Abstract:
A FINFET transistor structure includes a substrate, a fin structure, an insulating layer and a gate structure. The fin structure is disposed on the substrate and directly connected to the substrate. Besides, the fin structure includes a fin conductive layer and a bottle neck. The insulating layer covers the substrate and has a protruding side which is formed by partially surrounding the bottle neck of the fin structure, and a bottom side in direct contact with the substrate so that the protruding side extend to and under the fin structure. The gate structure partially surrounds the fin structure.
Abstract:
A semiconductor device and a method of fabricating the same, the semiconductor device includes a hard mask layer and a plurality of spacers. The hard mask layer is disposed on a target layer and has a first material and a second material. The spacers are disposed on the hard mask layer, wherein a first portion of the spacers is disposed on the first material, and a second portion of the spacers is disposed on the second material.
Abstract:
A semiconductor process includes the following steps. A first gate is formed on a substrate, wherein the first gate includes a stacked gate on the substrate and a cap on the stacked gate. A spacer material is formed to conformally cover the first gate and the substrate. The spacer material is etched to form a spacer on a side of the first gate and a block on the other side of the first gate corresponding to the side. A material covers the substrate, the block, the first gate and the spacer, wherein the top surface of the material is a flat surface. The block, the spacer and the material are pulled down with the same pulling selectivity so that an assisting gate is formed from the block and a selective gate is formed from the spacer.
