Mind Mapping 

 Challenge and Selection 

 I ’m a Mechanical Engineer in semiconductor manufacturing equipment industry , and my day to day   activities include solving field issues and developing new products . In this reflection I will be sharing my   experience on how our team used Mind Mapping tool to solve on wafer non - uniformity and defects . I   wo n’t be sharing details about the project since it is a company confidential data but I will rather be   sharing the approach . 

 Mind Mapping is a great tool to form connections between several modules of a tool and helps give a   better understanding of the overall system . It also helps to guide the project in right direction if we keep   deviating from the goal while working on several level deeper parts of the project . In this example of our   team , we used fish bone diagram to brainstorm and list down all the possible root causes possible and   assigned the team members the tasks to validate the hypothesis for every line item . 

 Application 

 In a semiconductor manufacturing tool there are several modules and sub systems which help in maintain   and control the deposition environment to meet stringent standards for a film deposition over a wafer ,   few of the major characteristics of the film that need to be controlled are the Uniformity of the film ( % NU   - % of Non - Uniformity ) deposited to make sure that the thickness of the film is uniform across the wafer ,   particle defects which is nothing but contamination inside the deposition chamber likes of which can   cause device failure , and several other properties . 

 The challenge to maintain such stringent standard is that the performance of the wafer depends on   several factors given the number of sub systems involved . Our team gathered huge amounts of data   pertaining to the problem and performed root cause analysis using fish bone diagram to dissect the high   level problem into sub - system level trouble - shooting tasks . 

 Insight 

 By making a fish - bone diagram we were able to clearly see and visualize the possible roots of the problem   and assign the probability for it to occur and prioritize the tasks with high probability rate of success . Doing   this also gave a very good understanding to every member of the team and we were able to generate   more ideas to resolve the problems . 

 Approach 

 This course on Coursera , has opened up my approach to product design .    With respect to Mind Mapping , I would definitely use it as often as possible . The key benefits are bringing   out innovative ideas , find patterns and connect them . Also sometimes we zero down on newer ideas   which are amalgamation of the ideas given by different team members . Given the current scenario where ,   time to design to market is shrinking day by day , this tool definitely helps us in concept generation and   sharing our ideas without ambiguity .

### Task: You are a PII (Personal Identity Information) Detection. Given a essays written by students, you have to identify ONLY the following:
NAME_STUDENT - The full or partial name of a student that is not necessarily the author of the essay. This excludes instructors, authors, and other person names.
EMAIL - A student’s email address.
USERNAME - A student's username on any platform.
ID_NUM - A number or sequence of characters that could be used to identify a student, such as a student ID or a social security number.
PHONE_NUM - A phone number associated with a student.
URL_PERSONAL - A URL that might be used to identify a student.
STREET_ADDRESS - A full or partial street address that is associated with the student, such as their home address.
