Abstract: A magnetic multi-pole propulsion array system is applied to at least one external cathode and includes a plurality of magnetic multi-pole thrusters connected adjacent to each other. Each magnetic multi-pole thruster includes a propellant provider, a discharge chamber, an anode and a plurality of magnetic components. The propellant provider outputs propellant. The discharge chamber is connected with the propellant provider to accommodate the propellant. The anode is disposed inside the discharge chamber to generate an electric field. The plurality of magnetic components is respectively disposed on several sides of the discharge chamber. One of the several sides of the discharge chamber of the magnetic multi-pole thruster is applied for one side of a discharge chamber of another magnetic multi-pole thruster.

Abstract: A chip package structure is provided. The chip package structure includes a chip. The chip package structure includes a conductive ring-like structure over and electrically insulated from the chip. The conductive ring-like structure surrounds a central region of the chip. The chip package structure includes a first solder structure over the conductive ring-like structure. The first solder structure and the conductive ring-like structure are made of different materials.

Abstract: A chuck vacuum line of a semiconductor processing tool includes a first portion that penetrates a sidewall of a main pumping line of the semiconductor processing tool. The chuck vacuum line includes a second portion that is substantially parallel to the sidewall of the main pumping line and to a direction of flow in the main pumping line. A size of the second portion increases between an inlet end of the second portion and an outlet end of the second portion along the direction of flow in the main pumping line.

Abstract: A leak check is performed on a semiconductor wafer processing tool that includes a process chamber and process gas lines, and a semiconductor wafer is processed using the semiconductor wafer processing tool if the leak check passes. Each gas line includes a mass flow controller (MFC) and normally closed valves including an upstream and downstream valves upstream and downstream of the MFC. Leak checking includes: leak checking up to the downstream valves of the gas lines with the upstream valves closed and the downstream valves of the gas lines closed; and leak checking up to the upstream valve of each the process gas line with the upstream valves of the of the process gas lines closed and with the downstream valve of the of the process gas line being leak checked open and the downstream valve of every other process gas line closed.

Abstract: A universal modem platform has different modems integrated therein for matching the protocols of telephone and data communications. The circuit structure of the universal modem platform primarily comprises a mother board and a plurality of baby boards. The mother board has a processing unit, a bit-stream/PCM converter, a cross switch, and high level data link controls. The baby board slot connectors connect the mother board with the baby boards through the cross switch, the bit-stream/PCM converter, and the high level data link controls.
