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: Integrated circuit packages and methods of forming the same are discussed. In an embodiment, a device includes: a package substrate; a semiconductor device attached to the package substrate; an underfill between the semiconductor device and the package substrate; and a package stiffener attached to the package substrate, the package stiffener includes: a main body extending around the semiconductor device and the underfill in a top-down view, the main body having a first coefficient of thermal expansion; and pillars in the main body, each of the pillars extending from a top surface of the main body to a bottom surface of the main body, each of the pillars physically contacting the main body, the pillars having a second coefficient of thermal expansion, the second coefficient of thermal expansion being less than the first coefficient of thermal expansion.

Abstract: Some implementations described herein a provide a multi-die package and methods of formation. The multi-die package includes a dynamic random access memory integrated circuit die over a system-on-chip integrated circuit die, and a heat transfer component between the system-on-chip integrated circuit die and the dynamic random access memory integrated circuit die. The heat transfer component, which may correspond to a dome-shaped structure, may be on a surface of the system-on-chip integrated circuit die and enveloped by an underfill material between the system-on-chip integrated circuit die and the dynamic random access memory integrated circuit die. The heat transfer component, in combination with the underfill material, may be a portion of a thermal circuit having one or more thermal conductivity properties to quickly spread and transfer heat within the multi-die package so that a temperature of the system-on-chip integrated circuit die satisfies a threshold.

Abstract: Embodiments of a method for selecting an antenna set and a wireless communication device utilizing the same are described. The wireless communication device includes a set of external antenna ports, a set of internal antennas, a communication circuit and a controller. The set of external antenna ports receives a set of first RF signals from a set of external antennas. The set of internal antennas receives a set of second RF signals. The communication circuit, coupled to the set of external antenna ports and the set of internal antennas, determines a first signal quality according to the set of first RF signals, determines a second signal quality according to the set of second RF signals, determines which of the first or second signal quality is higher, and switches to the set of antennas which correspond to the higher signal quality.
