    Abstract: A method of making a lead frame and a partially patterned lead frame package with near-chip scale packaging (CSP) lead-counts is disclosed, wherein the method lends itself to better automation of the manufacturing line as well as to improving the quality and reliability of the packages produced therefrom. This is accomplished by performing a major portion of the manufacturing process steps with a partially patterned strip of metal formed into a web-like lead frame on one side, in contrast with the conventional fully etched stencil-like lead frames, so that the web-like lead frame, which is solid and flat on the other side is also rigid mechanically and robust thermally to perform without distortion or deformation during the chip-attach and wire bond processes, both at the chip level and the package level. The bottom side of the metal lead frame is patterned to isolate the chip-pad and the wire bond contacts only after the front side, including the chip and wires, is hermetically sealed with an encapsulant.

    Abstract: Elements in a triple-well MOS transistor are prevented from being destroyed due to an increase in current consumption or a thermal runaway of a parasitic bipolar transistor. A triple-well NMOS transistor comprising a P well area formed within an N well area and a MOSFET formed in the P well area, an impurity-diffused area having a lower impurity concentration than an N+ drain area is formed close to the N+ drain area, thereby restraining substrate current. The impurity concentration of the P well area is increased to reduce the current gain of a parasitic bipolar transistor. To further reduce the current gain, a punch-through stopper area may be formed. The impurity concentration of the impurity-diffused area is set to equal that of an N− LDD area 31 of a fine CMOS device integrated on the same substrate 1. These areas are formed during a single ion injection step.

    Abstract: A method of forming shallow trench isolation that reduces junction leakage at the boundary of shallow trench isolation and contact metallurgy of adjacent transistors and that avoids a reduction of carrier concentration in the source and drain region of transistors adjacent to the shallow trench isolation is described. The method to form a shallow trench isolation feature begins by providing a semiconductor substrate having a surface coated with at least one layer of an insulating material and a plurality of shallow trenches formed in the surface of the semiconductor substrate. A nitrogen doped insulating layer is then grown on the internal surfaces or sidewalls of the shallow trenches.

    Abstract: The present invention is a method and structure for fabricating a trench capacitor within a semiconductor substrate having a buried plate electrode formed of metal silicide. A collar is formed in a trench etched into a substrate; a conformal metal film is deposited thereover, and is annealed to form a silicide that is self-aligned to the collar. Silicide will not be formed on the collar, pads and other areas where the silicon is not directly exposed and hence the metal layer can be removed from these areas by selective etching.

  • Publication number: 20030207540
    Abstract: A dielectric film containing LaAlO3 and method of fabricating a dielectric film contained LaAlO3 produce a reliable gate dielectric having a thinner equivalent oxide thickness than attainable using SiO2. The LaAlO3 gate dielectrics formed are thermodynamically stable such that these gate dielectrics will have minimal reactions with a silicon substrate or other structures during processing. A LaAlO3 gate dielectric is formed by atomic layer deposition employing a lanthanum sequence and an aluminum sequence. A lanthanum sequence uses La(thd)3 (thd=2,2,6,6-tetramethl-3,5-heptanedione) and ozone. An aluminum sequence uses either trimethylaluminium, Al(CH3)3, or DMEAA, an adduct of alane (AlH3) and dimethylehtylamine [N(CH3)2(C2H5)], with distilled water vapor.
