Knife Blade

A knife blade cutting experiment was performed to study the effect of clearance between two knife blades on cutting only one layer of a multi-layer thin film. The multi-layer thin films are made up of three major layers: a 0.1mm Polyethylene terephthalate (PET) layer, a 25 ~ 50 μm elastic plastic layer, and a 0.18 mm paper layer. The clearance between two knife blades is controlled by a micro manual stage. The cutting parameters are the clearance of knife blades, the edge of knife blades, and cutting speed. The relationships between layers to be cut and clearance between knife blades are measured using specific knife blades and a constant cut speed. Using the experimental results, several criteria for cutting paper layer are critically assessed. Through assessment of the criteria, the paper layer alone is practicably removed from multi-layer thin film. This experiment successfully provided a method to cut a specific layer but other layers of multi-layer thin film at once.

In this work, the influences of plasma pre-treatment on polyethylene terephthalate (PET) substrate to the properties of ZnO thin film have been carried out. ZnO thin films were successfully grown on PET substrate by spin coating method. In order to study the effects of plasma pre-treatment, a comparison of treated and untreated condition was employed. Water contact angle measurement had been carried out for PET wettability study prior to ZnO thin film coating. Morphology study of ZnO thin film was performed by scanning probe microscope (SPM). Besides, optical study of the ZnO thin film was done by using UV-vis spectrophotometer. All the measured results show that plasma pre-treatment of PET substrate plays an important role in enhancing the wettability of PET and optical properties of the ZnO thin films. In conclusion, pre-treatment of PET surface is essential to produce higher quality ZnO thin film on this particular substrate in which would pave the way for the integration of future devices.

Extension Ratio

Tensile stress was applied to β-AgI thin film prepared on a polyethylene terephthalate film, and the ion conduction response in the direction of the tensile extension was investigated. The ionic conductivity of the β-AgI thin film decreases and the activation energy for ionic conduction increases with increasing extension ratio. This behaviour is attributed to the modulation of the crystal framework by the extension of the AgI thin film.

Flexible electronics represent an emerging area in the electronics packaging and systems integration industry with the potential for new product development and commercialization in the near future. Manufacturing electronics on flexible substrates will produce low cost devices that are rugged, light, and flexible. However, electronic systems are vulnerable to failures caused by mechanical and thermal stresses. For electronic systems on flexible substrates repeated stresses below the ultimate tensile strength or even below the yield strength will cause failures in the thin films. It is known that mechanical properties of thin films are different from those of bulk materials; so, it is difficult to extrapolate bulk material properties on thin film materials. The objective of this work is to study the behavior of thin-film metal coated flexible substrates under high cyclic bending fatigue loading. Polyethylene terephthalate (PET) and polyethylene naphthalate (PEN) are widely used substrates in the fabrication of microelectronic devices. Factors affecting the fatigue life of thin-film coated flexible substrates were studied, including thin film thickness, temperature, and humidity. A series of experiments for sputter-deposited copper on PET substrates were performed. Electrical resistance and crack growth rate were monitored during the experiments at specified time intervals. High magnification images were obtained to observe the crack initiation and propagation in the metal film. Statistical analysis based on design of experiments concepts was performed to identify the main factors and factor’s interaction that affect the life of a thin-film coated substrate. The results of the experiments showed that the crack starts in the middle of the sample and slowly grows toward the edges. Electrical resistance increases slightly during the test until the crack length covers about 90% of the total width of the sample where a dramatic increase in the resistance takes place.

Fundamental Parameter Method

The fundamental parameter method for x-ray spectrometry has been used most commonly for bulk samples, because it permits an analysis utilizing a minimum number of standards, even for samples with complicated matrices. The need for the analysis of thin film materials, which includes multi-layer films, has been increasing in recent years along with the rapid progress of high technologies. However, there have been few reports that deal with the application of fundamental parameter methods to multi-layer thin films. There may be two situations in the analysis of thin films. In routine analysis of quality control applications, they usually require precise analysis. Fortunately, it is possible to prepare well characterized standards similar to the unknowns.

Based on the single-layer thin film theory, we calculated transmittance of ITO thin film. The reflectivity arrive a maximum or a minimum according to whether the refractive index of film is greater or smaller than the refractive index of the glass substrate. we obtain the same maximum of transparence which is above 95% and the minimum value which decrease to 76.5% with the increase of refractive index.

Precision ultrasonic vibration cutting (UVC) is a promising technology in field of precision and ultra-precision machining. It is a kind of the pulsing cutting process with a constant vibration frequency and sine-wave amplitude of vibration. Its practicability has been a research focus since it came into being. In this article, an precision UVC system is built by designing this system, including the selection of precision machine and ultrasonic generator, the design of ultrasonic transducer, and then many cutting experiment are been done. Different of chips under the conditions of ultrasonic and no ultrasonic are made, and deformation coefficient of chip obtained by vibration cutting is smaller. The effect of cutting parameters on roughness is discussed in precision vibration cutting, the surface roughness decreased with the increase of the amplitude and the decrease of the cutting depth or feed rate, at the same time, there is an optimum cutting speed to receive the best surface.

β-AgI thin films with thicknesses of 0.09–8.9 µm were prepared on polyethylene terephthalate (PET) substrate. Dependence of ionic conductivity on the thickness of the β-AgI thin film was measured via impedance spectroscopy in the temperature range of 300–330 K. It has been confirmed that the ionic conductivity of the b-AgI thin film is several hundred times higher than the b-AgI bulk. The enhancement of ionic conductivity is considered to be due to the formation of a high ion-conducting region near the hetero-interface region of b-AgI and PET. Furthermore, it has been suggested that the activation energy and carrier density may change depending on the distance from the interface, and the thickness dependence of enhancement in ionic conductivity may be related to the film thickness dependence of crystal orientation and structural disorder of β-AgI thin films.
