"The use of a new generation of InP semiconductor (indium phosphide) optical communication era will come.Deal with a new technology is still to come work definitely interesting."

This is once in university period has studied InP brother give me advice.I agree with the idea, hence induction in sumitomo electric industries, hope in the compound semiconductor InP on related work, and was assigned to the semiconductor division.Compound semiconductor is widely used in everything from smartphones to industrial machinery field, is indispensable to our daily life.As the circuit boards of the wafer is to from the material of the columnar crystal growth block (ingot) after thinly slice.Up to now为止，我一直从事切片相关工作，包括新切割设备的设置、特殊产品切片流程的开发等。

Expensive compound slicing process need to handle, so the difficulty is how to reduce losses, how to stabilize extract as much as possible the wafer (substrate).When young, supervisor, predecessors and technical personnel to give me a lot of help, at the same time, I actively participate in the business, when purchasing a cable, besides, head of the business, also negotiate with engineers, to collect information.And based on the information processing samples, analyze data, applying PDCA circulation *, in order to grasp the features of equipment and materials.

InP section must possess high precision Angle, when it left a deep impression on me.When use the machine without access to the required precision.So I will consider the introduction of new machines and improve processes, and pleaded with the director to implement it.My proposal of the investment amount is huge, but even so, the factory director and please come to the manufacturer, the next day decided to import the machine.

Initially did not obtain the expected results, I can only alone, then I Shared with team members after optimization in the process of solving problems, after their feet on the ground of continuous improvement, and finally achieve the target accuracy.To it as an opportunity, I deeply realized as long as the collaboration with his companions, so any problems can be solved.I firmly believe in the value of close communication at the same time, build up the team members to be able to play each other, learn from each other's environment, can promote the business to improve, maintain high quality of the product.

* PDCA Plan/program, the Do/implement and Check/evaluation, the Action/improve the acronym.Is a kind of cycle through the four o 'clock to continue to improve management of business

The object products, the compound semiconductor cutting conditions and equipment will also be different.When cutting, need to use made of cable wire saw this kind of equipment, request the cables can be according to the product characteristics, rapid, precise and stable to cut materials.To this end, I asked manufacturer detailing the required cable condition, finally successfully developed the fine line cable cutting technology, new materials before that there is no successful cases.In addition, also successfully developed a new chip technology based on the latest cutting device.These development efforts to reduce the cost and reduce the waste of materials, has received the high praise, the company think me important skills, will my certification for experts in 2015.

But along the way, also has not all been plain sailing.In order to improve the business and promote the process of development, numerous, of course, also there is a failure.Let me remember, above all, I have placed as material of special crystal errors in cutting machine, led to a huge amount of defective goods loss for the first time.This mistake due to I had other synchronous operation, I feel depressed.Of course, I have already prepared to be scolded by your boss, but to his surprise, the boss said to me: "in the process of effort is hard to avoid can make mistakes.Fear of failure loss improvements will, it is very bad for the company more.Hope you can in the future do not fear failure, continue to improve."

Today, these words are still rooted in my mind, as an expert in training successors and other occasions I always keep in mind, too.

I remember the boss's comments, so when cultivating successors, also can avoid the "blame".Work progress not smooth, communication should be repeated until find out the influencing factors of job, and a solution to a task.At this point, in addition to factory workers, junior must also be related to the technical staff, all staff to share information in real time.See them in the process, to master the skills we need to provide guidance to others and form professional consciousness, I was very with a sense of accomplishment.Each person's individual character each are not identical, according to its character according to their aptitude, it is very important.From this perspective, I as a mentor and receiving training in daily.

Now, I am engaged in the production, while carries on the related development can promote the business to improve, and dedicated to the new culture.Can progress every day, because I have intention to have the courage to challenge and as manufacturing professional pride.In addition, daily will improve the goal and its implementation in practical action, to work with people around you to achieve your goals, continuous efforts at the same time, it is my belief.Manufacturing is not fight alone, it always need team cooperation, so the relationship with colleagues is very important.I hope to improve the working environment, flexible prepare to cope with the evolution of the world, continue to technology to challenge the limits of the world.The process will inevitably appear many trouble, but these troubles can improve yourself eventually skills, can also be used to realize a pleasure.

Now, I am still committed to the development of a new technology and to act.As soon as possible if you can develop the technology, is expected to be an unprecedented reduce costs and improve productivity.I firmly believe that insist on manufacturing while improving, can realize the evolution of the manufacturing site.
