By Tom Hawking Published April 21, 2026, 3:40 pm ET Reading time 3 minutes Dr Semiconductor and DIY RAM Necessity is the mother of invention, and the RAM crisis is driving people to some pretty creative measures to avoid paying through the nose to upgrade their computer’s memory. Recently, we covered one man’s brave attempts to run a computer without RAM—spoiler, that idea is kind of a non-starter—and now a YouTuber who calls himself Dr Semiconductor has upped the ante by building functioning memory cells himself… in his garden shed. I honestly thought the title of this video was a joke until I started watching, and it’s hard to overstate how wild this is. This isn’t a case of soldering together a few logic gates—this guy has managed to construct a semiconductor fabrication setup in the sort of shed that looks like it should be hosting a rusty lawnmower, a few half-full cans of paint, and a wheelbarrow with a flat tire. In a video released last month, the good doctor catalogued the construction of his DIY cleanroom, and in the follow-up video, he narrates the process of putting together a functioning RAM cell. 觀看一位男子在自家花園小屋裡製造出可工作的微米級隨機存取記憶體 (RAM) 單元 真的。 湯姆 霍金 發佈於美國東部時間2026年4月21日下午3:40 閱讀時間：3分鐘 半導體博士和DIY RAM 需求是發明之母，而記憶體危機正迫使人們採取一些極具創意的措施，以避免花大錢升級 電腦記憶體。最近，我們報道了一位男士大膽嘗試在沒有內存的情況下運行電腦——劇透 一下，這個想法根本行不通—現在，一位自稱“半導體博士”的YouTube博主更進一步 ，竟然在自家花園小屋裡親手製作出了能用的內存單元。 https://youtu.be/h6GWikWlAQA 說實話，我一開始以為這個影片的標題是個玩笑，直到我開始看才意識到，這簡直太瘋狂 了。這可不是簡單地焊接幾個邏輯門—這傢伙居然在一個看起來像是放著生鏽割草機、 幾罐半滿油漆和一輛爆胎手推車的破舊棚子裡，搭建了一套半導體製造設備。在上個月發 布的影片中，這位「好心人」詳細記錄了他自製無塵室的搭建過程，而在後續的影片中， 他又講解瞭如何組裝一個能正常工作的RAM單元。 https://youtu.be/HfSO-LCKmrA If you’ve ever wondered how modern chips are fabricated, the video doubles as a pretty great description of the process. The good doctor explains each step as he goes, walking us through the deposition of the initial oxide layer on the silicon wafer, then the processes of photolithography, etching, thin-film deposition, and testing. These processes use some pretty gnarly chemicals to clean the chips and strip away unneeded material. And if you’re familiar with chip fabrication and find yourself wondering whether he uses hydrofluoric acid and piranha solution: Hell yes, he does. (There’s no sign of the delight that is chlorine trifluoride, though, perhaps because getting hold of it puts you on all manner of watch lists.) The video also provides an excellent explanation of how RAM cells actually work. One thing that you might not know—I certainly didn’t until fairly recently—is that current drains constantly from RAM cells, which means they need constant recharging. Dr Semiconductor’s cells need recharging every couple of milliseconds, but as he explains, even commercial DRAM needs to be recharged every 64 milliseconds or so. This is why RAM is volatile, and doesn ’t retain data when you turn your computer off. (As an aside: computer science YouTuber Laurie Wired recently made an excellent video about why RAM works like this.) 如果你曾經好奇過現代晶片是如何製造的，這段影片正好可以作為整個流程的絕佳講解。 這位博學的博士一邊示範一邊解釋每個步驟，從矽片上沉積初始氧化層，到光刻、蝕刻、 薄膜沉積和測試等工序，一一講解。這些工序需要用到一些非常刺激的化學物質來清洗晶 片，去除多餘的材料。如果你熟悉晶片製造，並且好奇他是否使用了氫氟酸和食人魚溶液 ：沒錯，他確實用了。 （不過，他並沒有提到三氟化氯，或許是因為使用這種物質會讓 你被列入各種監視名單。） 這段影片也對RAM單元的工作原理做了很好的解釋。你可能不知道的一點——我直到最近 才知道—是RAM單元會不斷消耗電流，這意味著它們需要不斷充電。半導體博士的RAM單 元每隔幾毫秒就需要充電一次，但正如他解釋的那樣，即使是商用DRAM也需要大約每64毫 秒充電一次。這就是為什麼RAM是易失性的，在你關閉電腦時不會保留資料。 （順便一提 ：計算機科學YouTuber Laurie Wired最近製作了一個很棒的視頻，解釋了RAM為什麼會這 樣工作。） https://youtu.be/KKbgulTp3FE Anyway, by the end of the video, Dr Semiconductor has a few fully functioning RAM cells, each of which is in the order of microns in size. And again: this is insane. There are other channels on YouTube where people have successfully put together home photolithography setups, but actually producing functioning RAM with micron-scale cells is a whole other level. Of course, it’s not like the Doctor has magicked up several gigabytes of RAM—this video is basically a proof of concept, something its creator readily admits. However, it sounds like he’s not done—he ends the video by explaining his plans to “take these cells, stitch them together … and hook [them] up to a PC.” If you’d asked me yesterday whether this was remotely possible, my answer would have been “lol no.” But now? I mean, I wouldn’t bet against him. 總之，在影片結尾，半導體博士已經製作出幾個功能齊全的RAM單元，每個單元的尺寸都 在微米級。再說一次：這簡直太瘋狂了。 YouTube上也有其他頻道成功搭建家用光刻設備 ，但真正用微米級單元製造出可用的RAM，完全是另一個層次的技術。當然，這位博士並 沒有憑空變出幾GB的RAM—這段影片本質上只是一個概念驗證，其創作者也坦然承認這 一點。不過，他似乎還沒完—視頻結尾，他解釋了自己的計劃：“把這些單元拼接起來 ……然後連接到電腦上。” 如果你昨天問我這事有沒有可能，我的回答一定是「哈哈，不可能」。但現在呢？我的意 思是，我不會再跟他打賭他做不到了。 5.完整新聞連結 (或短網址)不可用YAHOO、LINE、MSN等轉載媒體: https://reurl.cc/DxqY3e 6.備註: 美國人的車庫果然從核設施到隨機存取記憶體都能搓出來... -- http://www.youtube.com/watch?v=m-QXmqX7k8Q 劉德華 悟 電影【新少林寺】主題曲 https://youtu.be/dLRLWy7bKS4 作曲：趙欽 作詞：劉德華 《金剛總持祈請文》 編曲：Adam Lee．飾墜．陳德建 蔣巴桑波 (第七世噶瑪巴確扎嘉措之根本上師) 著 監製：陳德建．李安修 不要把金王冠織入鳥巢中 招惹微風與獵槍是不明智的 依常斷見所立宗 能壞慧命因緣法 精勤十善一夜盡 縱生天人多闡提 -- ※ 發信站: 批踢踢實業坊(ptt.cc), 來自: 1.34.17.2 (臺灣) ※ 文章網址: https://webptt.cc/bbs/Gossiping/M.1776827172.A.712.html
