Abstract: A first gate and a second gate are formed on a substrate with a gap between the first and second gates. The first gate has a first sidewall. The second gate has a second sidewall directly facing the first sidewall. A first sidewall spacer is disposed on the first sidewall. A second sidewall spacer is disposed on the second sidewall. A contact etch stop layer is deposited on the first and second gates and on the first and second sidewall spacers. The contact etch stop layer is subjected to a tilt-angle plasma etching process to trim a corner portion of the contact etch stop layer. An inter-layer dielectric layer is then deposited on the contact etch stop layer and into the gap.

Abstract: An electronic system includes an electronic device and a cooling device. The electronic device includes a housing, a heat source, a heat-conducting seat, and a heat-conducting block. The housing includes a space and at least one opening in communication with each other. The heat source and the heat-conducting seat are disposed in the space and contact with each. The heat-conducting seat faces the opening. The heat-conducting block is located at the opening and is connected to the housing. The cooling device includes a pressing portion and a cooling portion. The pressing portion presses the heat-conducting block, to cause the heat-conducting block to move into the space and abut against the heat-conducting seat, so that heat of the heat source is transferred to the pressing portion. The cooling portion is connected to the pressing portion, and dissipates the heat transferred to the pressing portion.

Abstract: The present invention utilizes a barrier layer in the contact hole to react with an S/D region to form a silicide layer. After forming the silicide layer, a directional deposition process is performed to form a first metal layer primarily on the barrier layer at the bottom of the contact hole, so that very little or even no first metal layer is disposed on the barrier layer at the sidewall of the contact hole. Then, the second metal layer is deposited from bottom to top in the contact hole as the deposition rate of the second metal layer on the barrier layer is slower than the deposition rate of the second metal layer on the first metal layer.
