Since minority carriers can diffuse over large distances in the common substrate and disturb circuits in their normal operation, a quantitative approach is necessary to address this parasitic effect early during design. An equivalent circuit based on the chip's design is extracted and the coupling effect between the perturbing devices and the susceptible nodes is represented by Verilog-AMS models. An automated layout extraction identifies the perturbators and the sensitive devices and determines the parameters for the models. The equations of the models are derived from calibrated TCAD simulations based on measurements of a dedicated test chip. Finally, the entire simulation flow is evaluated and the simulation results are compared to measurements of the chip.","PeriodicalId":202561,"journal":{"name":"2017 29th International Symposium on Power Semiconductor Devices and IC's (ISPSD)","volume":"42 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2017-05-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116295720","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The output transistor was designed by alternatively arranging high- and low-side transistors to enhance the thermal diffusion from self-heated transistors. A 42% increase in the failure energy of the conventional transistor was obtained at 300-μs short-circuit duration, and a further 10–15% improvement was obtained by introducing a Cu redistribution layer (Cu-RDL) of power metal. A 3D-thermal simulation demonstrated that the peak junction temperature was reduced by around 100°C in the hybrid output transistor during clamp inductive switching. The energy capability of the hybrid output transistor also improved from 18 to 31 mJ in the solenoid driver circuit.","PeriodicalId":202561,"journal":{"name":"2017 29th International Symposium on Power Semiconductor Devices and IC's (ISPSD)","volume":"39 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2017-05-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126480901","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

At the turn-off phase, a hump appears in the drain current. Both experiment and simulation indicated that the amplitude of the current hump drastically depends on the charge imbalance (CIB). On the other hand, at the turn-on phase, calculation showed that the dependence of di/dt on CIB is opposite in the cases of planar or trench gate structure. These changes of switching waveform are caused by the electrostatic potential distribution around the gate structure.

High-speed power MOSFET with low reverse transfer capacitance using a trench/planar gate architecture 采用沟槽/平面栅极结构，具有低反向传递电容的高速功率MOSFET

The device is comprehensively studied with numerical simulations, and comparisons are made with the conventional MOSFET (C-MOS) and the split-gate MOSFET (SG-MOS). Compared to the C-MOS, the removal of the MOS-structure above the JFET region results in a dramatic reduction of the reverse transfer capacitance (Crss) in the SG-MOS and TP-MOS. The top p-base in the TP-MOS expedites the depletion in the JFET region, which helps further reduce the Crss and alleviates the electric field crowding. The additional trench channels in the TP-MOS lowers the total channel resistance, which compensates the increase of JFET resistance caused by the absence of the electron accumulation layer under the MOS-structure. Therefore, the TP-MOS achieves the best RON-Crss trade-off.","PeriodicalId":202561,"journal":{"name":"2017 29th International Symposium on Power Semiconductor Devices and IC's (ISPSD)","volume":"148 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2017-05-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127243721","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

As an application example, the developed CMOS gate driver carries the digital data through an optical isolation, in the context of wide bandgap power transistors. The receiver chip integrates all the required functions from the optical receiver to the signal processing circuit (SPC) and the logic control units. The standard AMS HV 0.18 μm CMOS technology is selected for proof of concept and prototyping. A variable frame length serial communication protocol is implemented with an integrated clock to transfer a 4 bit commutation order within 56 ns and an 8 bit configuration data within 84 ns (140 Mbps). Hence, a segmented output stage buffer can be configured by light, thus dynamically changing the gate resistor value through the isolation barrier.","PeriodicalId":202561,"journal":{"name":"2017 29th International Symposium on Power Semiconductor Devices and IC's (ISPSD)","volume":"131 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2017-05-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132385257","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
