摘要:
A method for manufacturing a semiconductor device that comprises forming an oxide layer over a substrate. A polysilicon layer is disposed outwardly from the oxide layer, wherein the polysilicon layer forms a floating gate. A PSG layer is disposed outwardly from the polysilicon layer and planarized. The device is pattern etched to form a capacitor channel, wherein the capacitor channel is disposed substantially above the floating gate formed from the polysilicon layer. A dielectric layer is formed in the capacitor channel disposed outwardly from the polysilicon layer. A tungsten plug operable to substantially fill the capacitor channel is formed.

An apparatus and method is provided to dry veneer or other items by vaporization of moisture in the item. Apparatus has an insulated chamber with a frame and a drawer with a door. A mesh surface of the drawer supports item for drying with a heater at sub-atmospheric pressure inside of the chamber. Item is placed on the layer of mesh of the drawer of the apparatus and secured with fasteners such as another layer of mesh. The drawer with fastened item is placed into the chamber of the apparatus. With the drawer fully engaged within the chamber, the drying apparatus is closed with an airtight seal. A pump draws a vacuum in the chamber and heat is directed at the item to raise the temperature of the item to less than 160° F., particularly between 120° F. to 150° F. Apparatus can dry veneer in less than five minutes.

Transgenic seed for crops with improved traits are provided by trait-improving recombinant DNA where plants grown from such transgenic seed exhibit one or more improved traits as compared to a control plant. Of particular interest are transgenic plants that have increased yield. The present invention also provides recombinant DNA molecules for expression of a protein, and recombinant DNA molecules for expression of mRNA complementary to at least a portion of an mRNA native to the target plant for use in gene suppression to suppress the expression of a protein.

The present invention relates to a method for forming an anlog capacitor on a semiconductor substrate. The method comprises forming a field oxide over a portion of the substrate, and forming a polysilicon layer over the field oxide layer, and subsequently forming a silicide over the polysilicon layer. A first interlayer dielectric layer is formed over the substrate, and a capacitor masking pattern is formed. The first interlayer dielectric is etched using the capacitor masking pattern as a mask and the silicide layer as an etch stop, and a thin dielectric is formed over the substrate. A contact masking pattern is formed over the substrate, and a subsequent etch is performed on the thin dielectric and the first interlayer dielectric using the silicide and substrate as an etch stop. A metal layer is deposited over the substrate, and is subsequently planarized, thereby defining an analog capacitor.
