In order to find the optimal condition of automated optical inspection used for inspecting mass-produced goods, a ray tracing-based simulator was developed. By using the simulator, the illuminating characteristics of an illuminator specially designed for an automated optical inspection equipment could be analyzed, and also the inspection performance could be evaluated with the simulated images.

We do not use dedicated Bosch process equipment of high cost, it is uses Bosch process that fit existent ICP(Inductively Coupled Plasma) equipment. Bosch process which is method of deep silicon etching is connected repeatedly in using SF? Plasma for etching process and using C₄F? Plasma the deposition process. However, between etching bottom layer and side wall not verticality and curved layer is formed. It is used about this curved layer phenomenon. because of considering gas fraction, temperature, substrate voltage, process time etc. It is used about this curved layer phenomenon and suggested optimum process condition. Standard process for study of process gas used SF? and Ar, and source power 600W, substrate voltage used -200V. Deposition process used C₄F? gas, and source power 600W, substrate voltage did not used. Process substrate temperature makes via 0℃ and progressed study. Through these processing condition, we manufactured mold for NIL(Nano Imprint Lithography) process.

Stroke is one of the most common causes of death; in particular, cardiac source of embolism may be responsible for 15-20% of ischemic strokes. Here we report a case of left atrial thrombus diagnosed by transesophageal echocardiography (TEE) immediately after induction of general anesthesia in a patient with infarction of the middle cerebral artery. In this case, an emergent craniectomy was cancelled and medical treatment was performed. This case report shows that TEE taken in the operating room may play an important role in the change of treatment plan in a patient displaying acute mental change.

Although both the topological information and the propagating characteristics of an optical waveguide device can simultaneously be measured with a Near-field Scanning Optical Microscope (NSOM), the structural distinctiveness of the device makes the height control of NSOM difficult. In order to resolve this difficulty, the hybrid method of controlling the gap between the NSOM probe and the device surface is newly proposed, this being based on the combination of a digital and an analog control method. It is shown that the proposed method is very efficient and stable in measuring a waveguide device with abrupt step coverage.
Re-Configurable tow-toss OADM Module Using 2×2 Port Optical Device
Kim, Myoung-Jin,Lee, Seung-Gol Optical Society of Korea 2003 Current Optics and Photonics Vol.7 No.1
We describe the optimal design and the fabrication of a 2$\times$2 port optical device based on the thin film filter (TFF), and also propose a 4-channel OADM module using these devices. The optical performance of the proposed OADM module is evaluated theoretically and experimentally, and is compared to that of typical OADM modules using 1$\times$2 port optical devices for 4, 8, 16 and 32 drop channels in optical transmission systems. Since the 2$\times$2 port optical device accomplishes the function of wavelength multiplexing and demultiplexing simultaneously in the proposed OADM module, the insertion loss of through channels can be improved by 1.2 dB compare to that of typical OADM modules using 1$\times$2 port optical devices. In addition, both the size and the price of the module can be reduced to 40~50%.
