ENTROPY LTD LLC

   WHAT WE DO:  We find simple and cost effective solutions for the Semi Conductor, Laser, Telecommunications, optics and Bio Medical industries where manufacturing and process yields are low or out of control.

  HOW:   We use our 32 years of technical experience in manufacturing, sustaining, R&D and process engineering combined with analytical chemistry, ultra high vacuum technology and materials science.

   NOTHING SUCCEEDS LIKE SUCCESS

   We have a proven record of better than 99% success.

   Below are examples of the problems our clients encountered and briefly how we solved their problem.

 OUR SUCCESSES: 

A laser company

     Unstable high power lasers:  examination of the interface layer between di electric layers using TOF SIMS (a powerful, highly sensitive way to measure the chemical composition on a surface) to discover that residual detergent remained and was causing absorption of the laser radiation. This translated into thermal energy resulting in physical distortion of the optic.

       Here careful intepetation of the results along with systematic examination of the manufacturing process was necessary to piece the puzzle together. This enabled a new and better cleaning process to be implemented saving the company money and improving market credibility.

A semi conductor company:

       $500,000 Power worth of supply chips remained high after routine mil spec testing.

        Here compilation of many variables was necessary to solve this puzzle.  Electronic testing showed capacitance behavior before testing and resistive afterwards. Review of the schematic along with analysis of the depth of resistor implantation provided a framework for a working theory.  Subsequent chemical analysis of the surface showed highly moblie ions causing implanted resistor values to change.

        Again, improper chemical cleaning of the materials used to manufacture this IC chip. Review of the process, chemical analysis, experiments and materials investigation resulted in finding a worable solution. In this case a simple modification of the process allowed many of the IC's to be used saving the company more than half of the original $500,000 that was thought irretrivable.

 A BIO MEDICAL Laboratory:

       A quantitative DNA fluorescence assay was hampered from a high background from residual hydrocarbon on the fused silica fibers used to conduct the test.

      Here once the hydrocarbon was identified as polyimide, a high temp , highly durable polymer. Efforts to find alternative methods to chemically remove this polymer from the glass were begun.

      Two new methods were discovered enablng the manufacturer to assay DNA with a 1000 fold reduction in background.

A Laser Company:

      Processing of a laser using standard ultra high vacuum (UHV) techniques left large (5%) moisture in the ceramic laser housing.  Since epoxy seals were used temperatures greater than 100 C were not feasible. Development of a higher temperature seal was not within the budget.

      Here the use of a novel approach to vacuum processing was required. Viscous flow processing is a rarely used but highly effective method to reduce residual moisture within a electro optical package by more than 1000 times as compared to standard UHV methods.

       A simple yet highly effective system was desiged and built that employed viscous flow principles.  Residual moisture was shown to be reduced to less than 60 ppm ~ 1000 times reduction in water vapor. 

       These few examples of our success should help you to understand what we can do and our versatility in finding solutions.  Other work involved: UHV system design, chemical cleaning systems, improvements to diode lasers, materials investigation of NLO (non linear optical) materials.  With real world engineering experience coupled with chemistry and material science ENTROPY LTD LLC is a recognized leader in finding simple solutions for your manufacturing problems

        Other examples: Simple in line process measure to prevent improper filling of argon ion lasers, process improvements to a brazing operation increasing yields from 40 % to 95 %, improvement in optical sealing method resulting in reduction of warranty exposure from 40 % to less than 3 % in less than 3 months.

What We Do

      Entropy LTD LLC offers a range of services from process consulting to materials investigations to chemical analysis (using outside services)  with UHV system design, Chemical cleaning and Viscous Flow Processing.

       When a company encounters an "intractable" manufacturing or development problem ENTROPY LTD LLC can provide technical consulting services. 

       We offer a systematic and highly analytical approach to problem solving. Using state of the art surface and bulk chemical analytical methods in combination with our experience it has been possible to find solutions to these "intractable" problems rendering them solved.
