Dear MEMS team.. Is there any way of making two V grooves (one smaller and one bigger) touching each other? smaller one has dimension of 75 microns width and larger has dimension of 225 microns wide.. I mean there has to be no gap between the two V groove and smaller V groove opens up to a larger V groove like a channel.. I am trying the wet etching using some techniques like giving a small gap between the two V grooves and etch it in KOH. but not working.. is there any other techniques anyone can suggest me or any suggestions in wet etching by which i can get the desired results? thanks ganesh Ganesh R.
