Abstract: A semiconductor device and a method of forming the same are provided. The semiconductor device includes a substrate, a gate structure, a dielectric structure and a contact structure. The substrate has source/drain (S/D) regions. The gate structure is on the substrate and between the S/D regions. The dielectric structure covers the gate structure. The contact structure penetrates through the dielectric structure to connect to the S/D region. A lower portion of a sidewall of the contact structure is spaced apart from the dielectric structure by an air gap therebetween, while an upper portion of the sidewall of the contact structure is in contact with the dielectric structure.

Abstract: Devices and method for forming a switch including a heater layer including a first heater pad, a second heater pad, and a heater line connecting the first heater pad and the second heater pad, a phase change material (PCM) layer positioned in a same vertical plane as the heater line, and a floating spreader layer including a first portion positioned in the same vertical plane as the heater line and the PCM layer, in which the first portion has a first width that is less than or equal to a distance between proximate sidewalls of the first heater pad and the second heater pad.

Abstract: The present application relates to a driving circuit for display panel, which drives a plurality of pixel structures of a display panel. Each of pixel structures comprises a light emitting element, which is coupled between a first voltage and a second voltage. The driving circuit comprises a power supply circuit, which is coupled to the pixel structures, provides the first voltage and the second voltage, and adjusts the first voltage or/and the second voltage for adjusting a voltage difference between the first voltage and the second voltage. That is, a current flowing through the light emitting elements of the pixel structures may be adjusted for reducing the flicker in the display panel.

Abstract: A working machine includes a base, at least one z-axis track mounted on the base, a secondary z-axis track mounted on the base, at least one z-axis saddle mounted on the z-axis track, a secondary z-axis saddle mounted on the secondary z-axis track, at least one x-axis track mounted on the z-axis saddle, at least one x-axis slide mounted on the x-axis track, at least one upright support mounted on the x-axis slide, and at least one y-axis track mounted on the upright support. Thus, the y-axis track is disposed at a vertical state so that the y-axis track is operated exactly and stably to facilitate operation of the working machine and to enhance the working precision and stability of the working machine.
