  • Publication number: 20200013590
    Abstract: Embodiments are described herein to reduce formation of undesired particles during plasma processing for microelectronic workpieces by depositing a layer (e.g., think film) on the surface of a chuck, such as an electrostatic chuck (ESC), prior to plasma processing such as a plasma etch process (e.g., a reactive ion etch (RIE) process) and/or a plasma deposition process. This layer works as a lubricant or protective coating to reduce or minimize physical contact between the microelectronic workpiece (e.g., semiconductor wafer) and the chuck. This reduction in physical contact reduces scratching of the backside of the microelectronic workpiece and reduces related formation of undesired particles that can be transported to the front side of the microelectronic workpiece and cause defects and reduce yields. As such, the disclosed embodiments improve particle (PA) performance parameters for plasma etch and/or deposition processes.

  • Publication number: 20200006100
    Abstract: This disclosure relates to a high volume manufacturing system for processing and measuring workpieces in a semiconductor processing sequence without leaving the system's controlled environment (e.g., sub-atmospheric pressure). The systems process chambers are connected to each other via transfer chambers used to move the workpieces, in the controlled environment, between the process chambers. Further, the pass-through chambers may be disposed between the transfer chambers or between the transfer chamber and the process chamber. The pass-through chambers may include a measurement region to measure workpiece attributes when the workpiece is moved through or placed in the pass-through chamber. The transfer chambers may also have separate measurement regions within their internal space to measure other attributes of the workpiece.

  • Patent number: 10440857
    Abstract: The invention provides a detection system and method of signal transmission delay for fan chip. The detection system comprises a circuit board, a fan chip and a control unit. The control unit generates a first pulse signal having a specific pulse pattern, and send the first pulse signal to the fan chip. When the fan chip is operating in a detection mode of signal transmission delay according to the first pulse signal, the fan chip copies the specific pulse pattern of the first pulse signal to generate a second pulse signal having the specific pulse pattern, and send the second pulse signal to the control unit. The control unit calculates a time difference between a time that sends the first pulse signal and a time that receives the second pulse signal, so as to obtain a delay time of signal transmission between the control unit and the fan chip.
