摘要:
A bi-MOS circuit is fabricated on first active regions assigned to the bipolar transistor and on second active regions assigned to the field effect transistors, and the field effect transistors are fabricated after said bipolar transistor, because a high-temperature heat treatment for an emitter diffusion destroys the impurity profiles of the source/drain regions of the field effect transistors, wherein a part of the field oxide layer between the second active regions is covered with an etching stopper layer before deposition of a thick silicon oxide layer in order to widely space the emitter region from the emitter electrode, even though the thick silicon oxide layer is removed from the field oxide layer between the second active regions for fabricating the field effect transistors, the etching stopper layer prevents the field oxide layer from the etchant, and the field oxide layer between the second active regions maintains the original thickness, thereby never allowing a parasitic MOS transistor to turn on.
摘要:
There is provided a burner structure used for a portable gas cooking stove, including a mixing tube with an open end from which a mixture gas of a combustible gas and air is discharged, a burner head with a predetermined volume, an open bottom surface, and a top surface with at least one opening, an inner cup having a size that enables the inner cup to be housed in the burner head, and an open bottom surface, and a bottom plate with a through-hole through which the mixing tube can be inserted, covering the open bottom surface of the burner head, wherein the inner cup is installed inside the burner head in such a manner that an inner surface of the inner cup faces the mixing tube, and the mixing tube is installed on the bottom plate so that the open end is positioned higher than a bottom surface of the inner cup. The burner structure decreases the flow rate of the gas mixture before the gas is discharged out of the burner structure, and when the gas is discharged out of the burner structure, the flow rate of the gas is substantially the same as the normal combustion rate. Therefore, the burner structure for a portable gas cooking stove can effectively prevent the occurrence of lift that may take place if the flow of the gas mixture is excessive, so all the gas mixture can be burned completely.
