A nanostructure pattern which includes pairs of metal lines separated by identical gaps whose dimensions are in the nanometer range, can be prepared by providing a separating sacrificial layer, whose dimensions can be controlled precisely, in the separation gap between the first metal line and the second metal line. The sacrificial layer is removed at the end of the fabrication, leaving a precisely dimensioned gap between the lines.

Nanostructure for molecular electronics comprising collinear metal lines defining precise nanoscale gap

The present invention relates to a molecular sensor for detecting the presence of a target analyte comprising a nitro-containing explosive molecule, the sensor comprising: a support substrate; a pair of electrodes comprising (i) a first electrode and (ii) a second electrode, wherein at least one of (i) and (ii) is at the substrate; an electron donor (ED) molecule capable of forming an electron donor-acceptor (EDA) complex with the nitro-containing explosive molecule; and wherein the ED molecule is disposed between the electrodes and is attached to each electrode by an alligator clip comprising a pendant group, thereby forming a nanojunction between the electrodes; a detection means operably connected to the pair of electrodes, the detection means capable of detecting a change in the electrical resistance or in the capacitance of the sensor when the ED molecule forms an EDA complex with the explosive molecule, the sensor thereby detecting the presence of the explosive molecule. Also disclosed are methods of making and methods of using the sensor.

Molecular sensors for explosives

Electronic circuits based on molecular transistors, generally used in place of semiconductors. More particularly, the invention relates to a unique method of wiring of a three-terminal molecule (or an aggregate thereof) to serve as an electronic transistor, containing a gate electrode, a source electrode, and a drain electrode. The source electrode and drain electrode are fabricated from one metal and the gate electrode is fabricated from another metal. The usage of molecular properties in this context provides significant advantages over the fabrication methods of the prior art.

Electrical contacts for molecular electronic transistors

Radiation sensitive silicon-containing negative resists and use thereof

Compositions comprising a polymer having silicon, germanium and/or tin; and a protecting group grafted onto a polymeric backbone are useful as resists and are sensitive to imaging irradiation while exhibiting enhanced resistance to reactive ion etching.

Polymers and use thereof

Antireflective compositions characterized by the presence of an SiO-containing polymer having pendant chromophore moieties are useful antireflective coating/hardmask compositions in lithographic processes. These compositions provide outstanding optical, mechanical and etch selectivity properties while being applicable using spin-on application techniques. The compositions are especially useful in lithographic processes used to configure underlying material layers on a substrate, especially metal or semiconductor layers.

Antireflective silicon-containing compositions as hardmask layer

Compositions comprising a polymer of organometallic polymerizable monomer acid or ester are useful as resists and are sensitive to imaging irradiation while exhibiting enhanced resistance to reactive ion etching.

Organometallic polymers and use thereof

The reactive ion etching resistance of radiation sensitive resist composition is enhanced by adding at least one organometallic compound to a radiation sensitive polymer. The resist composition can be patterned and used as mask for patterning an underlying layer.

Plasma resistant composition and use thereof

The invention provides improved resist compositions and lithographic methods using the resist compositions of the invention. The resist compositions of the invention are acid-catalyzed resists which are characterized by the presence of an SiO-containing polymer. The invention also encompasses methods of forming patterned material layers (especially conductive, semiconductive, or magnetic material structures) using the combination of the SiO-containing resist and a halogen compound-containing pattern transfer etchant where the halogen is Cl, Br or I.

Mask-making using resist having SIO bond-containing polymer

Photoresist compositions of improved reactive ion etching comprising polymers of 2-hydroxyalkyl methacrylate and/or 2-hydroxyalkylacrylate and a titanate, zirconate and/or hafnate are provided. The photoresist compositions are used for forming positive lithographic patterns.

RIE etch resistant nonchemically amplified resist composition and use thereof

High sensitivity, photo-active polymer and developers for high resolution resist applications

A method of improving the etch resistance of a patterned imageable resist prior to patterning an underlying substrate layer is provided. Specifically, the method employed by the present invention comprises applying a layer of an imageable resist to a substrate layer; patterning the layer of imageable resist by removing selective areas thereof; and treating the patterned imageable resist with an atmosphere comprising molecules of a hardening agent so as to obtain a hardened resist surface which etches at a slower rate than that of the untreated resist.
