摘要:
A trench DMOS transistor with a very low on-state drain-to-source resistance and a high gate-to-drain charge includes one or more floating islands that lie between the gate and drain to reduce the charge coupling between the gate and drain, and effectively lower the gate-to-drain capacitance.

摘要:
In one aspect, there is provided a method of manufacturing a semiconductor device. The method comprises depositing a barrier layer over a low-k dielectric layer located over a semiconductor substrate over which a metal layer is deposited. A chemical mechanical polish process is used to remove a portion of the metal layer and the barrier layer and a dry etch is used to remove a remaining portion of the barrier layer.
摘要:
A chemical mechanical polishing pad and method for chemical-mechanical polishing is provided, wherein the polishing pad has a plurality of first mesas and one or more second mesas defined on a surface thereof. The plurality of first mesas are generally distributed about the surface of the polishing pad, wherein each of the plurality of first mesas has a first surface area associated therewith. The one or more second mesas are associated with a center region of the polishing pad, wherein each of the one or more second mesas has a second surface area associated therewith. The second surface area is at least twice the first surface area.
摘要:
The present invention relates to a method for performing chemical mechanical polishing. A high down-force step is performed. A low down-force step is performed. At least one of the down-force steps is modified, based on if one of the down-force steps exceeds an acceptable tolerance associated therewith. Other systems and methods are also disclosed.

Also, a method to eliminate the copper corrosion of copper interconnects by forming 70 at least one conductive displacement plating layer on the copper interconnects.
摘要:
Wafer order is randomized in-situ by use of a separate wafer staging area and randomly shuffling wafers to and from this staging area to shuffle the processing order of the wafer lot. Positional data is captured for each wafer at both the send and receive ends of the process.
摘要:
A method is disclosed for eliminating a mask layer during the manufacture of thin film resistor circuits. The method of the present invention enables the simultaneous etching of both deep vias and shallow vias using one mask layer instead of two mask layers. A high selectivity film layer of silicon nitride is formed on the ends of a thin film resistor layer. The thickness of the silicon nitride causes the etch time for a shallow via to the thin film resistor to be approximately equal to an etch time for a deep via that is etched through dielectric material to an underlying patterned metal layer.
摘要:
A method for measuring the step height of a STI structure is described. The method involves measuring the change in resistance of a polysilicon structure as the step height changes. The resistance of the polysilicon structure is measured by applying a voltage and measuring the resulting current.
