摘要:
A circuit for charging a capacitor block including series-connected capacitive elements has an input node for receiving an input, an output node coupled to the capacitor block, a third capacitive element connectable to the input node and the output node, and first and second switching circuitries coupled to the third capacitive element. A voltage sensor determines a relationship between first voltage at the first capacitive element and second voltage at the second capacitive element to separately control switching of the first and second switching circuitries in accordance with the relationship between the voltages.

The present invention belongs to the technical field of semiconductor materials and specifically relates to a method for cleaning & passivizing gallium arsenide (GaAs) surface autologous oxide and depositing an Al2O3 dielectric. This method includes: use a new-type of sulfur passivant to react with the autologous oxide on the GaAs surface to clean it and generate a passive sulfide film to separate the GaAs from the outside environment, thus preventing the GaAs from oxidizing again; further cleaning the residuals such as autologous oxides and sulfides on the GaAs surface through the pretreatment reaction of the reaction source trimethyl aluminum (TMA) of the Al2O3 ALD with the GaAs surface, and then deposit high-quality Al2O3 dielectric through ALD as the gate dielectric which fully separates the GaAs from the outside environment. The present invention features a simple process and good effects, and can provide preconditions for manufacturing the GaAs devices.

The invention provides a method for producing titanium tetrachloride by using a low grade titanium material, and belongs to the chemical field. The technical problem to be solved is to provide a method for producing titanium tetrachloride by using a low grade titanium material capable of continuous industrialized production. The method is characterized in that the low grade titanium material containing a certain proportion of titanium carbide is caused to directly react with chlorine at 600-700° to produce the titanium tetrachloride. Long-time continuous and stable operation can be realized by using the process parameters of the method, and chlorination rate of the titanium carbide in the titanium material reaches above 90%, so that the titanium material can be better used for producing the titanium tetrachloride.
