• Contribution to field (領域的貢獻)



範例 (第部分:背景)

研究建構 Increasingly larger substrate requirements have spurred advances in

semiconductor manufacturing, explaining the increasing importance of the pumping

performance of vacuum pumps in etching, chemical vapor deposition (CVD), and

physical vapor deposition (PVD) to satisfy ultraclean environment requirements. However,

using oil-free backing pumps in combination with the turbomolecular pump (TMP) to

satisfy ultraclean environment requirements is problematic. The TMP compound includes

the addition of a turbodrag section to the conventional TMP stage in the same rotationshaft in order to ensure that the discharge pressure ranges between 7.5 and 15 Torr.

Levi (1992) also pioneered the use of hybrid pumps, which uses a variety of impellers

without increasing the number of stages on the same axis. Notably, the conventionally

adopted TMP uses momentum transfers from high-speed rotating blades to the gas

molecules for pumping gas. According to the direction of the pumped fluid to the

movement of the moving wall, the TMP is perpendicular to the movement of the moving

wall; otherwise, the molecular drag pump (MDP) is parallel. The MDP can operate in the

7.5x-3 Torr-7.5 x-2 Torr at a full pumping speed owing to a high compression ration in the

viscous flow regime, which is infeasible for a molecular flow regime.



範例 (第部分:背景)

研究問題 The CVD and etching equipment in the IC industry require superiordischarge pressures from the atmosphere to a high-vacuum region. Among themany subsequent design types include those of Becker, Siegbahn, Holwek,and Gaede. Although these designs normally increase either the pumpingspeed or compression ratio, increasing the pumping speed and compressionsimultaneously (especially in higher discharge pressures) is problematic owingto the complex transition flow phenomena. Additionally, the processingpressure can not remain constant with a declining pumping performance.

研究問題的量化 A typical TMP typically has many stages for optimizing thepumping speed and compression ratio, resulting in different compression ratios,especially the lower value for light gases. Moreover, the compression ratios arehigh at discharge pressures lower than 7.5x-3 Torr. However, the pumpingspeed obviously declines at higher discharge pressures.

研究問題的中心 Ultimately, the pumping performances of TMP lower itsefficiency as the distance of blades becomes comparable to the mean free pathof gas molecules.



範例 (第二部分:行動)

研究目標 Based on the above, we should develop avacuum performance system (based on OR according to)ISO standards with automatic testing and human-machineinterface functions.

達成目標的方法 To do so, pumping performances can beevaluated based on the flow meter method. The flow ratecan then be adjusted to obtain a balanced inlet pressure.Next, the pumping speed based on the difference of inletpressure and ultimate pressure can be divided by thethroughput. Additionally, results of the experimental pumpingspeed can be compared with those of the simulations.



範例 (第二部分:行動)

希望的結果 As anticipated, the proposed vacuumperformance system can evaluate the throughput, pumpingspeed, ultimate pressure, and residue gas analysis via itsautomatic testing and human-machine interface functions inan inlet pressure exceeding 1.3x10-6 Torr.

領域的貢獻 Importantly, the proposed system can providedesired characteristics such as ultimate pressure,compression ratio, and pumping speed, ultimatelyeliminating the evaluated time and providing human-machineinterface functions.



範例二(第部分:背景)

研究建構 Industrial development has led to the extensive

use of plastic products in daily life, with polymers like

polyvinyl alcohol (PVA), polyethylene (PE), or

polypropylene (PP), as an increasingly common source of

related industrial applications. For instance, PVA iscommonly adopted in the textile and paper-making

industries.

研究問題 However, similar to other polymers, the difficulty

of PVA degradation reflects the complexity of handling it

during industrial wastewater treatment.



範例二(第部分:背景)

研究問題的量化 Despite the numerous chemical andbiological treatment methods developed for PVAdegradation and their promising results, such methodshave certain limitations, including too long of a reactiontime and pollution caused by biological or chemical

reactants. While investigating mixed cultures acclimatizedto PVA solution, Solaro et al. indicated only 40%mineralization of PVA after 48 days of incubation.

Additionally, use of Fenton reaction to reduce PVA wasrevealed that after 2 hours of reaction time, the PVA

removal rate reached only 40%.研究問題的中心 The inability to degrade PVA adequatelythrough wastewater treatment will result in PVA enteringthe public water supply and flowing into the sea, ultimatelythreatening humans and the surrounding ecology.



範例二(第二部分:行動)

研究目標 Based on the above, we should develop anefficient and environmentally friendly PVA-basedwastewater treatment method that does not produce otherby-products or harmful waste.

達成目標的方法 To do so, PVA can be degraded efficientlyby photocatalysis. The removal efficiency of PVA can thenbe examined based on the reaction temperature, PVAconcentration, and photocatalytic quantity. Next, analysisresults of the proposed wastewater treatment method canbe compared with those of previous methods.



範例二(第二部分:行動)

希望的結果 As anticipated, the photocatalysis ofthe proposed wastewater treatment method candegrade PVA contents completely in two hours.

領域的貢獻 In addition to its photocatalysiscapability to degrade PVA efficiently, the proposedmethod provides a valuable reference for researchin other industrial applications such asdecomposing polymers in a sewage treatment

plant.
