    摘要： When an instruction is executed on an integrated circuit (IC), an activity level and temperature are measured. A relationship between the activity level and temperature is determined, to estimate the temperature from the activity level. The activity level is monitored and is input to a scheduler, which estimates the IC temperature based on the activity level. The scheduler distributes work taking into account the temperature of various IC regions and may include distributing work to the IC region that has a lowest estimated temperature or relatively lower estimated temperature (e.g., lower than the average IC or IC region temperature). When the utilization level of one or more IC regions is high, the scheduler is configured to reduce the clock speed or the voltage of the one or more IC regions, or flag the regions as being unavailable for additional workload.

    摘要： A method for fabricating a dynamic random access memory (DRAM) capacitor stack is disclosed wherein the stack includes a first electrode, a dielectric layer, and a second electrode. The first electrode is formed from a conductive binary metal compound and the conductive binary metal compound is annealed in a reducing atmosphere to promote the formation of a desired crystal structure. The binary metal compound may be a metal oxide. Annealing the metal oxide (i.e. molybdenum oxide) in a reducing atmosphere may result in the formation of a first electrode material (i.e. MoO2) with a rutile-phase crystal structure. This facilitates the formation of the rutile-phase crystal structure when TiO2 is used as the dielectric layer. The rutile-phase of TiO2 has a higher k value than the other possible crystal structures of TiO2 resulting in improved performance of the DRAM capacitor.

    摘要： Method and apparatus for making an object. The invention includes the division of a shape of an object into a plurality of layers, and arranging the thickness of the layers based on the curvature of the object to be made. Further, curving edges of the object are replaced with linear sloping edges on the layers. The invention reduces the cost and improves the speed of rapid prototyping, especially with machining methods such as wire electrodischarge machining and laser machining.

    摘要： Various examples provide systems, methods, and computer-readable media for determining manufacturing data based on three-dimensional models. The manufacturing data can include data of outlines of planar models, e.g., corresponding to partitions of the three-dimensional model. Various examples include operating a manufacturing device, e.g., a cutter or mill, to produce physical components based at least in part on the manufacturing data. Various examples include determining the manufacturing data for a partition corresponding to a hollow extrusion of a contour of that partition. Various examples provide user interfaces permitting users to modify parameters of the manufacturing data, e.g., contour shape or extrusion thickness. Various examples permit cutting sheet material into components that can be folded into three-dimensional shapes and assembled into a three-dimensional model.
