This invention discloses an improved trenched metal oxide semiconductor field effect transistor (MOSFET) device that includes a trenched gate surrounded by a source region encompassed in a body region above a drain region disposed on a bottom surface of a substrate. The MOSFET cell further includes a shielded gate trench (SGT) structure below and insulated from the trenched gate. The SGT structure is formed substantially as a round hole having a lateral expansion extended beyond the trench gate and covered by a dielectric linen layer filled with a trenched gate material. The round hole is formed by an isotropic etch at the bottom of the trenched gate and is insulated from the trenched gate by an oxide insulation layer. The round hole has a lateral expansion beyond the trench walls and the lateral expansion serves as a vertical alignment landmark for controlling the depth of the trenched gate. The MOSFET device has a reduced gate to drain capacitance Cgd depending on the controllable depth of the trenched gate disposed above the SGT structure formed as a round hole below the trenched gate.

The present invention provides devices and methods for the treatment of cardiovascular valve diseases such as aortic stenosis. A vascular valve assembly is formed from two or more valve devices, each of which contains a valve mounted in a stent. The individual valve devices are brought to the site of the defective valve by standard percutaneous catheterization methods. Lateral expansion of the stents at the site of valve replacement produces a functioning valve assembly. Appropriate sizing and number of valve devices prevents regurgitation and migration. The assembly of two or more smaller valve devices at the site of a defective valve prevents complications due to the large size of single valve prostheses.

Method of limiting the lateral extent of a trench capacitor by a dielectric spacer in a hybrid orientations substrate is provided. The dielectric spacer separates a top semiconductor portion from an epitaxially regrown portion, which have different crystallographic orientations. The deep trench is formed as a substantially straight trench within the epitaxially regrown portion such that part of the epitaxially regrown portion remains overlying the dielectric spacer. The substantially straight trench is then laterally expanded to form a bottle shaped trench and to provide increased capacitance. The lateral expansion of the deep trench is self-limited by the dielectric spacer above the interface between the handle substrate and the buried insulator layer. During subsequent formation of a doped buried plate, the dielectric spacer blocks diffusion of dopants into the top semiconductor portion, providing a compact bottle shaped trench capacitor having high capacitance without introducing dopants into the top semiconductor portion.

The invention relates to a construction method of a blasthole stemming structure for drilling blasting and a concrete block structure for the method. The blasthole stemming structure comprises a cylindrical-conical reinforcement built-in concrete block structure, a buffer section and a rock ballast filling body meeting certain grain size requirements, wherein one end of the cylindrical-conical reinforcement built-in concrete block structure is conical while the other end is cylindrical.
