The effects of fast neutron radiation up to flux of 1014 cm−2 (1 MeV equivalent flux) upon the turn-on and forward static characteristics of MOS-Controlled Thyristor (MCT) are described in this work, based on physics-based 1-dimension analytical calculation and 2-dimension Silvaco simulation. It is reported for the first time that dependency of on-state specific resistance (Ron) upon neutron flux...
Reliability of Superjunction (SJ) MOSFET is closely related to its manufacturing process. Experiments are carried out to investigate the electrical characteristics in high temperature of SJ MOSFET produced by deep trench filling technology. Filling holes are confirmed to be responsible for the performance deterioration in high temperature and the mechanism has been analyzed thoroughly.
Crystalline CdTe layers have been grown heteroepitaxially onto crystalline Si substrates to establish material parameters needed for advanced photovoltaic (PV) device development and related simulation. These studies suggest that additional availability of the intrinsic anion (i.e., Te) during molecular beam epitaxy deposition can improve structural and optoelectronic quality of the epilayer and the...
The goal of ranking is to learn a real-valued ranking function that induces a ranking or ordering over an instance space. A learning algorithm is stable if the algorithm satisfies the hypothesis that the output of the algorithm varies in a limited way in response to small changes made to the training set. This paper studies the `almost everywhere' stability of ranking algorithms, notions of strong...
Differential interconnect lines in multi-gigabits system in package (SiP) packaging system are studied in this paper. The performance of interconnect lines can be easily estimated with jitter and eye opening using the eye diagram that is very helpful metric. To maintain good eye-diagram with high voltage swing and low timing jitter, a signal integrity (SI) design flow of SiP is proposed based on eye-diagram...
We present a robust threshold signature scheme which is provably secure without random oracles under the computational Diffie-Hellman assumption. Our construction derives from a novel application of the recent signature scheme due to Waters. Compared with Wang et al.'s threshold signature scheme without random oracles, the signing procedure of our scheme is much more efficient in terms of communication...
This paper discusses a novel quasi-three-dimensional PN Junction capacitor, which has a high density of capacitance (200nF/cm2) with a relatively high working frequency (3GHz). These properties are because of its unique trench structure. To identify the performance of this kind of capacitor, some tests were carried out at both low frequency and high frequency. Moreover, a typical power supply filter...
Experiments were conducted to evaluate cuts made with the rake face of the tool and the clearance face. The technique involved cutting in the corresponding opposite directions, i.e., forward with the rake face and backward with the clearance face. Cutting of single crystal silicon with both the rake and the clearance face resulted in a smooth ductile cut, with no evidence of fracture. This cutting...
