DETAILED ACTION
Notice of Pre-AIA or AIA Status
The present application, filed on or after March 16, 2013, is being examined under the first inventor to file provisions of the AIA .
Claim Rejections - 35 USC § 102
In the event the determination of the status of the application as subject to AIA 35 U.S.C. 102 and 103 (or as subject to pre-AIA 35 U.S.C. 102 and 103) is incorrect, any correction of the statutory basis (i.e., changing from AIA to pre-AIA ) for the rejection will not be considered a new ground of rejection if the prior art relied upon, and the rationale supporting the rejection, would be the same under either status.
The following is a quotation of the appropriate paragraphs of 35 U.S.C. 102 that form the basis for the rejections under this section made in this Office action:
A person shall be entitled to a patent unless –
(a)(1) the claimed invention was patented, described in a printed publication, or in public use, on sale, or otherwise available to the public before the effective filing date of the claimed invention.

Regarding Claim 9, the apparatus further comprises: a printed circuit board; and a first integrated circuit component attached to the printed circuit board, the first integrated circuit component comprising the substrate, the first layer, the second layer, and the third layer.
Regarding Claim 10, in paragraphs 0032 and 0038, the apparatus further comprises one or more second integrated circuit components attached to the printed circuit board.
Regarding Claim 11, in Figs. 1, 8a and 8b and paragraphs 0026-0049, Glushenkov et al. discloses.an apparatus, comprising: a substrate 102 comprising silicon (paragraph 0027); a first layer 106 positioned adjacent to the substrate (paragraph 0045), the first layer comprising boron, silicon and germanium (see paragraph 0045); a second layer 402/602 positioned adjacent to the first layer, the second layer comprising gallium (see paragraph 0043 and 0044); and a third layer 802 positioned adjacent to the second layer, the third layer comprising a metal (see paragraph 0048).
Regarding Claim 12, a concentration of gallium in the second layer is within a range of 5E19 to 5E20 atoms/cm3. (see paragraphs 0039 and 0040)
Regarding Claim 13, the first layer comprises epitaxially grown boron doped silicon germanium and the second layer comprises epitaxially grown boron doped silicon germanium with a higher concentration of germanium than the first layer (see paragraph 0035)
Regarding Claim 14, an atomic percentage of gallium in a portion of the second layer below a top two monolayers of the second layer is less than five percent (see paragraph 0050)
Regarding Claim 15, the third layer comprises at least one of titanium, nickel, platinum, cobalt, or tungsten (see paragraph 0047).
Regarding Claim 16, in Figs, 1-8b and paragraphs 0026-0049, Gluschenkov et al. discloses. a method, comprising: forming a first layer 106 comprising boron, silicon, and germanium (paragraph 0045), the first layer positioned above a substrate; forming a second layer 402/602 positioned adjacent to the first layer, the second layer comprising gallium (see paragraphs 0043 and 0044); and forming a third layer 802 comprising metal, the third layer located on the second layer (see Fig. 8a/8b, elements 802 and 402/602).
Regarding Claim 17, in paragraph 0037, forming the second layer comprises applying triethyl gallium on the first layer.
Regarding Claim 18, in paragraph 0037, forming the second layer comprises applying trimethyl gallium to the first layer.
Regarding Claim 19, in paragraph 0035, forming the second layer comprises applying a precursor comprising gallium to the first layer at a temperature of between 375 and 500 degrees Celsius.
Regarding Claim 20, a concentration of gallium in a portion of the second layer is within a range of 5E19 to 5E20 atoms/cm3. (see paragraph (see paragraphs 0039 and 0040).
Examiner is including following pertinent prior art references that are NOT relied upon but that do disclose the usage of gallium layer to lower contact resistance.
