AX 100 - 5.00 l
nbtax1005
Bottle size:
5.00 l
AX 100
Activator
General Information
AX 100 is an acidic solution for activating and pretreating seed layers and metallic surfaces for electroplating, on which a direct metallization may cause problems regarding the adhesive strength. This applies e.g. for the electroplating of Au on Ni surfaces or direct electroplating on Ti or TiW layers.
AX 100 activates metallic surfaces before electroplating and allows a better adhesive strength of electroplated layers on metallic surfaces, which tend to oxidation.
Common fields of application are semiconductor fabrication and microsystem technology.
Product Properties
Low or none etch attack on metallic surfaces
Compatible to many materials, e.g. common metals used in electroplating industry
Compatible to resist masking
Not poisonous substance and easy to handle
Moderate operation temperature of about 40°C
Selectivity
AX 100 is compatible/etches selective to following materials:
Resists: common Novolak as masking resist (e.g. AZ® Photoresist)
Metals: no attack on Ni, Ti, TiW, Ta, Cu
Semiconductor materials: Si, SiO2, Si3N4

BOE 7:1 (87,5 : 12,5) - 2.50 l - VLSI - EVE/EUD!
TBOV1025
BOE 7:1
Buffered Oxide Etch
General Information
BOE is mainly used for etching glasses, quartz and SiO2 films.
We supply BOE 7:1 = buffered hydrofluoric acid (HF : NH4F = 12.5 : 87.5%) in VLSI-quality, which is the usual purity grades applied in semiconductor processing and micro-electronics.
NOTE:
BOE must be stored and transported above +12.5°C. Below this critical temperature of 12.5°C the material forms particles (little crystals). Since these crystals have a higher density, they will accumulate at the bottom of the bottle and will only be completely re-dissolved when the material is stored at temperatures of 30 - 35°C for some days. After this procedure the crystals should be re-dissolved completely and the BOE can be then used without restrictions.
