I've done whatever I want

Facing the bright sunshine in July, the powerful Mercedes-Benz sedan drove quietly in the bustling streets of Shanghai. Irene spent a period of her childhood in this city. The scenery outside the window made her feel very friendly and happy. Very down to earth.

Great Shanghai, this time I am really back!
The grandparents, who are over 80 years old, are still in good health. They hold a sun umbrella together and wait eagerly for her return in the ancient alley.

Under the sun, when their only granddaughter jumped out of the Mercedes-Benz car and ran towards them, the old people were so excited that they burst into tears.

My son Li Du was very proud and went to the United States to study for a Ph.D. After graduation, he immigrated to the United States and married a beautiful white man. For a long time, they felt very proud deep down and felt very respectable in front of their neighbors. .

However, as they grow older, that kind of stubborn pride is gradually replaced by cold loneliness. The disadvantages of not having their only child around gradually become prominent in their lives, especially when they are sick and lying in white in the hospital. On the hospital bed, the strong longing for their loved ones will permeate the entire gray sky of the elderly, making them feel depressed.

After the age of 80, their physical functions decline rapidly. What the old couple talk about most is who will leave first. People entering their twilight years are full of fear in their hearts about something as taboo as death. .

The beautiful and sunny granddaughter was about to return to them, and they suddenly felt that the musty sky in their hearts was filled with the warm sunshine of spring.

"Eileen, my heart! My baby!" The old grandma was very excited as she was hugged tightly by her granddaughter.

She felt as if she had caught a driftwood of fate in a river of time that was full of despair and rushing forward without turning back. She felt warm and fulfilled inside.

"Hello, grandparents!" Xin Tong smiled brightly and greeted the elderly people politely.

The old people had met Xin Tong a long time ago, and they were full of good impressions of this young man who graduated from Shanghai Jiao Tong University.

If the only granddaughter was not taken away by the wealthy Jews on Wall Street and married to an outstanding Chinese, all they had to do was applaud and agree.

"The sun is shining brightly outside, let's go back and sit inside!" the old man said.

The bright sunshine in July passed through the dense leaves of the camphor tree, quietly shining on the old villa where the old man lived. In the yard that had been quiet for a long time, there were songs and laughter again that day, and the warmth of home returned.

The jet lag between the two was very fast. The next day, they set off in high spirits early in the morning and drove to Suzhou in a Mercedes-Benz car.

"Eileen, the acquisition of Wuji Semiconductor was the most beautiful thing I did last year!" Xin Tong said proudly while driving on the highway.

"Really?" Irene asked knowingly. She tilted her head and looked at Xin Tong innocently.

"This company's annual output value can reach 3000 million, and its profit can reach 1000 million. I only spent [-] million to win it. According to the dynamic price-earnings ratio, it is worth at least [-] million!"

"Oh my god!" Erin's eyes widened.

"Every economic crisis is an excellent opportunity to redistribute wealth. Smart investors buy when no one cares about it and sell when there is a lot of buzz!"

"Dear Tong! You know so many things!"

"As for investment, I'm trying to trick you! But I still have a certain say in semiconductor technology. Logitech is researching copper wire technology, and we are not short of money. According to economic laws, there will be changes in the semiconductor industry in the future. After a few good years, I plan to increase investment in the packaging and testing factory." Xin Tong was eloquent when talking about the company's future plans.

"I support you!"

They were chatting while driving and unknowingly arrived at Wuji Semiconductor.

That day, Logitech was instructing the copper wire process in the FOL dust-free workshop. Xin Tong did not communicate with him in advance. When he learned that Xin Tong had arrived at the company, he immediately took off his electrostatic clothes and walked out.

In the small conference room, Xin Tong and Irene were discussing something.

When Logi entered the door, he was stunned. Although Xin Tong called him last time and told him about his successful proposal in the United States, what he saw in front of him still made him unbelievable.

Pictures from six years ago kept popping up in his mind. A bonding process operator who could speak English caught his attention and was promoted to a technician by him.In six years, Xin Tong used his wisdom and sweat to fill the huge gap between him and the billionaire's daughter!
"Boss Xin, you are here!"

"Yes!"

Logitech has long been familiar with the Princess of Moonlight.

"Erin, good morning!"

"Logitech, good morning! With you at Wuji Semiconductor, I feel at ease!" Irene smiled lightly.

For this father's former confidant, Erin had already heard about Logitech's technical capabilities.

"Mr. Luo, today is Eileen's first time coming to Wuji Semiconductor. We want to visit the dust-free workshop." Xin Tong said as he stood up.

"Okay, I'll take you down to the workshop to have a look!"

Logitech was very excited. Xin Tong had just returned from the United States. The jet lag hadn't completely reversed before he came to Suzhou to guide the work. He had to leave the workshop as soon as he arrived in Suzhou. He is really a practical entrepreneurial boss.

He has stayed at Ming Yueguang for more than ten years and rarely sees Dr. Li Du out of the workshop. Every time Dr. Li comes to Shanghai, he always organizes management meetings to review work plans.

"Lao Luo, I want to see how the copper wire process you developed is progressing now?" Xin Tong asked with concern as they walked towards the workshop.

"This process is not mature yet, and cratering problems are prone to occur during the copper wire bonding process," Logitech said.

"The crater problem?"

"Yes, I'll take you to the laboratory to have a look!" With that, Logitech led the two of them to the reliability laboratory.

The most eye-catching thing in the laboratory is the high and low experimental boxes. Wuji Semiconductor already has the experimental capabilities for environmental stress projects defined in the JEDEC standard.

"Xiao Lin, please bring me the sample of the copper wire process that has just been completed in the bonding process!" Logitech shouted in the laboratory.

When he arrived at the production workshop, Logitech became a general giving orders.

"Okay!" Experimental engineer Xiao Lin took an electrostatic bag in his hand, which contained five newly bonded chips.

"Boss Xin, if the molding process has been completed, we will also arrange for the chip to be decapped to remove the plastic sealing material on the outside. We can just use these samples that have not been molded for rot ball analysis!" Logitech turned to Xin Tong said.

"Okay!" Xin Tong nodded.

"Xiao Lin, boil the KOH solution in the beaker first, and then soak the chips in the boiling KOH solution for 3 to 5 minutes. Observe the surface of the chips. Don't corrode the pads. You must pay attention during the experiment. Pollution control of exhaust gas." Logitech turned around and told experimental engineer Xiao Lin.

"Okay!" Xiao Lin nodded.

"Boss Xin, after Xiaolin uses the boiling KOH solution to corrode the copper wire, we can use a high-power microscope to observe the pads bonded with the copper wire process to see if there is any crater problem." Logitech turned around and said.

"Okay!"

After Xin Tong finished speaking, he followed Xiao Lin to the place where rot ball analysis was done. Although the chemical analysis room had been strictly protected, a sour smell could still be smelled in the air.

Xiaolin carefully used metal tweezers to put the chips one by one into the boiling KOH solution. The acid kept rolling. After 3 minutes, the copper wire disappeared and the naked die appeared in front of everyone.
