Taking the case of AVS standards as research sample,the paper explores the mechanism of founding homegrown standards based on the allying behavior.

In recent years,the negative effects of the shortage of homegrown standards on economic development and industrial security have become more and more obvious in China,so an effective approach of establishing homegrown standards is needed urgently.

Automatic alignment between a laser diode and a single-mode fiber;

An automatic alignment system is presented for assembly between the nozzle and the solid propellant motor to resolve the problem of the manual work.

A new automatic alignment method of fuzzy alignment and accurate alignment and theory of secondary camera calibration are proposed.

Design of a double poly-silicon self-aligned PNP transistor for C-bipolar technology;

Aiming at improving accuracy of photoetching technology in conventional double-mesa process,this article introduced buried-metal layers and developed silicon based buried-metal self-aligned process in order to increase the mesa area utilization efficiency.

The groove-gate MOSFETs with 140nm channel length fabricated with a self-aligned process are tested,and the results effectively show the superiority of the groove-.
