Method of Providing a Plurality of Through-Holes in a Layer of Structural Material
A method of providing a MEMS device including a through-hole in a layer of structural material using a multitude of MEMS method steps. A versatile method to create a through-hole, in particular a multitude thereof, involves a step of exposing a polymeric layer of positive photoresist in a direction from the outer surface of the positive photoresist to light resulting in an exposed layer of positive photoresist including relatively strongly depolymerized positive photoresist in the top section of a recess while leaving relatively less strongly depolymerized positive photoresist in the bottom section of the recess.

The invention is to reduce non-uniformity of a processing shape over a wide range of a single field-of-view. The invention is directed to a method of processing micro electro mechanical systems with a first step and a second step in a processing apparatus including an irradiation unit that irradiates a sample with a charged particle beam, a shape measuring unit that measures a shape of the sample, and a control unit. In the first step, the irradiation unit irradiates a plurality of single field-of-view points with the charged particle beam in a first region of the sample, the shape measuring unit measures the shape of a spot hole formed in the first region of the sample, and the control unit sets, based on measurement results of the shape of the spot hole, a scan condition of the charged particle beam or a forming mask of the charged particle beam at each of the single field-of-view points. In the second step, the irradiation unit irradiates, based on the scan condition or the forming mask set in the first step, a second region of the sample with the charged particle beam.

High-density soft-matter electronics
The disclosure describes a soft-matter electronic device having micron-scale features, and methods to fabricate the electronic device. In some embodiments, the device comprises an elastomer mold having microchannels, which are filled with an eutectic alloy to create an electrically conductive element. The microchannels are sealed with a polymer to prevent the alloy from escaping the microchannels. In some embodiments, the alloy is drawn into the microchannels using a micro-transfer printing technique. Additionally, the molds can be created using soft-lithography or other fabrication techniques. The method described herein allows creation of micron-scale circuit features with a line width and spacing that is an order-of-magnitude smaller than those previously demonstrated.
METHOD AND APPARATUS FOR ETCHING A SUBSTRATE
The invention relates to the field of method of etching a substrate (W), in particular a wafer, in order to produce a grid of micro-protrusion. Such grid of micro-protrusion is generally made using UV photolithography followed by wet and chemical engraving with an etching solution. Most of the currently available methods do not lead to an even attack of the wafer surface by the etching solution because the reaction produces a release of micro-bubbles which, if not properly evacuated, disturb the etching process. In the present invention, substrate(s) (W) are disposed on a magnetic supporting device (1) which is driven in rotation in the etching solution via a magnetic agitator external to the etching solution, so that the magnetic supporting device (1) causes the substrate to rotate at least in a same direction the magnetic supporting device (1). The present invention makes it possible to obtain substrates with good homogeneity.
