Title: Integrated power semiconductor component with protection structure
Inventor: GANTIOLER JOSEF-MATTHIAS
IPC: H01L27/02
Filed: 1995-05-25
Granted: 2000-03-21
Abstract: If power ICs are operated as high-side switches on an inductive load, then malfunctions may result when switching off the load. These are caused by voltage reversal at the drive IC, by which parasitic structures between the drive IC and control circuit of the high-side switch are switched on. There is a protection region, which is at the potentials of the control circuit, between the drive IC and the control circuit. The parasitic structures are then consequently formed only between the drive IC and the protection region.

Filed: 1995-09-06
Granted: 1996-08-01
Abstract: The invention relates to the methods or preparing 2-mercaptobenzimidazole (MBI) and its derivatives, which are produced from the reaction of carbon disulfide and o-phenylene diamine by tertiary amine (or quaternary ammonium salt and/or alkaline substance) in a gas-liquid two-phase solution. The chemical formulas of the product of MBI and its derivatives are expressed by formula (I) (see claim 1) in which R1, R2, R3 and R4 are independently selected from the group: hydrogen, nitro, halogen and C1-C12 alkyl or alkoxyl. The reaction was carried out in a gas-liquid two-phase solution, in which o-phenylene diamine shown by formula (II), catalyst and/or alkaline compound were dissolved in organic solvent (A). Carbon disulfide, which was dissolved in organic solvent (B), was heated to a vapor form and introduced to the reactor for reaction with o-phenylene diamine. (see claim II). Those organic solvents (A) are: MeOH, EtOH, MeCN, DMF, DMSO, THF, PC (propylene carbonate), FM (formamide), MFM(N-methyl formamide) and PEG (polyethylene glycol) etc.. The boiling points of the organic solvents (B) is smaller than that of organic solvents (A). The alkaline compounds are selected from potassium hydroxide, sodium hydroxide, ammonia, sodium hydrocarbonate and sodium carbonate etc.. The catalysts are selected from tertiary amine, quaternary ammounium salts and/or alkaline substances. The characteristics of this process are: (a) the enhancement of the rate of reaction of o-phenylene diamine and carbon disulfide and the increase of the yield of MBI product by adding a small amount of catalyst, (b) carrying out the reaction at a higher temperature from which the gas-liquid two-phase reaction took place, (c) setting the reaction temperature between the boiling point of organic solvent (A) and organic solvent (B). The residue of carbon disulfide was vaporized accompanying with organic solvent (B) and was recovered through a condenser, (d) carrying out the reaction in a closed container from which the pollution problem was minimized, and (e) obtaining high yield of the MBI product (or its derivatives) by selecting the appropriate catalysts. No byproducts were obtained.

Abstract: A low-voltage latch adapted for differential mode with a supply voltage of 2.5 V and a voltage swing of 200 mV to 300 mV is described. Two inverters are used, each having a non-inverting and an inverting input terminal and a non-inverted and an inverted output terminal. The non-inverted output terminals are connected to the input of an OR structure, and the inverted output terminals are connected to the input of another OR structure. The input terminals of one inverter form the input terminals of the latch. The input terminals of the other inverter are connected to the output terminals of the other inverter of the OR structures and form the output of the latch. The supply voltages of the inverters are varied, so that at any given time, only one inverter has an appropriate supply voltage. This inverter then controls the output of the latch. In this way, a latch function is achieved.
