图1：半导体 的 生命周期 不仅限于半导体产品，从产品开发的角度来看，一款产品通常从"产品企划"开始，经过开发阶段 后进入量产。当量产开始后，会在一定时间内持续生产，随后逐渐缩减产量，最终结束生产。这一 连串的过程被称为"生命周期"。本文将探讨的焦点，是这一生命周期的长度 （周期） 。 仅我是芯片超人花姐，入行20年，有50W+芯片行业粉丝。 有很多不方便公开发公众号的， 关于芯片买 卖、关于资源链接等， 我会分享在朋友圈 。 0 1 半导体产品的生命周期 首先，让我们来思考一下半导体产品的生命周期。一般来说， 普通 半导体产品的生命周期可以如 图1所示。 这里引用一份资料。这份资料是由日本"经济团体联合会" （经团联） 在1998年编制的《强化产业 技术实力现状调查报告》 （産業技術力強化のための実態調査） 。在这份报告中，针对企业加强技术实 力的举措，调查了各个业务领域的 开发周期 与产品生命周期的关系。虽然这份资料距今已有20多 年，但其中反映的趋势至今仍未发生根本性变化，因此我们可以参考其中的一部分数据。 扫码加我本人微信 | | | 開発リードタイム | (年) | | 製品ライフサイクル | (年 ...

Core Viewpoint - Three companies, Mitsui Chemicals, Idemitsu Kosan, and Sumitomo Chemical, have reached a basic agreement to integrate their general resin businesses in Japan, aiming to enhance production and logistics efficiency amid a challenging market environment influenced by excess capacity in China [2][4].
