    Abstract:  配線の断線やショートを生じずに、低コスト化と素子間の電気的絶縁を図ることができる半導体装置を提供する。  半導体素子、並びに、半導体素子の直下に存在する低抵抗層を、接地された貫通ビアで囲むため、半導体素子は電気的に遮蔽される。そのため、隣接素子間との電気的絶縁が可能になる。従って、再成長技術や溝を形成する必要が無いため、配線の断線やショートを生じずに、低コストで電気的絶縁が可能になる。

    Abstract translation: 提供了一种低成本的半导体器件,其中元件彼此电绝缘,而不会发生布线的断开和短路。 由于半导体元件正下方存在的半导体元件和低电阻层被接地的通孔包围,所以半导体元件被电屏蔽。 因此,半导体元件可以与相邻元件电绝缘。 由于不需要再生技术和形成沟槽,所以以低成本提供电绝缘,而不会产生断线和布线短路。

    Abstract: A method of providing a region of doped semiconductor (40) which is buried below the surface of a semiconductor substrate (10) without the requirement of epitaxially deposited layers is provided. The method includes the steps of forming first and second trench portions (26,28) in a semiconductor substrate and then introducing dopant (100) into the trench portions and diffusing the dopant into the semiconductor substrate such that a region of doped semiconductor (40) is formed extending from the first trench portion to the second trench portion. A diffusion barrier, for example formed of two barrier trenches (16,18), is provided in the substrate adjacent the doping trenches to inhibit lateral diffusion of dopant from the doping trenches so as to maintain an undoped region (30) above the region of doped semiconductor. Advantageously, the electrical properties of the buried layer can be adjusted by varying the depths and size/spacing of the doping trenches and diffusion barrier(s), and the doping and diffusion parameters. The doping trenches can later be filled with polysilicon to provide electrical contact to the buried doped region.

    Abstract translation: 提供一种埋置在半导体衬底(10)的表面下方的掺杂半导体(40)的区域的方法,而不需要外延沉积层。 该方法包括以下步骤:在半导体衬底中形成第一和第二沟槽部分(26,28),然后将掺杂剂(100)引入沟槽部分并将掺杂剂扩散到半导体衬底中,使得掺杂半导体(40)的区域 形成为从第一沟槽部分延伸到第二沟槽部分。 例如由两个势垒沟槽(16,18)形成的扩散阻挡层设置在邻近掺杂沟槽的衬底中,以抑制掺杂剂从掺杂沟槽的横向扩散,以便将未掺杂的区域(30)保持在 掺杂半导体。 有利地,可以通过改变掺杂沟槽和扩散势垒的深度和尺寸/间距以及掺杂和扩散参数来调节掩埋层的电性能。 稍后可以用多晶硅填充掺杂沟槽以提供与掩埋掺杂区域的电接触。
