Title: | A study of the undercutting characteristics in the TMAH:IPA system |
Authors: | Merlos Domingo, Ángel CSIC ORCID ; Acero Leal, María Cruz ; Bao, Min-Hang; Bausells, Joan CSIC ORCID ; Esteve i Tintó, Jaume | Issue Date: | 1-Jun-1992 | Publisher: | IOP Publishing | Citation: | Journal of Micromechanics and Microengineering 2(3): 181-183 (1992) | Abstract: | A new etching system of tetramethyl ammonium hydroxide-2-propanol (TMAH-IPA) is suggested. The undercutting ratio for TMAH at 80 degrees C is about 7, much higher than for KOH etchants. The addition of IPA in the TMAH system maintains the main features of TMAH and reduces the undercutting ratio by a factor of 2-3. | Description: | Trabajo presentado en el Micromechanics Europe 1992 (MME'92), celebrado en Lovaina (Bélgica), los días 1 y 2 de junio de 1992 | Publisher version (URL): | http://dx.doi.org/10.1088/0960-1317/2/3/014 | URI: | http://hdl.handle.net/10261/258075 | Identifiers: | doi: 10.1088/0960-1317/2/3/014 issn: 0960-1317 e-issn: 1361-6439 |
