I got a request to talk about chimney, so today's topic is chimney. Let's talk about it. Chimney is a semiconductor technology to use multiple small dyes to achieve target function, which is supposed to be done by one dice dye. Its goal is to reduce product development time and cost by integrating multiple smaller dyes in a package. A chimney is not a package type and it is part of a packaging architecture. With chimney, dice could be integrated into an existing package type, such as 2.5 d, 3 d, fan out, multi chain modules.<\/p>\n<p style=\"text-align: center;\"><img decoding=\"async\" src=\"https:\/\/file.ab-sm.com\/103\/uploads\/2022\/12\/f17d4bf6501e5826b052117ae8856037.png!a\" alt=\"\" \/><\/p>\n<p>\u5927\u5bb6\u597d\uff0c\u6b22\u8fce\u6765\u5230\u534a\u5bfc\u4f53\u5185\u5bb9\u3002\u6211\u63a5\u5230\u4e00\u4e2a\u8bb2\u8bb2\u5173\u4e8eChiplet\u7684\u8bf7\u6c42\uff0c\u6240\u4ee5\u4eca\u5929\u7684\u8bdd\u9898\u662fChiplet\u3002\u6211\u4eec\u6765\u8c08\u8c08\u5427\u3002Chiplet\u662f\u4e00\u79cd\u534a\u5bfc\u4f53\u6280\u672f\uff0c\u4f7f\u7528\u591a\u79cd\u5c0f\u82af\u7c92\u6765\u5b9e\u73b0\u76ee\u6807\u529f\u80fd\uff0c\u5c06\u539f\u672c\u5e94\u8be5\u7531\u4e00\u4e2a\u82af\u7c92\u6765\u5b8c\u6210\u7684\u4efb\u52a1\uff0c\u5206\u4e3a\u591a\u79cd\u8f83\u5c0f\u7684\u82af\u7c92\u96c6\u6210\u5728\u4e00\u8d77\u6765\u5b9e\u73b0\u3002\u4ece\u800c\uff0c\u51cf\u5c11\u4ea7\u54c1\u5f00\u53d1\u65f6\u95f4\u548c\u6210\u672c\u3002Chiplet\u4e0d\u662f\u6307\u5c01\u88c5\u7c7b\u578b\uff0c\u5b83\u662f\u5c01\u88c5\u67b6\u6784\u7684\u4e00\u90e8\u5206\u3002\u901a\u8fc7chiplet\uff0c\u591a\u79cd\u82af\u7c92\u53ef\u4ee5\u96c6\u6210\u5230\u73b0\u6709\u7684\u5c01\u88c5\u7c7b\u578b\u4e2d\uff0c\u4f8b\u59822.5D\u30013D\u3001\u6247\u51fa\u53ca\u591a\u82af\u7247\u6a21\u5757\u3002<\/p>\n<p style=\"text-align: center;\"><img decoding=\"async\" src=\"https:\/\/file.ab-sm.com\/103\/uploads\/2022\/12\/2a8ad012b75e33012e7e7b102e68c290.png!a\" alt=\"\" \/><\/p>\n<p style=\"text-align: center;\"><span style=\"color: red;\"><strong>\u5fae\u4fe1\u8bc6\u522b\u4e8c\u7ef4\u7801\u89c2\u770b\u89c6\u9891<br \/>\n<\/strong><\/span><\/p>\n<p>Imagine we have one large die and it has CPU, GPU and other functional blocks all in one die as soc system chip. But it is very expensive and there are many challenges to make these clients die. Fortunately, we can have all these functions by multiple smaller dyes. And economically it is more reasonable. But we need to add interface block to each die, so total die area will be more than one dodge die. That is a brief concept of chimney. So chimney is a good solution for large expensive dye, which is typically for high performance computing, rather than for a small die in smartphone.

