推动化(hua)(hua)工(gong)(gong)(gong)发(fa)展的(de)(de)(de)动力是(shi)(shi)工(gong)(gong)(gong)农业(ye)生(sheng)(sheng)产和(he)人民生(sheng)(sheng)活对(dui)化(hua)(hua)学(xue)品(pin)的(de)(de)(de)需要，它所(suo)依靠的(de)(de)(de)基(ji)(ji)础是(shi)(shi)化(hua)(hua)学(xue)、 物(wu)理学(xue)、数(shu)学(xue)和(he)各种(zhong)(zhong)工(gong)(gong)(gong)程(cheng)技(ji)(ji)术。其(qi)中(zhong)与化(hua)(hua)学(xue)的(de)(de)(de)关系(xi)(xi)尤(you)为密(mi)切，化(hua)(hua)学(xue)是(shi)(shi)化(hua)(hua)工(gong)(gong)(gong)须臾不(bu)(bu)能离(li)开(kai)的(de)(de)(de)学(xue)科(ke)。在(zai)它们之间，也曾有(you)过(guo)"工(gong)(gong)(gong)业(ye)化(hua)(hua)学(xue)"、"应用化(hua)(hua)学(xue)"等学(xue)科(ke)，起过(guo)一定(ding)的(de)(de)(de)历史作(zuo)用。化(hua)(hua)工(gong)(gong)(gong)基(ji)(ji)本建(jian)设(she)离(li)不(bu)(bu)开(kai)土(tu)木工(gong)(gong)(gong)程(cheng)、电(dian)力工(gong)(gong)(gong)程(cheng)。化(hua)(hua)工(gong)(gong)(gong)机(ji)械(xie)(xie)(xie)的(de)(de)(de)制(zhi)造(zao)离(li)不(bu)(bu)开(kai)机(ji)械(xie)(xie)(xie)工(gong)(gong)(gong)程(cheng)和(he)各种(zhong)(zhong)金(jin)属材料，尤(you)其(qi)是(shi)(shi)不(bu)(bu)锈钢，乃至(zhi)特种(zhong)(zhong)钢材。化(hua)(hua)工(gong)(gong)(gong)机(ji)械(xie)(xie)(xie)特别注意的(de)(de)(de)是(shi)(shi)高温、高压下的(de)(de)(de)可(ke)靠性，即指(zhi)系(xi)(xi)统(tong)、设(she)备、元件在(zai)规定(ding)条件下完(wan)成(cheng)规定(ding)功能的(de)(de)(de)概率。现代(dai)化(hua)(hua)工(gong)(gong)(gong)装置趋于大型化(hua)(hua)、单系(xi)(xi)列生(sheng)(sheng)产，对(dui)于可(ke)靠性的(de)(de)(de)研究(jiu)就显(xian)得格外(wai)重要。微电(dian)子技(ji)(ji)术 电(dian)技(ji)(ji)术都离(li)不(bu)(bu)开(kai)微电(dian)子技(ji)(ji)术。在(zai)微电(dian)子技(ji)(ji)术中(zhong)，大规模和(he)超大规模集成(cheng)电(dian)路的(de)(de)(de)应用，对(dui)化(hua)(hua)工(gong)(gong)(gong)提出(chu)了新的(de)(de)(de)要求。例如超纯(chun)(chun)气(qi)体和(he)纯(chun)(chun)水、电(dian)子工(gong)(gong)(gong)业(ye)用试(shi)剂(ji)、光刻(ke)胶、液晶以及(ji)腐蚀剂(ji)、掺(chan)杂(za)剂(ji)、粘(zhan)合剂(ji)等等。微电(dian)子技(ji)(ji)术中(zhong)使用的(de)(de)(de)超纯(chun)(chun)气(qi)体有(you)几十种(zhong)(zhong)，除氧、氢(qing)、氮、二氧化(hua)(hua)碳、氩等常见气(qi)体外(wai)，还有(you)硼烷、三氯化(hua)(hua)硼、二氯硅烷、四氟化(hua)(hua)碳等自然界(jie)不(bu)(bu)存在(zai)的(de)(de)(de)气(qi)体。所(suo)用化(hua)(hua)工(gong)(gong)(gong)产品(pin)的(de)(de)(de)纯(chun)(chun)度对(dui)半(ban)导(dao)体成(cheng)品(pin)的(de)(de)(de)影响很大。
