複合高分子copolymer);Medusa 84 SiH (HSQ),酚醛樹酯(novolac),PMMA等,涵蓋大部份阻劑類型,但不適用CAR阻劑(化學放大型)註1
與舊版本產品比較,及其生產狀況,請參考與舊版產品比較
註1:適用於CAR type的版本目前開發中,待完成後發表。

Conductivity 導電度

Conductivity measurements of AR-PC 5094.02 layers obtained after spin
deposition. For thinner films, the resistance increases and the conductivity decreases.

Process hints
The conductivity may be varied by adjusting the thickness with different rotational speeds. Thicker layers of 90 nm thus have a 2.5 times higher conductivity as compared to 60 nm thick layers. For the build-up of an even conductive layer, the substrate should be wetted with the resist solution before the spin process is started.
導電度可依導電層厚度加以調節. 90nm厚的導電層比60nm厚其導電度高約2.5倍.
導電層塗佈前先以阻劑的溶劑濕潤基板可獲得較均勻的厚度.
