Abstract: A semiconductor device which reduces the turn-off time and the accompanying switching loss in a switching semiconductor device in which conductivity modulation is used to provide a low ON-state voltage. The conductivity modulation is provided by injection of minority carriers. A minority carrier injection-control structure is provided in part of a semiconductor device to change the polarity of a voltage applied to a gate electrode to start or stop the injection of minority carriers. During the ON-state, minority carriers are injected to obtain a low ON-state voltage, while during the OFF-state, the injection of minority carriers are stopped and a channel for majority carriers is formed to eliminate the accumulation of excess carriers and to accelerate discharge, thereby reducing the turn-off time and thus the switching loss.

Abstract: This invention discloses a specific superjunction MOSFET structure and its fabrication process. Such structure includes: a drain, a substrate, an EPI, a source, a side-wall isolation structure, a gate, a gate isolation layer and source. There is an isolation layer inside the active area underneath the source. Along the side-wall of this isolation layer, a buffer layer with same doping type as body can be introduced & source can be extended down too to form field plate. Such buffer layer & field plate can make the EPI doping much higher than convention device which results in lower Rdson, better performance, shorter gate so that to reduce both gate charge Qg and gate-to-drain charge Qgd. The process to make such structure is simpler and more cost effective.

Abstract: A high-speed PWM control apparatus with adaptive voltage position and a driving signal generating method thereof is provided. The present invention automatically detects a change in the loading and adjusts the voltage position instantaneously for stabilizing the voltage and reducing the loading output power consumption. The present invention does not require a clock signal to generate a driving signal and does not require an error amplifier to control the modulation. Therefore, the present invention has a fast transient response that responds to the change of the loading instantaneously and has a stabilizing effect. When the apparatus is on a continuous conduction mode (CCM), the switching frequency of the controller is still fixed even though the input voltage Vin and the output voltage Vout are changed. The electrical-magnetic noise disturbance is improved.
