Abstract: Exemplary semiconductor processing methods may include performing a pre-treatment on a substrate housed within a processing region of a semiconductor processing chamber. The substrate may include a layer of silicon-and-carbon-containing material. The pre-treatment may remove native oxide or residue from a surface of the layer of silicon-and-carbon-containing material. The methods may include providing a silicon-containing precursor to the processing region of the semiconductor processing chamber. The methods may include contacting the substrate with the silicon-containing precursor. The contacting may deposit a layer of silicon-containing material on the layer of silicon-and-carbon-containing material. The methods may include providing an oxygen-containing precursor to the processing region of the semiconductor processing chamber. The methods may include contacting the substrate with the oxygen-containing precursor.

The structures may also include an electrode material deposited overlying the second layer.

Abstract: A super junction device with an increased voltage rating may be formed by decreasing the width of the P-type region and increasing the doping concentration, while also increasing the height of the overall device. However, instead of etching a trench in the N-type material to fill with the P-type material, a trench may be etched for both the P-type region and an adjacent N-type region. This allows the height of the overall device to be increased while maintaining a feasible aspect ratio for the trench. The P-type material may then be formed as a sidewall liner on the trench that is relatively thin compared to the remaining width of the trench. The trench may then be filled with N-type material such that the P-type region fills the space between the N-type regions without any voids or seams, while having a width that would be unattainable using traditional etch-and-fill methods for the P-type region alone.

Abstract: A super junction device with an increased manufacturing throughput may be formed by forming narrow trenches lined with a P-type liner and rapidly filled with a passive fill material. Instead of etching trenches with aspect ratio large enough to reliably fill with doped P-type material, the aspect ratio of the trench may be reduced to shrink the size of the device. This smaller trench may then be lined with a relatively thin (e.g., about 1 ?m to about 2 ?m) P-type liner instead of completely filling the trench with P-type material. Inside the P-type liner, the trench may then be filled with a passive fill material. Filling the trench with the passive fill material may be carried out in a matter of minutes at relatively high temperatures, thereby likely causing a void or seam to form within the passive fill material. However, because the passive fill material does not affect the operation of the device, this type of defect can exist in the device.

Abstract: A silicon carbide transistor may be formed with a channel that includes a p-doped region between n-doped source and drain regions. A counter-doped region may be formed at the top of the channel directly underneath the gate oxide. Instead of using the conventional doping levels for the p-doped region, the doping concentration may be increase to be greater than about 1e18 cm3. The transistor may also include pocket regions on one or both sides of the channel. The pocket regions may be formed in the counter-doped region and may extend up to the gate oxide. These improvements individually and/or in combination may increase the current in the channel of the transistor without significantly increasing the threshold voltage beyond acceptable operating limits.

The method comprises patterning a substrate to form a first opening and a second opening, the substrate comprising an n transistor and a p transistor, the first opening over the n transistor and the second opening over the p transistor; pre-cleaning the substrate; depositing a titanium silicide (TiSi) layer on the n transistor and on the p transistor by plasma-enhanced chemical vapor deposition (PECVD); optionally depositing a first barrier layer on the titanium silicide (TiSi) layer and selectively removing the first barrier layer from the p transistor; selectively forming a molybdenum silicide (MoSi) layer on the titanium silicide (TiSi) layer on the n transistor and the p transistor; forming a second barrier layer on the molybdenum silicide (MoSi) layer; and annealing the semiconductor structure. The method may be performed in a processing chamber without breaking vacuum.

Abstract: A method of correcting bias temperature instability in memory arrays may include applying a first bias to a memory cell, where the memory cell may include a memory element and a select element, and the first bias may causes a value to be stored in the memory element. The first bias causes a bias temperature instability (BTI) associated with the memory cell to increase. The method may also include applying a second bias to the memory cell, where the second bias may have a polarity that is opposite of the first bias, and the value stored in the memory element remains in the memory element after the second bias is applied. The second bias may also cause the BTI associated with the memory cell to decrease while maintaining any value stored in the memory cell.

Abstract: A method for setting memory elements in a plurality of states includes applying a set signal to a memory element to transition the memory element from a low-current state to a high-current state; applying a partial reset signal to the memory element to transition the memory element from the high-current state to a state between the high-current state and the low-current state; determining whether the state corresponds to a predetermined state; and applying one or more additional partial reset signals to the memory element until the state corresponds to the predetermined current state. The memory element may be coupled in series with a transistor, and a voltage control circuit may apply voltages to the transistor to set and partially reset the memory element.
