摘要:
Semiconductor devices are described that have a through-substrate via formed therein. In one or more implementations, the semiconductor devices include a top wafer and a bottom wafer bonded together with a patterned adhesive material. The top wafer and the bottom wafer include one or more integrated circuits formed therein. The integrated circuits are connected to one or more conductive layers deployed over the surfaces of the top and bottom wafers. A via is formed through the top wafer and the patterned adhesive material so that an electrical interconnection can be formed between the integrated circuits formed in the top wafer and the integrated circuits formed in the bottom wafer. The via includes a conductive material that furnishes the electrical interconnection between the top and bottom wafers.

In one embodiment of the invention, a method for finishing or treating a silicon-containing surface is provided which includes removing contaminants and/or smoothing the surface contained on the surface by a slow etch process (e.g., about 100 Å/min) is provided which includes removing silicon-containing material to form a recess in a source/drain (S/D) area on the substrate. In another embodiment, a method for cleaning a process chamber is provided which includes exposing the interior surfaces with a chamber clean gas that contains an etchant and a silicon source. The chamber clean process limits the etching of quartz and metal surfaces within the process chamber.

The present invention has various aspects relating to the maximization of current carrying capacity of wafer level packaged chip scale solder pad mounted integrated circuits. In one aspect, the solder pad areas are maximized by using rectangular solder pads spaced as close together as reliable mounting to a circuit board will allow. In another aspect, multiple contact pads may be used for increasing the current capacity without using contact pads of different areas. In still another aspect, vias are used to directly connect one lead of high current component or components to a contact pad directly above that component, and to route a second lead of the high current component to an adjacent contact pad by way of a thick metal interconnect layer.

In a first aspect, a first method of forming an epitaxial film on a substrate is provided. The first method includes (a) providing a substrate; (b) exposing the substrate to at least a silicon source so as to form an epitaxial film on at least a portion of the substrate; and (c) exposing the substrate to HCl and Cl2 so as to etch the epitaxial film and any other films formed during step (b). Numerous other aspects are provided.

The present invention provides systems and methods of forming an epitaxial film on a substrate. After heating in a process chamber, the substrate is exposed to a silicon source and at least one of SiH2(CH3)2, SiH(CH3)3, Si(CH3)4, 1,3-disilabutane, and C2H2, at a temperature of greater than about 250 degrees Celsius and a pressure greater than about 1 Torr so as to form an epitaxial film on at least a portion of the substrate. Then, the substrate is exposed to an etchant so as to etch the epitaxial film and any other films formed during the deposition. The deposition and etching may be repeated until a film of a desired thickness is achieved. Numerous other aspects are disclosed.

In one example, a method of epitaxially forming a silicon-containing material on a substrate surface is presented which includes positioning a substrate into a process chamber. The substrate has a monocrystalline surface and at least a second surface, such as an amorphous surface and/or a polycrystalline surface. The substrate is exposed to a deposition gas to deposit an epitaxial layer on the monocrystalline surface and a polycrystalline layer on the second surface. The deposition gas preferably contains a silicon source and at least a second elemental source, such as a germanium source, a carbon source and/or combinations thereof. Thereafter, the method further provides exposing the substrate to an etchant gas to etch the polycrystalline layer and the epitaxial layer in a manner such that the polycrystalline layer is etched at a faster rate than the epitaxial layer. The method may further include a deposition cycle that includes repeating the exposure of the substrate to the deposition and etchant gases to form a silicon-containing material with a predetermined thickness.

The method further provides depositing on the first silicon-containing layer a second silicon-containing layer wherein a second germanium concentration of about 15 at % or less, exposing the substrate surface to air to form a native oxide layer, removing the native oxide layer to expose the second silicon-containing layer, and depositing a third silicon-containing layer on the second silicon-containing layer. In another embodiment, a method for depositing a silicon-containing material on a substrate surface is provided which includes depositing epitaxially a first silicon-containing layer on the substrate surface with a first lattice strain, and depositing epitaxially on the first silicon-containing layer a second silicon-containing layer with a second lattice strain greater than the first lattice strain.

A method is provided wherein a temperature reading error of a pyrometer is avoided. An upper pyrometer is used to detect infrared radiation from a test layer formed on a test substrate under standard processing conditions. The infrared radiation from the test layer has a period having a length which is indicative of growth rate of the layer. The period is generally inversely proportional to the growth rate. The growth rate is directly related to the temperature.
