Abstract: A crystal growth doping apparatus and a crystal growth doping method are provided. The crystal growth doping apparatus includes a crystal growth furnace and a doping device that includes a feeding tube inserted to the furnace body along an oblique insertion direction, and a storage cover and a gate tube that are disposed in the feeding tube. The feeding tube extends from an outer surface thereof to form a placement opening, and the placement opening is recessed from an edge thereof to form an upper recessed portion and a lower recessed portion along the oblique insertion direction. The storage cover includes a storage tank and a handle. When the storage cover is disposed in the gate tube body, the gate tube body is configured to isolate an inner space of the feeding tube from the placement opening.

Abstract: A single-poly two-transistor PMOS memory cell for multiple-time programming applications includes a PMOS floating gate transistor sharing a drain/source P+ diffusion region with a PMOS select gate transistor all formed within a first n-well. A control plate for the floating gate transistor is formed in a second n-well. A single-poly two-transitor PMOS memory cell for one-time programming applications includes a PMOS floating gate transistor having a source formed as a p+ diffusion region in a single n-well. The source is adapted to also serve as control plate for the floating gate transistor.

Abstract: A method for forming contacts in a semiconductor device including a plurality of active devices formed over a substrate that includes depositing a first layer of dielectric material over the substrate and plurality of active devices, forming a first opening in the first layer of dielectric material, depositing a second layer of dielectric material over the first layer of dielectric material and in the first opening, providing a mask over the second layer of dielectric material, wherein the mask material is distinguishable over silicon oxides, and forming a second opening and a third opening in the second layer of dielectric material, wherein the second opening is aligned with the first opening and exposes a first silicide of a first active device, and the third opening exposes one of diffused regions of a second active device.

Abstract: A method of improving planarity of a photoresist. Before coating the photoresist over a silicon oxide layer, modifying a surface of the silicon oxide layer to enhance an adhesion between the silicon oxide layer and the photoresist. The photoresist flows into trenches of the silicon oxide layer, then the photoresist has good planarity, even after performing a baking process.
