    • In the fabrication of electrodes for transistors in the BiCMOS integrated circuit, vertical windows etched in a relatively thick TEOS (or other suitable dielectric) layer, located on a relatively thin polysilicon layer, in turn located on relatively tin oxide layer areas and on relatively thick oxide layer areas, are used to define areas where polysilicon electrode material is to remain. Polysilicon is deposited in the windows in the relatively thick insulating layer, to form the basis for the desired electrode in each window. The relatively thin polysilicon layer (or, alternatively an .alpha.-amorphous silicon layer) is thereafter used as an etch stop during the subsequent removal of the relatively thick dielectric layer. Thereafter both MOS and bipolar transistors can be fabricated using the windows to define the extents of the gate regions of the MOS transistors and the extents of the emitter regions of the bipolar transistors. In addition, both the source and drain electrodes of the MOS transistors and the base electrodes of the bipolar transistors can then be simultaneously formed in a self-aligned manner without the need for etching into the underlying semiconductor substrate in which the integrated circuit is being formed.
    • 在BiCMOS集成电路中用于晶体管的电极的制造中,在位于相对较薄的多晶硅层上的相对较厚的TEOS(或其它合适的电介质)层中蚀刻的垂直窗口依次位于相对锡氧化物层区域上并且相对较厚 氧化物层区域用于限定保留多晶硅电极材料的区域。 多晶硅沉积在相对厚的绝缘层中的窗口中,以形成每个窗口中所需电极的基础。 此后,在相对较厚的电介质层的去除期间,相对薄的多晶硅层(或者可选地,α-非晶硅层)被用作蚀刻停止层。 此后,可以使用窗口来制造MOS和双极晶体管,以限定MOS晶体管的栅极区域的范围和双极晶体管的发射极区域的范围。 此外,MOS晶体管的源电极和漏电极以及双极晶体管的基极可以以自对准的方式同时形成,而不需要蚀刻到其中形成集成电路的下面的半导体衬底 。

    • An apparatus for an ion trap includes a semiconductor or dielectric wafer with front and back surfaces, a sequence of alternating conductive and dielectric layers formed over said front surface, and a bottom conductive layer. The sequence includes top and middle conductive layers, wherein the middle conductive layer is closer to the wafer than the top conductive layer. The middle conductive layer includes a substantially right cylindrical cavity that crosses a width of the middle conductive layer. The top and bottom conductive layers cap respective first and second ends of the cavity. The top conductive layer includes a hole that forms a first access port to the cavity. The wafer includes via through the width of the wafer. The via provides another access to the cavity via the back surface of the wafer. The wafer is substantially thicker than the sequence of layers.

    • A process for fabricating a silicon-on-insulator integrated circuit in conjunction with a process for shallow trench isolation is disclosed. The shallow trench isolation is performed to define active regions in the silicon substrate. The active regions are electrically isolated from each other by regions of silicon dioxide formed in the substrate by the shallow trench isolation process. The height of the silicon dioxide regions above the substrate surface defines the combined thickness of the islands of silicon dioxide and the silicon formed over the islands of silicon dioxide. A mask is then formed on the silicon substrate with the regions of silicon dioxide formed therein. The mask defines the regions on the silicon substrate surface on which the islands of silicon dioxide are to be formed. The silicon dioxide islands are formed with the mask in place, and the mask is subsequently removed. Single crystal silicon is formed epitaxially on the structure. This is followed by the deposition of amorphous silicon and recrystallization to form a structure that has islands of insulating silicon dioxide formed in the silicon substrate and below the substrate surface.
