A method of manufacturing an electronic device includes forming a shallow trench isolation (STI) structure on or in a semiconductor surface layer and forming a mask on the semiconductor surface layer, where the mask exposes a surface of a dielectric material of the STI structure and a prospective local oxidation of silicon (LOCOS) portion of a surface of the semiconductor surface layer. The method also includes performing an oxidation process using the mask to oxidize silicon in an indent in the dielectric material of the STI structure and to grow an oxide material on the exposed LOCOS portion of the surface of the semiconductor surface layer.

Shallow trench isolation processing with local oxidation of silicon

The present disclosure introduces, among other things, an electronic device, e.g. an integrated circuit (IC). The IC includes a semiconductor substrate comprising a first doped layer of a first conductivity type. A second doped layer of the first conductivity type is located within the first doped layer. The second doped layer has first and second layer portions with a greater dopant concentration than the first doped layer, with the first layer portion being spaced apart from the second layer portion laterally with respect to a surface of the substrate. The IC further includes a lightly doped portion of the first doped layer, the lightly doped portion being located between the first and second layer portions. A dielectric isolation structure is located between the first and second layer portions, and directly contacts the lightly doped portion.

A thermal therapy device can be operated for both cold and hot water circulation by using a self-priming pump and four solenoid valves with the open/closed states selectively controlled by an MCU to pump chilled water or cold water from two different water containers to sequentially circulate through two different water paths to a water bladder for cold therapy treatment or hot therapy treatment. During the hot therapy treatment, a water heater is used to heat the cold water until a configured temperature is reached. A pneumatic pump is also employed to carry out an air pressure control mode to pump air into an air bladder securely attached on the water bladder to put pressure on the water bladder for a pressurized treatment. Water retained in the water bladder can also be evacuated and returned to the two different water containers to avoid moss generation and stinky odor.

A portable cooling device has a vacuum bottle, a pump, an outflow pipe, a thermal exchanger and a return pipe. The vacuum bottle holds a coolant and has an outer casing and a vacuum flask. The outer casing has a chamber. The vacuum flask is mounted in the chamber. The pump is mounted on the vacuum bottle to pump the coolant out of the vacuum bottle. The outflow pipe connects to the pump. The thermal exchanger connects to the outflow pipe, is filled by the coolant and is placed adjacent to a person to lower his body temperature. The return pipe connects between the thermal exchanger and the vacuum bottle to form a flow circle. Consequently, the portable cooling device efficiently cools the body temperature. Moreover, having the vacuum bottle to hold and insulate the coolant elongates effective cooling time of the cooling device.

A power generator includes a supporting frame, a generator supported by the supporting frame, and an engine mechanism including an engine driving the generator and a recoil starter for starting the engine via starter cable. The power generator further includes a hand-free starter arrangement which includes a foot pedal movably supported by the supporting frame and a transmission unit coupling a pulling end of the starter cable with the foot pedal to transmit the downward stepping force of the foot pedal to a pulling force of the starter cable. A downward displacement of the foot pedal is corresponding to an operation length of the starter cable to start the engine such that when the foot pedal is depressed, the starter cable is pulled with the operation length to start the engine in a hand-free manner.
