The study of vertical channel with high field effect mobility by Ni induced lateral crystallization, which can form larger grains on channel regions and reduce grain boundary defects. We detect the method of Ni induced lateral crystallization through high field effective mobility, but that accumulates too much Ni on floating N+ region and causes defects and metal contamination. As Ni is used to form silicde and then proceed to low temperature annealing, we can observe the floating region that has no Ni acumination regions or contaminations. This aids us in obtaining good electronic performance of this device, not only the remote field effective mobility but also the vast improvement of sub-threshold swing and on/off currents.

接著，是延续垂直通道的研究，希望能有效的提升电子迁移率，因此以镍金属诱导横向结晶的方式使通道形成较大的结晶，减少矽晶粒之间的缺陷，而在初步的研究，发现以镍金属直接诱导横向结晶的方式，经由低温长时间回火之后，由於镍金属扩散的关系，完成诱导结晶之后，有过多的镍金属聚集在顶部参杂的中间区域，而造成过多的缺陷累积，虽然电子迁移率有效的提升，但整体的电性并不如预期，因此提出先形成镍金属矽化物后，将未反应的镍金属或金属氧化物去除之后，再进行镍金属矽化物诱导横向结晶处理，经由结果观察得知在顶部掺杂区域部分没有明显的镍金属累积或污染，并且得到很好的整体电性，除了电子迁移率有效提升之外，次临界特性以及导通电流都能有效改善。
