Unbelievable, foreign big cattle own DIY chip

This thing is more impressive, Sam Zelov (Sam Zeloof) is building a well-equipped semiconductor manufacturing laboratory. Is it very incredible? SAM often publishes his progress on its own blog and Twitter. He taught the semiconductor physics course at the 2018 SuperConference meeting, and how he became the first amateur enthusiasts using a photolithography process. SAM did not elaborate his origin of interest to DIY IC, but it can be seen from a short tour from his Youtube channel. This should be the recent years. In 2016, this store does not seem to include any device required for SAM to achieve its dreams - high vacuum room, turbo molecule pump, tubular furnace, chemical laboratory, and optical and electron microscopy. Sam swaying in the speech, it seems that there is nothing big deal. Although these devices are easy to get, it is relatively easy, but knows how to deal with another thing. The first part of the SAM speech is a review of semiconductor physics, ensuring us, he has accepted the education required to use tools to use. SAM's first semiconductor, simple PN junction diode and photovoltaic technology, which have appeared in this process. His first MOSFET was born in early 2017, and approximately when he pays attention to his homemade factory laboratory. However, compared with his thoughts, these early success only warm up. SAM wants to use the same lithography technique as the commercial chip factory to manufacture ICs. He must learn how to handle silicon wafers, heat treatment to form an oxide layer, using its own DLP projector to pattern the pattern, and finally have to work hard, get a result: "That is z1" chip, a PMOS double difference amplifier . SAM said that the manufacturing process takes a total of approximately 12 hours, although he did not use the soldering machine to be installed on the lead frame, the chip has been tested and can work.
