摘要:
On a substrate surface, which has been patterned in the form of a relief, of a substrate, typically of a semiconductor wafer, a deposition process is used to provide a covering layer on process surfaces which are vertical or inclined with respect to the substrate surface. The covering layer is patterned in a direction which is vertical with respect to the substrate surface by limiting a process quantity of at least one precursor material and/or by temporarily limiting the deposition process, and is formed as a functional layer or mask for subsequent process steps.

The present invention relates to a method for determining the depth of a buried structure in a semiconductor wafer. According to the invention, the layer behavior of the semiconductor wafer which is brought about by the buried structure when the semiconductor wafer is irradiated with electromagnetic radiation in the infrared range and arises as a result of the significantly longer wavelengths of the radiation used in comparison with the lateral dimensions of the buried structure is utilized to determine the depth of the buried structure by spectrometric and/or ellipsometric methods.

Disclosed are systems and methods for dispensing flavor doses and beverages. A beverage tower may be provided that has a small footprint and that is capable of dispensing a wide variety of flavor doses and blended beverages. The beverage tower may include a flow control module that controls the flow rate of beverage additives and water through the beverage tower and a switch module that includes a plurality of switches that may be selectively opened and closed to control the flow of beverage additives and water through the beverage tower to a point of dispense. A flavor dose or blended beverage may be dispensed by the beverage tower in accordance with user input that is provided to the beverage tower via a control panel. The user input may specify a desired beverage additive, a desired cup size, and an indication of whether a flavor shot or a blended beverage is desired. Additionally, a user may define and program into the memory of the beverage tower the various flavor doses and blended beverages that are capable of being dispensed by the beverage tower.
摘要:
A dielectric barrier layer composed of a metal oxide is applied in thin layers with a thickness of less than 20 nanometers in the course of processing semiconductor devices by sequential gas phase deposition or molecular beam epitaxy in molecular individual layers on differently structured base substrates. The method allows, inter alias, effective conductive diffusion barriers to be formed from a dielectric material, an optimization of the layer thickness of the barrier layer, an increase in the temperature budget for subsequent process steps, and a reduction in the effort for removing the temporary barrier layers.
摘要:
Charge-trapping regions are arranged beneath lower edges of the gate electrode separate from one another. Source/drain regions are formed in self-aligned manner with respect to the charge-trapping regions by means of a doping process at low energy in order to form shallow junctions laterally extending only a small distance beneath the charge-trapping regions. The self-alignment ensures a large number of program-erase cycles with high effectiveness and good data retention, because the locations of the injections of charge carriers of opposite signs are narrowly and exactly defined.
摘要:
A structure on a layer surface of the semiconductor wafer has at least one first area region (8, 9), which is reflective for electromagnetic radiation, and at least one second, essentially nonreflecting area region (10, 11, 12). A light-transmissive insulation layer (13) and a light-sensitive layer are produced on said layer surface. The electromagnetic radiation is directed onto the light-sensitive layer with an angle Θ of incidence and the structure of the layer surface is imaged with a lateral offset into the light-sensitive layer.
摘要:
In a method for forming patterned ceramic layers, a ceramic material is deposited on a substrate and is subsequently densified by heat treatment, for example. In this case, the initially amorphous material is converted into a crystalline or polycrystalline form. In order that the now crystalline material can be removed again from the substrate, imperfections are produced in the ceramic material, for example by ion implantation. As a result, the etching medium can more easily attack the ceramic material, so that the latter can be removed with a higher etching rate. Through inclined implantation, the method can be performed in a self-aligning manner and the ceramic material can be removed on one side, by way of example, in trenches or deep trench capacitors.
摘要:
A process for modifying sections of a semiconductor includes covering the sections to remain free of doping with a metal oxide, e.g., aluminum oxide. Then, the semiconductor is doped, for example, from the gas phase, in those sections that are not covered by the aluminum oxide. Finally, the aluminum oxide is selectively removed again, for example using hot phosphoric acid. Sections of the semiconductor surface which are formed from silicon, silicon oxide or silicon nitride remain in place on the wafer.
