  • Abstract
    Chemical etching of sacrificial layers is a widely used technique in surface micromachining. The causes of the triangle at the etch front are analyzed. The viewpoint that stress is the major factor of the triangle´s formation is put forward. Through a study of the mechanism of the effects of annealing on etch rate, several rules about different annealing conditions having different effects on the etch rate are advanced.
