It is provided a method of designing at least one oligonucleotide for nucleic acid detection comprising the following steps in any order: (I) identifying and/or selecting region(s) of at least one target nucleic acid to be amplified, the region(s) having an efficiency of amplification (AE) higher than the average AE; and (II) designing at least one oligonucleotide capable of hybridizing to the selected region(s). It is also provided a method of detecting at least one target nucleic acid comprising the steps of: (i) providing at least one biological sample; (ii) amplifying nucleic acid(s) comprised in the biological sample; (iii) providing at least one oligonucleotide capable of hybridizing to at least one target nucleic acid, if present in the biological sample; and (iv) contacting the oligonucleotide(s) with the amplified nucleic acids and detecting the oligonucleotide(s) hybridized to the target nucleic acid(s). In particular, the method is for detecting the presence of at least one pathogen, for example a virus, in at least one human biological sample. The probes may be placed on a support, for example a microarray.

摘要:
A two-step stripping method for removing via photoresist during the fabrication of trench-first partial-via dual damascene features is disclosed. In the first cleaning step, inert gas (He, Ar, N2)/fluorocarbon plasma is used to contact the remaining “Via Photo” for a short time period not exceeding 20 seconds. Thereafter, in the second cleaning step, a reducing plasma is used to completely strip the remaining “Via Photo”, thereby preventing the low-k or ultra low-k carbon-containing dielectric layer from potential carbon depletion.

摘要:
Provided is a method for increasing an etching selectivity of photoresist material. The method initiates with providing a substrate with a developed photoresist layer. The developed photoresist layer on the substrate is formulated to contain a hardening agent. Next, the substrate is exposed to a gas, where the gas is formulated to interact with the hardening agent. A portion of the developed photoresist layer is then converted to a hardened layer where the hardened layer is created by an interaction of the hardening agent with the gas. Some notable advantages of the discussed methods of increasing the selectivity of a photoresist include improved etch profile control. Additionally, by combining fabrication steps such as the hardening of the photoresist in an etch chamber, downstream etching processes may be performed without having to transfer the wafer to an additional chamber, thereby improving wafer throughput while minimizing handling.
摘要:
Apparatus and associated methods relate to a wireless audio speaker module configured to play music at a volume level that will not disturb those nearby, based on adapting a wireless audio speaker to be retained within headgear, adjusting the volume of sound emitted by the speaker to a level that will not disturb those nearby, and amplifying the speaker sound as a function of the headgear interior reflecting the sound emitted by the speaker to the user's ear. In an illustrative example, an airgap may be configured between the speaker and the headgear user's ear. In various embodiments, the sound volume emitted by the speaker may be adjusted to avoid disturbing those nearby. In some examples, the headgear may be a hardhat, advantageously configured with a wireless audio speaker module to permit construction workers to listen to music amplified by reflection within their hardhats without disturbing or distracting each other.

摘要:
A real-time billing monitoring system and method. A processor receiving time data with respect to a task. The time data measures an amount of work accruing by one or more staff members toward completion of the task as the task is being performed. The processor generates a graphical object representing the time data as the task is being performed. The object is displayed on a display device concurrently with the performance of the task.

Provided is a method and apparatus for increasing an etching selectivity of photoresist material. An exemplary method initiates with providing a substrate with a developed photoresist layer. The developed photoresist layer on the substrate includes polymer chains containing silicon. Next, the substrate and developed photoresist layer are exposed to an ultraviolet (UV) light, where the UV light emanates from a UV generating agent. A portion of the developed photoresist layer is then converted to a hardened layer where the hardened layer is created by cross-linking the polymer chains containing silicon and the cross-linking is activated by the UV light. Next an etch may be performed on the substrate using the hardened layer.
