Description
KL6000 Thick-Film i/g-Line Positive Photoresist is designed for advanced packaging, TSV, bumping, and electroplating applications that demand reliable thick-film builds. The KL6000 series supports 2.5–12 µm single-coat films with high sensitivity, high throughput, and excellent process latitude. Optimized for 0.26 N TMAH developers and requiring no post-exposure bake, KL6000 streamlines cycle time while maintaining consistent feature fidelity. As a practical, drop-in alternative to thick-film standards such as SPR® 220-3.0, 220-4.5, 220-7.0, and S1827, KL6000 provides a clean upgrade path for packaging lines seeking productivity without sacrificing performance.
Pricing valid for US, Mexico, and Canada only. Import duties applicable for shipments outside of the US.
