Abstract:
The present disclosure provides for many different embodiments of a charged particle beam data storage system and method. In an example, a method includes dividing a design layout into a plurality of units; creating a lookup table that maps each of the plurality of units to its position within the design layout and a data set, wherein the lookup table associates any repeating units in the plurality of units to a same data set; and exposing an energy sensitive layer to a charged particle beam based on the lookup table.
Abstract:
A planarization method of manufacturing a semiconductor component is provided. A dielectric layer is formed above a substrate and defines a trench therein. A barrier layer and a metal layer are formed in sequence in the trench. A first planarization process is applied to the metal layer by using a first reactant so that a portion of the metal layer is removed. An etching rate of the first reactant to the metal layer is greater than that of the first reactant to the barrier layer. A second planarization process is applied to the barrier layer and the metal layer by using a second reactant so that a portion of the barrier layer and the metal layer are removed to expose the dielectric layer. An etching rate of the second reactant to the barrier layer is greater than that of the second reactant to the metal layer.
Abstract:
An image correction apparatus for correcting an original image captured by a photographing device is provided. The image correction apparatus includes a storage and a texture mapping module. The storage therein stores mapping data sets associated with the photographing device. The invention is able to construct and utilize mapping data associated with a particular optical lens when used as part of the photographic device. The texture mapping module corrects an original captured image using a texture mapping procedure according to the appropriate mapping data to generate a corrected image. The texture mapping procedure may use mapping data in a polygon based approach to generate corrected images more efficiently.

Abstract:
A full-zone optical image addressing apparatus, including an addressing device, an image extraction converter, a comparator, an AND gate and a counter. The addressing device is located at the enclosure of the scanner and includes a plurality of geometric patterns. Each of the geometric patterns includes a plurality of rows of pixels. While receiving an exposure signal, the image extraction converter extracts one row of pixels from the addressing device, such that a series of analog signals is obtained and output to the comparator. The comparator then compares the series of analog signals to an analog critical voltage to output a series of analog comparison signals to the AND gate. The AND gate synchronously processes the series of analog comparison signals and a pixel rate clock to output the pixel data corresponding to the extracted row of pixels to the counter. After receiving the synchronously processed pixel value from the AND gate, the counter calculates and outputs the extracted row of pixels, including the amount of pixels and the geometric patterns in the row of pixels.
Abstract:
Provided is a method of fabricating a semiconductor device that includes forming first and second fins over first and second regions of a substrate, forming first and second gate structures over the first and second fins, the first and second gate structures including first and second poly gates, forming an inter-level dielectric (ILD) over the substrate, performing a chemical mechanical polishing on the ILD to expose the first and second poly gates, forming a mask to protect the first poly gate of the first gate structure, removing the second poly gate thereby forming a first trench, removing the mask, partially removing the first poly gate thereby forming a second trench, forming a work function metal layer partially filling the first and second trenches, forming a fill metal layer filling a remainder of the first and second trenches, and removing the metal layers outside the first and second trenches.
Abstract:
Provided is a high-k metal gate structure formed over a semiconductor fin. A nitride layer is formed over the gate structure and the semiconductor fin, using two separate deposition operations, the first forming a very thin nitride film. Implantation operations such as an LDD or a PKT implant, are carried out in between the two nitride film deposition operations. The first nitride film may be SiN, or SiCNx and the second nitride film is SiCNx with a low wet etch rate in H3PO4 and dilute HF acid. The nitride films may be combined to form low wet etch rate spacers enabling further processing operations to be carried out without damaging underlying structures and without requiring the formation of further dummy spacers. Further processing operations include epitaxial silicon/SiGe processing sequences and source/drain implanting operations carried out with the low etch rate spacers intact.

Abstract:
A method for monitoring a manufacturing process features acquiring metrology data for semiconductor wafers at the conclusion of a final process step for the manufacturing process (“Step a”). Data is acquired for a plurality of process variables for a first process step for manufacturing semiconductor wafers (“Step b”). A first mathematical model of the first process step is created based on the metrology data and the acquired data for the plurality of process variables for the first process step (“Step c”). Steps b and c are repeated for at least a second process step for manufacturing the semiconductor wafers (“Step d”). An nth mathematical model is created based on the metrology data and the data for the plurality of process variables for each of the n process steps ('Step e“). A top level mathematical model is created based on the metrology data and the models created by steps c, d and e (”Step f'). The top level mathematical model of Step f is based on those process variables that have a substantial effect on the metrology data.
