Recently, as the industrial structure and working environment change due to the structural deepening of low birthrates and aging and the rapid development of information technology in our society, discussions on the reemployment of retirees can be very important. Therefore, we sought to carry out empirical testing on the path that leads to the re-employment intentions from the positive psychological capital of the retiree in this study. It was shown in the research result that as positive psychological capital, self-efficacy and hope have a positive impact on career planning and self-efficacy and optimism have a positive impact on career commitment relationships. In addition, career planning was shown to have a positive impact on career commitment and re-employment intentions. And in the relationship between career planning and career commitment and re-employment intentions, social support was shown to have a moderating effect. Through this study, we intend to provide theoretical support and foundation for the proactive and systematic career development and the resulting career success of the retiree.

A wafer rolling etching system for the silicon bulk micromachining has been designed and fabricated. The silicon diaphragms were anisotropically etched in a 24.5 weight percent KOH solution. Compared to the conventional KOH etching systems, pyramidal hillocks, and wave-shaped structures on the etched surfaces were greatly reduced by using this system. After etching for time of 438 minutes, the average etched depth and the etch-rate were measured to be 537μm and 1.22μm/min, respectively. The average etching uniformity of etching depth was 0.87% in 5-inch wafer. Our results showed that the wafer rolling method enhanced etch uniformity and etch rate.

In this paper, we studied the anodic bonding of 5-inch silicon and #7740 Pyrex glass wafers with a thickness of 3mm by using the EV501 bonder and the Karl Suss SB6 bonder. The test conditions for anodic bonding of the EV501 bonder system with a full field electrode were temperature of 400 ℃ and voltage of 800V in a chamber pressure of 1X10^(3)mbar. The SB6 bonder with a star shaped electrode was tested at the temperature and voltage of 450 ℃ and 1300V in the atmosphere, respectively. As the results of test, we obtained the void free samples regardless of shape of substrates such as etched wafers with cavities and drilled glasses with holes.

An integrated silicon pressure sensor has been designed, fabricated and tested. The signal conditioning circuits were designed to include calibration and temperature compensation of output voltage through trimming of diffusion and ion-implanted resistors. Before trimming of resistors, the compensation parameters such as pressure sensitivity, temperature coefficient of pressure sensitivity, temperature coefficient of piezoresistors and pressure sensitivity of piezoresistors were measured. Then offset voltage, span, and temperature coefficients of offset voltage and span were calibrated by trimming of resistors. The measured output voltage met our design specification and simulation value above room temperature. But, the measured output voltage at -30°C deviated from our design specification and simulation value because the offset voltages were found to vary randomly as a function of temperature.
