A quick assembly and disassembly structure of a toilet seat base, including a supporting base, base boards, lid bodies, and axial hole portions and connecting portions on the supporting base; each connecting portion is provided with a sliding groove; each base board is slidable back and forth within a corresponding sliding groove and non-movable vertically within the corresponding sliding groove; one end of each lid body is pivotally connected with a corresponding connecting portion; a bottom surface of each lid body is provided with positioning ribs; a top surface of each connecting portion is provided with positioning holes; the positioning holes of each connecting portion are in communication to a corresponding sliding groove. When each lid body is closed, the positioning ribs pass through the positioning holes and fit with the positioning grooves, so that each base board and a corresponding sliding groove are fixed.

A method for forming silicide contacts includes forming a dielectric layer on a gate spacer, a gate stack, and a first semiconductor layer. The first semiconductor layer comprises source/drain regions. Contact trenches are formed in the dielectric layer so as to expose at least a portion of the source/drain regions. A second semiconductor layer is formed within the contact trenches. A metallic layer is formed on the second semiconductor layer. An anneal is performed to form a silicide region between the second semiconductor layer and the metallic layer. A conductive contact layer is formed on the metallic layer or the silicide region.

Methods and devices are provided for fabricating a semiconductor device having barrier regions within regions of insulating material resulting in outgassing paths from the regions of insulating material. A method comprises forming a barrier region within an insulating material proximate the isolated region of semiconductor material and forming a gate structure overlying the isolated region of semiconductor material. The barrier region is adjacent to the isolated region of semiconductor material, resulting in an outgassing path within the insulating material.

A diaphragm is disclosed. The diaphragm includes a vibrating member, a projection extruding from a periphery of the vibrating member, a supporting member surrounding the vibrating member. A first gap is formed between the vibrating member and the supporting member. The supporting member includes a supporting girder surrounding and separated from the projection. A torsion girder is connected to the projection and a fixing girder is parallel to the torsion girder. A second gap is defined between the fixing girder and the torsion girder.

Disclosed is a diaphragm includes a vibrating member, a plurality of supporting members extending from a periphery of the vibrating member along a direction away from a center of the diaphragm, and a plurality of separating portions each located between two adjacent supporting members. Each of the supporting members defines a first beam, a second beam, and at least one slit between the first and second beams.

A double-effective vaccine vector against foot-and-mouth disease virus having a bicistronic expression vector sequence, the bicistronic expression vector sequence is an antisense gene sequence capable of conjugating with 5′ UTR of RNA of the foot-and-mouth disease virus genome and an intact sequence of VP1 structural protein gene of the foot-and-mouth disease virus. Animal experiments show that the vaccine vector provides double effects in terms of gene therapy and gene immunization for the prevention and treatment of foot-and-mouth disease in animals. Also provided are construction methods and methods of use of the vaccine vector.
摘要:
A fabrication method for a semiconductor device structure is provided. The device structure has a layer of silicon and a layer of silicon dioxide overlying the layer of silicon, and the method begins by forming an isolation recess by removing a portion of the silicon dioxide and a portion of the silicon. The isolation recess is filled with stress-inducing silicon nitride and, thereafter, the silicon dioxide is removed such that the stress-inducing silicon nitride protrudes above the silicon. Next, the exposed silicon is thermally oxidized to form silicon dioxide hardmask material overlying the silicon. Thereafter, a first portion of the silicon dioxide hardmask material is removed to reveal an accessible surface of the silicon, while leaving a second portion of the silicon dioxide hardmask material intact. Next, silicon germanium is epitaxially grown from the accessible surface of the silicon.