How it works? This is simple comparison between one dies die and 4 small dies. If there is a defect at the upper left of the die, then it is risen. One die liseth out of one die. So eld is 0. If we have 4 small dies and there is same defect at the exact same location. Then only one die is risen out of 4 dice and eld is 75%. That means we still can save 30 dice. It is more obvious for belly lies die. It also works for a dialogue at the vapor edge. At the left we have dialogues at the wafer ads for large diet. At the right we also have a dye loss, but smaller dye has higher yield than last dye. This is dialed comparison between one die versus chimney with 2,3 and 4 dies. For a 360mm\u00b2 one die we'll have 15% ill but a full chimney design each 99 k millimeters will have 37 yield more than doubles. Even though the total die area of 4 chimney design is more than 10 than one die, the significant yield improvement of chimney is good enough to justify a chimney solution.<\/p>\n<p>Chiplet\u662f\u5c06\u5927\u578b\u7684\u5355\u4e00\u82af\u7c92\u5206\u89e3\u6210\u591a\u4e2a\u8f83\u5c0f\u7684\u82af\u7c92\u3002\u5b83\u662f\u5982\u4f55\u5de5\u4f5c\u7684\uff1f\u8fd9\u662f\u4e00\u4e2a\u5927\u82af\u7c92\u548c4\u4e2a\u5c0f\u82af\u7c92\u4e4b\u95f4\u7684\u7b80\u5355\u6bd4\u8f83\u3002\u5982\u679c\u5728\u82af\u7c92\u7684\u5de6\u4e0a\u89d2\u6709\u7f3a\u9677\uff0c\u5219\u6574\u4e2a\u82af\u7c92\u5c31\u65e0\u6cd5\u4f7f\u7528\uff0c\u6240\u4ee5\u826f\u7387\u662f0\u3002\u5982\u679c\u6211\u4eec\u67094\u4e2a\u5c0f\u82af\u7c92\uff0c\u5e76\u4e14\u5728\u5b8c\u5168\u76f8\u540c\u7684\u4f4d\u7f6e\u5b58\u5728\u76f8\u540c\u7684\u7f3a\u9677\u3002\u7136\u540e4\u4e2a\u82af\u7c92\u53ea\u6709\u4e00\u4e2a\u4e0d\u80fd\u4f7f\u7528\uff0c\u826f\u7387\u4e3a75%\u3002\u8fd9\u610f\u5473\u7740\u6211\u4eec\u4ecd\u7136\u53ef\u4ee5\u8282\u77013\u4e2a\u82af\u7c92\u3002\u5b83\u4e5f\u9002\u7528\u4e8e\u8fb9\u7f18DIE\u3002\u5728\u5de6\u8fb9\uff0c\u6211\u4eec\u6709\u5927\u91cf\u65e0\u6cd5\u4f7f\u7528\u7684\u8fb9\u7f18DIE\u3002\u5728\u53f3\u8fb9\uff0c\u6211\u4eec\u4e5f\u6709\u76f8\u7c7b\u4f3c\u7684\u635f\u5931\uff0c\u4f46\u8f83\u5c0f\u7684\u82af\u7c92\u6bd4\u8f83\u5927\u7684\u82af\u7c92\u5177\u6709\u66f4\u9ad8\u7684\u826f\u7387\u3002\u8fd9\u662f\u4e00\u4e2a\u82af\u7c92\u4e0echiplet \u7684\u67092,3\u62164\u4e2a\u82af\u7c92\u4e4b\u95f4\u7684\u6bd4\u8f83\u3002\u5bf9\u4e8e360mm\u00b2\u7684\u4e00\u4e2a\u82af\u7c92\uff0c\u6211\u4eec\u4ec5\u670915%\u7684\u826f\u7387\u3002\u4f46\u9488\u5bf94\u4e2a\u82af\u7c92\u7684chiplet \u8bbe\u8ba1\uff0c\u826f\u7387\u5c06\u662f\u524d\u8005\u7684\u4e00\u500d\u4ee5\u4e0a\u3002\u5373\u4f7f4\u4e2a\u82af\u7c92\u7684chiplet \u8bbe\u8ba1\u7684\u603b\u9762\u79ef\u6bd4\u4e00\u4e2a\u5927\u82af\u7c92\u591a\u51fa10%\uff0cChiplet\u7684\u8bbe\u8ba1\u660e\u663e\u63d0\u9ad8\u4e86\u826f\u7387\u548c\u5408\u7406\u6027\u3002<\/p>\n<p style=\"text-align: center;\"><img decoding=\"async\" src=\"https:\/\/file.ab-sm.com\/103\/uploads\/2022\/12\/c99a62d9cc04db352cf87ae1af2b31a5.png!a\" alt=\"\" \/><\/p>\n<p>Back in 2014 fpga company gidings made vertex 72000 t and it used 4 smaller chimney dyes rather than one.
