Thick layer of toner etch
WebIn the case of some shallow etches, a thick layer of negative photoresists (i.e., SU-8) may be a simple, low cost but suitable masking material. In another research, a positive photoresist (AZ4330) in combination with a Cr/Au mask was used in order to wet etch glass in 49 wt% HF solution (Jin, Yoo, Bae, & Kim, 2013). Anisotropic wet etching of ... At this point, with the toner transfer process itself pretty much dialed in, the limiting factor in how reliably and at what resolution you can print is going to be the printer itself and the software that drives it. I found surprisingly large differences between different printer drivers (PCL and Postscript) as well as between … See more A lot of Internet toner-transfer guides focus on details that don’t really matter, like the type of paper used for the transfer medium or the method of cleaning the copper before ironing. That’s not to say that you don’t need to … See more On the other hand, there are three fundamental factors that matter for the adhesion of the toner to copper, and it’s down to physics: time, temperature, and pressure. It’s a huge step towards reliability and … See more So everything interacts: temperature, pressure, paper type, and even the file format and printer drivers. I gave up experimenting for today because I’m content with reliable 6/8 traces, and when I need to push it even … See more

WebBake the SiO2 at 700C to increase adhesion. Vapor prime with HDMS to increase adhesion. Use photoresist designed for wet etching with optimized adhesion. Thicker photoresist (10-micron) holds up ... WebEtching the SiO 2 layer was carried out using a dry etching process. The etchant was CHF 3 gas, and the etching time was examined, because this strongly influences the quality of the grooves after Si substrate etching. The anticipated effect is illustrated in Figure 5.56.If the SiO 2 etching time is too long, the etched line width of the SiO 2 layer will become wider …
The two fundamental types of etchants are liquid-phase ("wet") and plasma-phase ("dry"). Each of these exists in several varieties. The first etching processes used liquid-phase ("wet") etchants. This process is now largely outdated, but was used up until the late 1980s when it was superseded by dry plasma etching.
