Using IoT technology for computer-integrated manufacturing systems in the semiconductor industry

The evolution of semiconductor manufacturing between lot and equipment has an increasingly complex relationship in the track-in/track-out process mechanism. Failure of reading or updating barcodes may cause some lots to scrap with mis-operation. In this paper, it proposed an Internet of Things (IoT) based Computer-Integrated Manufacturing (CIM) system used in Feature Advantage Benefit (FAB), that semiconductor company used Radio Frequency Identification (RFID) into 300-mm (FAB), and according to the information provided by the semiconductor company MTB (Manufacturing Technical Board). This solution to change the operation process flow to fit the CIM system characteristics of Fab in Manufacturing Execution System (MES). It also use IoT design strategy and the system architecture of this new IoT solution. The result of this research is to incorporate deep learning method in the IoT system into the current CIM system to reveal the benefits in FAB. It estimate to save about US$ 2.8M by adopting IoT RFID instead of tagging to identify a work in process lot in the initiation phase. The company can gain greater asset visibility, reduce the costs of man-power requirements and connect with the worldwide trend.

A MEMS Gyroscope Noise Suppressing Method Using Neural Architecture Search Neural Network

Inertial measurement unit (IMU) (an IMU usually contains three gyroscopes and accelerometers) is the key sensor to construct a self-contained inertial navigation system (INS). IMU manufactured through the Micromechanics Electronics Manufacturing System (MEMS) technology becomes more popular, due to its smaller column, lower cost, and gradually improved accuracy. However, limited by the manufacturing technology, the MEMS IMU raw measurement signals experience complicated noises, which cause the INS navigation solution errors diverge dramatically over time. For addressing this problem, an advanced Neural Architecture Search Recurrent Neural Network (NAS-RNN) was employed in the MEMS gyroscope noise suppressing. NAS-RNN was the recently invented artificial intelligence method for time series problems in data science community. Different from conventional method, NAS-RNN was able to search a more feasible architecture for selected application. In this paper, a popular MEMS IMU STIM300 was employed in the testing experiment, and the sampling frequency was 125 Hz. The experiment results showed that the NAS-RNN was effective for MEMS gyroscope denoising; the standard deviation values of denoised three-axis gyroscope measurements decreased by 44.0%, 34.1%, and 39.3%, respectively. Compared with the Long Short-Term Memory Recurrent Neural Network (LSTM-RNN), the NAS-RNN obtained further decreases by 28.6%, 3.7%, and 8.8% in standard deviation (STD) values of the signals. In addition, the attitude errors decreased by 26.5%, 20.8%, and 16.4% while substituting the LSTM-RNN with the NAS-RNN.

A zero-shot learning method for fault diagnosis under unknown working loads

Data-based fault diagnosis is an important technology in modern manufacturing systems. However, most of these diagnosis methods assume that all the data should be identically distributed. In diagnosis tasks, this assumption means that these methods can only handle faults from the same working load. In real-world applications, the working load of the equipment varies for the different productions; if an unknown working load with no prior data available is given, then these traditional methods may be invalid. Zero-shot learning, using known data to diagnose the fault under unknown working loads, provides a transfer approach to solve this problem. In this paper, a zero-shot learning method based on contractive stacked autoencoders is proposed. The proposed method is only trained by the data from the known working load and can diagnose the fault from unknown but related working loads without prior data. The experimental results on the Case Western Reserve University dataset indicate that the proposed method performs better than the traditional methods under unknown working loads and has an accuracy of 97.82%. In addition, the analysis of the singular value and feature space also suggests that the proposed method is more robust and the feature representation is more contractive.

The model is made with aid of modern Digital Factory tools. The main purpose of the model is to provide a complex tool for this study in order to analyze and optimize the fictive production system in needed range and complexity. The topic of Rapid Prototyping and Additive manufacturing technologies is very recent topic in industry. But still, there are only few examples of production systems, which are really using Rapid Prototyping technologies as a part of the production or production line. The advantage of these technologies is their versatility, but on the other hand, as a part of production system, they can have different demands on for example production planning, area consumption or maintenance, that can affect whole production system.

A Stepping Microrobot Controlled by Flow Oscillations

A self-locomotive microrobot can be a key technology for medical applications, manufacturing, or micro total analysis systems (μTAS). Although previous studies have mostly used magnetic, electric, chemical, or optical forces to control microrobots, we utilized flow oscillations. The results showed that the locomotion of the microrobot was stepwise near a wall when the oscillations were applied both horizontally and vertically. The most efficient microrobot was capable of propelling itself about 2×10-3 times its radius during one oscillation period. These results illustrate that the proposed stepping microrobot has great potential for future applications.

Cross Language Query Expansion Approach for CIMS Based on Weighted D-S Evidence Theory

With the Computer Integrated Manufacturing System and Information Technology rapid development, rapid retrieval multilingual becomes one of the hot spots in Machine Translation. The cross-language information retrieval (CLIR) provides a convenient way, enabling users to use their own familiar language to submit queries to retrieve documents in another language. Basic query expansion is one of the effective methods to improve recall of information retrieval. There are many researchers have proposed many extension methods, but most methods are simply added to the query expansion terms. If we do not distinguish the original query words and extended words, expanded query may deviate from the original semantics. So, it is very inconvenience for mechanical engineer and programmer. Based on Dempster-Shafer theory of evidence, we proposed a query expansion computing model, which considered as the main evidence of the original query terms, while the extensions as a secondary evidence of the original query terms. Which method to use semantic dictionary Han and Uygur-Chinese bilingual dictionary of synonyms forest and How to get the query word synonyms, near-synonyms and hypernym. Latent Semantic Analysis is used to obtain semantic relationships query words related words the using potentially large-scale text. The combination of these two types of evidence is in order to put forward a weighted combination of the Dempster-Shafer rule. Experimental results show that this method can effectively improve retrieval efficiency in Mechanical Engineering and Information Technology. The research results can be provided a reference for CIMS multilingual quick retrieval.
