High Resolution Powder Blast Micromachining
نویسندگان
چکیده
Powder blasting, or Abrasive Jet Machining (AJM), is a technique in which a particle jet is directed towards a target for mechanical material removal. It is a fast, cheap and accurate directional etch technique for brittle materials like glass, silicon and ceramics. By introducing electroplated copper as a new mask material, the feature size of this process was decreased. It was found that blasting with 9 pm particles (compared with 30 pm particles) result in a higher slope of the channel sidewall. The aspect ratio of powder blasted channels was increased by using the high resistance of the copper mask in combination with the use of 9 pm particles. Furthermore, our measurements show how the blast lag (small channels etch slower compared to wider channels) is decreased by using smaller particles.

متن کاملManufacturing costs for microsystems/MEMS using high aspect ratio microfabrication techniques
The emphasis on high aspect ratio micromachining techniques for microsystems/MEMS has been mainly to achieve novel devices with, for example, high sensing or actuation performance. Often these utilize deep structures (100–1,000 lm) with vertical wall layers but with relatively modest spatial resolution (1–10 lm). As these techniques move from research to industrial manufacture, the capital cost...
