产品介绍
钛蚀刻剂是应用于半导体制作和薄膜微电子技术的选择性控制蚀刻剂。
钛蚀刻剂TFTN用来蚀刻玻璃或SiO2基板上的Ti沉积膜。TFTN不含氢氟酸。 Titanium Etchant TFTN,Intended for etching Ti films deposited on glass or SiO2 substrates. TFTN does not contain hydrofluoric acid. 钛蚀刻剂TFT设计用来蚀刻通常在微电子产品中作为连结层和阻挡层的蒸发法薄膜的蚀刻剂。这种蚀刻剂光刻胶匹配性良好、分辨率高、边下蚀现象低。 Titanium Etchant TFT designed for etching evaporated films commonly employed as bonding and
barrier layers in microelectronics. Excellent resolution, photo resist
compatibility, and minimal undercutting are readily achieved.

PROPERTIES OF TRANSENE TITANIUM ETCHANT TFTN
| How do I increase the etch rate? | 1. The rate will approximately double with every 10°C increase in temperature. | | 2. Increase the rate of stirring or agitation. | | How do I reduce the etch rate? | Adding 1 part deionized water to 2 parts etchant will reduce the etch rate approximately 50%. | | Do I need to dilute the etchant? | No, it is ready to use. | | How do I reduce undercutting? | Increase the rate of stirring or agitation. | | Appearance | Clear, colorless | | pH | Strongly acidic | | Etch Rate at 70°C | 10 Å/sec. | | 85°C | 50 Å/sec. | | Etch Capacity (rate declines at ~70%) | 65 g/gallon | | Shelf Life | 1 year | | Storage Conditions | Ambient | | Filtration | 0.2 um | | Recommended Operating Temperatures | 20-80oC (30-40oC most common) | | Rinse | Deionized water | | Photoresist Recommendations | KLT6000 Series, KLT 5300 Series, HARE SQ (SU-8 type), TRANSIST, or PKP-308PI | | Select Compatible Materials | Au, SiO2, nitride | | Select Incompatible Materials | Cu, Al | | Compatible Plastics | HDPE, PP, Teflon, PFA, PVC | | Country of Origin | USA | | Availability | 1-2 days | | Packaging | HDPE | | Isotropy | Isotropic | | Incompatible Chemicals | Strong bases |
