The disclosure relates to a photovoltaic solar array which is provided with a matrix having spherical photovoltaic diode particles embedded therein in an ordered array, the P-type region of each particle extending to one matrix surface and the N-type region of each particle extending to an opposed matrix surface. Backside metallization is disposed on the matrix backside surface to interconnect the particles extending thereto and frontside conductors are provided on the opposing matrix surface to interconnect the particles extending thereto. The matrix includes two portions, the first portion being a layer extending to the frontside formed of a clear glass. The second portion of the matrix is, in effect, two layers, one disposed at the P-N junctions of the particles being a lead base glass for junction passivation, this layer being overcoated with a reflective layer to provide additional reflectivity of light entering the matrix onto the particles. This increases the amount of light impinging on the particles. The frontside of the matrix includes a light transparent conductive material with electrically conductive whiskers embedded therein for improved conductivity.

A method and apparatus for providing a meshed power and signal bus system on an array type integrated circuit that minimizes the size of the circuit. In a departure from the art, through-holes for the mesh system are placed in the cell array, as well as the peripheral circuits. The power and signal buses of the mesh system run in both vertical and horizontal directions across the array such that all the vertical buses lie in one metal layer, and all the horizontal buses lie in another metal layer. The buses of one layer are connected to the appropriate bus(es) of the other layer using through-holes located in the array. Once connected, the buses extend to the appropriate sense amplifier drivers. The method and apparatus are facilitated by an improved subdecoder circuit implementing a hierarchical word line structure.

The present invention discloses a novel integrated circuit capacitor and a method of forming such a capacitor. The capacitor formation begins with a base electrode 18 adjacent an insulating region 26. This base electrode 18 can comprise either polysilicon or a metal. A layer 28 of a first material, such as a siliciding metal, is formed over the base electrode 18 as well as the adjacent insulating region. A self-aligned capacitor electrode 12 can then be formed by reacting the first material 28 with the base electrode 18 and removing unreacted portions of the first material 28 from the insulating region 26. The capacitor is then completed by forming a dielectric layer 16 over the self-aligned capacitor electrode 12 and a second capacitor electrode 14 over the dielectric layer 16.

A method of reducing gated diode leakage in trench capacitor type field plate isolated dynamic random access memory devices is disclosed. The storage node of the capacitor is formed by placing a storage node material, such as implanted arsenic, into the trench walls of the device at a first tilt and a second tilt. The angle of the second tilt is preferably larger, higher, than the angle of the first tilt. This higher angle provides the storage node with a larger concentration of doping around the upper portion the trench walls. This larger concentration of doping reduces the charge leaking from the upper portion of the storage node into the substrate of semiconductor material. A trench type storage capacitor for a dynamic random access memory device is also disclosed.

A system and method is provided for forming semiconductor tear-drop shaped bodies having minimal grain boundaries. Semiconductor material is melted in a capillary tube at the top of a tower, and forced under gas pressure through a nozzle. Separate semiconductor bodies are formed. They are passed through a free fall path over which a predetermined temperature gradient controls solidification of the bodies. The resultant bodies are tear-drop semiconductor bodies of near uniform size with minimal grain boundaries.

An embodiment of the instant invention is a method of providing a connection between a first conductor and a second conductor wherein the first conductor is situated under the second conductor and separated by a first insulating layer, the method comprising the steps of: forming an opening in the first insulating layer (layer 124 or 128 of FIGS. 1-4), the opening having a top, a bottom and sidewalls and is situated between the first conductor and the second conductor; forming a second insulating layer (layer 134, 138, and 142 of FIGS. 3 and 4) exclusively on the sidewalls of the opening thereby leaving a smaller opening in the first insulating layer; forming a conductive material (material 140 of FIGS. 3 and 4) in the smaller opening; and wherein the first insulating layer is comprised of a low-k material and the second insulating layer is comprised of an insulator which has electrical leakage properties which are less than the electrical leakage properties of the first insulating layer.
