Process Improvement Engineer (Temp)

On a contractual assignment, responsible for improving the

night vision image intensifier (micro-channel plate)

production yield. Some notable improvement activities were:

- Process Improvement : Introduced a 60 mega-pixel machine

vision systems for in-line inspection of glass fibers for

defects such as fiber non-uniformity, fiber separation,

cracks, scratch, saw marks, etc. Previously done manually

using a 4x eye loupe.

- Root Cause Analysis: Introduced the use of pad

conditioning methods for reducing micro-scratches caused

by the optical polishing process and previously attributed

to operator function.

- Continuous Improvement: Customized an in-house, and cost-

effective, bench-top micrometer for the measurement of

plate diameter on a consistent and repeatable way with

data logging capability. Moreover, setup SPC charts

related to this measurement.

- DMAIC: Extensive DOE to optimize the chemical processing

(acid/base chemistry) in order to improve yield (hot

spots, glow, leakage). Input variables for the DOE were

chemical temperature, residence time, and acid/base

concentration.

- Gap Analysis: Prepared an extensive report for

presentation to upper management on gap analysis between

the Texas and Arizona sites for sharing and improving

product yield.

- Poka Yoke: Implemented On-the-Job training(OJT)

certification, training videos, engineering drawings, and

flow charts for the entire manufacturing area.

2005 - 2008 ST Microelectronics, Dallas, TX

Manufacturing Process Engineer

As a senior process engineer responsible for sustaining the

low pressure thin film deposition equipment used in IC

fabrication. Films deposited were silicon nitride, and tetra-

ethyl ortho silicates(teos) using low pressure chemical

deposition. In addition, extensive experience with coating

surfaces with polyimide films such as PMMA (poly methyl

methacrylate) and curing such films in vacuum ovens.

Excellent understanding of these polymeric films in terms of

material properties and application. Daily adjustments to

process variables, handling of out-of-control products,

process trouble shooting, mentoring junior engineers and

technicians, and training operators. Hands on experience with

DOE, SPC, FMEA, and documentation.

2003 - 2005 Photronics Inc, Allen, TX

Engineering Group Leader - Yield Enhancement and Defect

Reduction

Supervised two engineers and four technicians in charge of

plant scrap reduction activities. Moreover, also

responsible for investigating customer returns, failure

analysis, FMEA, 8D, and SCAR reporting.

Within a one year period, produced the highest product

yield ever attained at that site for a particular process

operation through detailed characterization and

improvements.

Carried out several failure analysis studies and 8D reports

on product returns. Failure analysis involved use of

detailed lab evaluations using FTIR, EDX, and SEM

techniques to understand process changes implemented by

customers that may have resulted in early failure.

Developed and implemented a comprehensive ESD control

strategy for the entire plant that ranged from monitoring

DI water resistivity to air ionization measurements.

2000 - 2003 Texas Instruments, Dallas, TX

Sr. Surface Coating Process Engineer (Chemical Vapor

Deposition)

Process development and sustaining of chemical vapor

deposition batch reactors used for the deposition of thin

films (coatings, etc). Some of the films deposited included

silicon

dioxide, silicon nitride, oxynitrides, polysilicon, tetra-

ethyl ortho silicates, etc. Involved in several major cost

reduction projects requiring process optimization and

reduction of chemical usage. Experience in failure analysis

with materials analysis methods such as SEM, TEM, TXRF,

EDAX, and Secondary Ion Mass Spectroscopy. Extensive use of

DOE.

1996 - 1999 Motorola, Austin, TX

Process Development Engineer

As a process engineer, developed several key coating

processes using photo-sensitive polymeric materials

containing diazo-naphtoquinones, tert-butyl phenols, bis-aryl

azide,

and so forth. These photo-sensitive films (resists) were

applied to surfaces of micron scale electronic components

for subsequent optical lithography. Extensive use of design

of experiments and statistical process control. hands on

experience with polymer and solvent delivery systems (pumps,

bulk filling, nozzles, etc).
