`Exhibit 1015

`AVX CORPORATION

`
`
`
`1.
`
`I, Randall Lewis, resident at 280 Greenwood Road, Afton, Tennessee,
`
`hereby declare as follows:
`
`2.
`
`I am a scanning electron microscopy (SEM) engineer for AVX
`
`Corporation in Fountain Inn, South Carolina. I have held this position since July
`
`of 2005 and have over 38 years of experience in the field of physical analysis of
`
`electronic components including capacitors. My principle job is to evaluate
`
`components being developed by the Advanced Products and Technology group.
`
`As part of my employment at AVX Corporation and in my role as SEM engineer, I
`
`routinely cross-section (or otherwise deconstruct) electrical components such as
`
`multi-layer ceramic capacitors and analyze those electrical components using a
`
`scanning electron microscope and associated hardware and software tools.
`
`3.
`
`In early January of 2017, I was provided with a reel of capacitors by
`
`Mr. John Galvagni, and was asked to assist in analyzing the physical dimensions
`
`and other properties of several samples of the capacitors on each reel. I selected
`
`three sample capacitors from the reel provided by Mr. Galvagni. To prepare the
`
`samples for SEM analysis, as is my typical habit, I cased each of the sample
`
`capacitors on a mount in a two part acrylic epoxy called Castamount, which is
`
`purchased from Pace Industries. The samples were each placed in a same
`
`orientation according to their external electrodes, and the mount was labeled with
`
`2
`
`000002
`
`
`
`the date on which the mount was prepared. Samples of the capacitors provided by
`
`Mr. Galvagni were the only samples mounted on that date. After the Castamount
`
`epoxy cured, the sample capacitors from Mr. Galvagni were sectioned to reveal a
`
`cross-sectional area suitable for visible analysis with a scanning electron
`
`microscope. For the sectioning, as is my typical habit, I used an Allied High Tech
`
`MultiPrep grinder and polisher and carbide sanding paper purchased from Allied
`
`High Tech. This process used to mount and section the sample capacitors from
`
`Mr. Galvagni is the same process I routinely use in my role as SEM engineer for
`
`critical destructive physical analysis requests of electrical components. I have
`
`performed sample preparations such as this approximately 3,000 times in my
`
`career at AVX, and the results of my preparation and subsequent analysis are
`
`regularly relied upon by me and others at AVX during the normal course of
`
`business.
`
`4.
`
`After completion of the mounting and sectioning process, I witnessed
`
`Mr. Galvagni take photographs of the respective cross-sections of each sample
`
`capacitor with a Zeiss Axio Imager Optical Microscope. After these initial
`
`photographs were taken, the sample capacitors were prepared for scanning electron
`
`microscope evaluation of the dielectric grain structure between internal electrode
`
`layers. To prepare the sample capacitors for this analysis, I placed the mount onto
`
`an aluminum stub using conductive carbon adhesive and aluminum adhesive strips.
`
`3
`
`000003
`
`
`
`The mount and the aluminum stub were then placed in a Denton Vacuum Desk-1
`
`chamber and degassed and sputter-coated for 30 seconds with gold-palladium.
`
`This process used to prepare the samples for scanning electron microscope
`
`evaluation is the same process I routinely use in my role as SEM engineer for
`
`preparing samples for such evaluation. I have performed sample preparations such
`
`as this approximately 3,000 times in my career at AVX, and the results of my
`
`preparation and subsequent analysis are regularly relied upon by me and others at
`
`AVX during the normal course of business.
`
`5.
`
`The gold-palladium coated capacitors and mount were then placed in
`
`a Zeiss Sigma field emission scanning electron microscope (SEM) with which I
`
`reviewed each of the samples of the capacitors provided by Mr. Galvagni. The
`
`dielectric layers were the same for each of the three samples of the capacitors
`
`provided by Mr. Galvagni both in numbers of grains per layer and approximate
`
`size of the grains themselves. I took magnified photographs of the dielectric grain
`
`structure for sample 2 of the sample capacitors provided by Mr. Galvagni using a
`
`Carl Zeiss Backscatter Detector at 5,000 times magnification and at 20,000 times
`
`magnification. I selected sample 2 because it offered the clearest photographs
`
`from the three samples of the dielectric grain structure. This sample 2 is the same
`
`sample as the sample 2 capacitor to which Mr. Galvagni refers in his declaration. I
`
`personally provided the following photographs of sample 2 to Mr. Galvagni on a
`
`4
`
`000004
`
`
`
`thumb drive, the first of which is taken at 5,000 times magnification and the
`
`second of which taken at 20,000 times magnification:
`
`
`
`5
`

`
`

`
`The measurement software overlaid the 1 μm and 200 nm scales,
`
`respectively, in the bottom, left corners of the above photographs. The SEM and
`
`measurement software are calibrated annually by a service technician from the
`
`manufacturer (i.e., Zeiss) to ensure the continued accuracy of these overlaid
`
`measurement scales.
`
`7.
`
`I hereby declare under penalty of perjury under the laws of the United
`
`States of America that the foregoing is true and correct, and that all statements
`
`made of my own knowledge are true and that all statements made on information

`
`I understandthat willful false statements and the
`
`like are punishablebyfine or imprisonment, or both (18 U.S.C. § 1001).
