Method for producing a stamp for hot embossing

Номер: US20120000379A1
Принадлежит: University of Toronto

The present invention provides a process for producing a stamp for hot embossing (HE). The stamp can be constructed from any photo-resist epoxy that is stable at temperatures equal to the glass transition temperature (T g ) of the material to be stamped. The stamp can be used repeatedly without significant distortion of features. The stamp benefits from low relative cost, high fidelity of features in all three-dimensions and fast construction. The process for producing a stamp for hot embossing from a resist, comprising the steps of producing a seed layer L 1 from a selected photoresist polymer material, soft baking the seed layer L 1 , exposing said seed layer L 1 to initiate cross-linking and then post-exposure bake L 1 to fully cross-link it, coating the cross-linked seed layer L 1 with a second photoresist polymer layer L 2 ; soft baking the second photoresist polymer layer L 2 ; applying a mask to the top surface of the soft baked layer L 2 and illuminating the unmasked portions of the soft baked layer L 2 with UV radiation through the mask, wherein the exposed areas form the pattern of the embossing features, washing away un-exposed regions of the photoresist with a developer to leave behind a relief pattern formed in the second photoresist polymer layer L 2 , which relief pattern corresponds to a pattern in the mask.

Nanoelectromechanical Structures Exhibiting Tensile Stress And Techniques For Fabrication Thereof

Номер: US20120286377A1
Принадлежит: International Business Machines Corp

Improved nano-electromechanical system devices and structures and systems and techniques for their fabrication. In one embodiment, a structure comprises an underlying substrate separated from first and second anchor points by first and second insulating support points, respectively. The first and second anchor points are joined by a beam. First and second deposition regions overlie the first and second anchor points, respectively, and the first and second deposition regions exert compression on the first and second anchor points, respectively. The compression on the first and second anchor points causes opposing forces on the beam, subjecting the beam to a tensile stress. The first and second deposition regions suitably exhibit an internal tensile stress having an achievable maximum varying with their thickness, so that the tensile stress exerted on the beam depends at least on part on the thickness of the first and second deposition regions.

Номер: US20120292185A1
Принадлежит: SAMSUNG ELECTRONICS CO LTD

A method of fabricating a liquid film is provided. The method comprises the steps of applying hydrophilic liquid onto a substrate with an electrode formed thereunder, covering the hydrophilic liquid with a protection film comprising hydrophobic liquid, dispersing surfactant for reducing the surface tension between the hydrophilic liquid and the protection film, and applying voltage to the hydrophilic liquid and the electrode to wet the substrate with the hydrophilic liquid. With the surfactant and the electro-wetting principle, a contact angle between the hydrophilic liquid and the substrate is controlled. The liquid film having a uniform thickness in nano size is thus formed on the substrate. The protection film prevents the evaporation of the liquid film in the air to thereby secure the stability of the liquid film.

Method for mems device fabrication and device formed

Номер: US20130299926A1
Принадлежит: Cavendish Kinetics Inc

The present invention generally relates to methods for producing MEMS or NEMS devices and the devices themselves. A thin layer of a material having a lower recombination coefficient as compared to the cantilever structure may be deposited over the cantilever structure, the RF electrode and the pull-off electrode. The thin layer permits the etching gas introduced to the cavity to decrease the overall etchant recombination rate within the cavity and thus, increase the etching rate of the sacrificial material within the cavity. The etchant itself may be introduced through an opening in the encapsulating layer that is linearly aligned with the anchor portion of the cantilever structure so that the topmost layer of sacrificial material is etched first. Thereafter, sealing material may seal the cavity and extend into the cavity all the way to the anchor portion to provide additional strength to the anchor portion.
