The lateral gas supply port is formed at the recessed portion and may supply gas toward gas supplied from the central gas supply port so that a flow direction of the gas supplied from the central gas supply port is bent from a direction along the focal line toward the exhaust port and an internal space of the recessed portion. | 2021-09-16 |
20210289612 | PLASMA MEASURING APPARATUS AND PLASMA MEASURING METHOD - A plasma measuring apparatus includes a chamber; a stage provided in the chamber; a plasma generation source configured to generate plasma in the chamber; a transmission window provided in the chamber and configured to transmit light; a phosphor arranged in the chamber and configured to emit light according to energy of incident electrons; a spectroscope arranged outside the chamber and configured to measure light emission from the phosphor through the transmission window; and a controller configured to measure an ion energy from measurement results by the spectroscope. | 2021-09-16 |
20210289613 | STRUCTURAL ELEMENT FIXING STRUCTURE AND FIXING ELEMENT THEREOF - A structural element fixing structure is provided. A flange of a first fixing element is connected with a side surface of a first shaft of the first fixing element. A first structure is fixed on the first fixing element. A second fixing element clamps the flange. An accommodating portion of the second fixing element is connected with a groove portion of the second fixing element. The accommodating portion has an accommodating space configured to accommodate the flange. A second shaft of the second fixing element is connected with the accommodating portion and is on a side of the accommodating portion facing away from the groove portion. A second structure is fixed on the second shaft of the second fixing element. The second fixing element separates the second structure and the first fixing element. | 2021-09-16 |
20210289614 | CIRCUIT CARRIER STRUCTURE AND MANUFACTURING METHOD THEREOF - A circuit carrier structure includes an inner circuit structure, at least one first circuit layer, and at least one heat dissipating structure. The inner circuit structure has a first surface and a second surface opposite to the first surface. The first circuit layer is disposed on the first surface of the inner circuit structure. The heat dissipating structure is disposed in the first circuit layer. The heat dissipating structure includes a first heat dissipating pattern, a second heat dissipating pattern and an interlayer metal layer. The first heat dissipating pattern is embedded in the corresponding first circuit layer. The second heat dissipating pattern is disposed on the first heat dissipating pattern. The interlayer metal layer is disposed between the first heat dissipating pattern and the second heat dissipating pattern. A manufacturing method of the circuit carrier structure is also provided. | 2021-09-16 |
