    Abstract: A method of manufacturing a semiconductor device wherein a laminate structure comprising a sacrificial layer is sandwiched between two etch stop layers (8,11) and which separates a semiconductor membrane (9) from a bulk substrate (1) is used to provide an underetched structure. Access trenches (4) and support trenches (5) are formed in the layered structure through the thickness of the semiconductor layer (9) and through the upper etch stop layer (8). The support trenches extend deeper through the sacrificial layer (12) and the lower etch stop layer and are filled. The sacrificial layer is exposed and etched away selectively to the etch stop layers to form a cavity (30) and realise a semiconductor membrane which is attached to the bulk substrate via a vertical support structure comprising the filled support trenches.

    Abstract: The fabrication of a MEMS device such as an interferometric modulator is improved by employing an etch stop layer between a sacrificial layer and a an electrode. The etch stop may reduce undesirable over-etching of the sacrificial layer and the electrode. The etch stop layer may also serve as a barrier layer, buffer layer, and/or template layer. The etch stop layer may include silicon-rich silicon nitride.

    Abstract: A method is for manufacturing a microstructure having a thin-walled portion with use of a material substrate. The material substrate has a laminated structure which includes a first conductor layer 101, a second conductor layer 102, a third conductor layer 103, a first insulating layer 104 interposed between the first conductor layer and the second conductor layer, and a second insulating layer 105 interposed between the second conductor layer and the third conductor layer. The first insulating layer is patterned to have a first masking part for covering a thin-wall forming region of the second conductor layer. The second insulating layer is patterned to have a second masking part for covering the thin-wall forming region of the second conductor layer. The method includes forming the thin-walled portion in the second conductor portion by etching the material substrate from the first conductor layer down to the second insulating layer via a mask pattern 58 including a non-masking region corresponding to the thin-wall forming region of the second conductor layer.
