MILPITAS, Calif. — May 3, 2021 — World­wi­de sili­con wafer area ship­ments incre­a­sed 4% to 3,337 mil­li­on squa­re inches in the first quar­ter of 2021 com­pa­red to the fourth quar­ter of 2020, top­ping the pre­vious his­to­ri­cal high set in the third quar­ter of 2018, accord­ing to the SEMI Sili­con Manu­fac­tu­rers Group (SMG) in its quar­ter­ly ana­ly­sis of the sili­con wafer indus­try. First-quar­ter 2021 sili­con wafer ship­ments saw 14% growth from the 2,920 mil­li­on squa­re inches log­ged during the same quar­ter last year.


Logic and found­ry con­ti­nue to dri­ve strong demand for sili­con wafers,” said Neil Wea­ver, chair­man SEMI SMG and Vice Pre­si­dent, Pro­duct Deve­lo­p­ment and App­li­ca­ti­ons Engi­nee­ring at Shin Etsu Han­do­tai Ame­ri­ca. “The memo­ry mar­ket reco­very fur­ther bols­te­red ship­ment growth in the first quar­ter of 2021.”

Data cited in this release inclu­des polis­hed sili­con wafers such as vir­gin test and epi­ta­xi­al sili­con wafers, as well as non-polis­hed sili­con wafers ship­ped to end users.

Sili­con wafers are the fun­da­men­tal buil­ding mate­ri­al for the majo­ri­ty of semi­con­duc­tors, which, in turn, are vital com­pon­ents of all elec­tro­nics goods, inclu­ding com­pu­ters, telecom­mu­ni­ca­ti­ons pro­ducts, and con­su­mer elec­tro­nics. The high­ly engi­nee­red thin disks are pro­du­ced in dia­me­ters of up to 12 inches and ser­ve as the sub­stra­te mate­ri­al on which most semi­con­duc­tor devices, or chips, are fabricated.

The SMG is a sub-com­mit­tee of the SEMI Elec­tro­nic Mate­ri­als Group (EMG) and is open to SEMI mem­bers invol­ved in manu­fac­tu­ring poly­crystal­li­ne sili­con, monocrystal­li­ne sili­con or sili­con wafers (e.g., as cut, polis­hed, epi). The pur­po­se of the SMG is to faci­li­ta­te collec­ti­ve efforts on issu­es rela­ted to the sili­con indus­try inclu­ding the deve­lo­p­ment of mar­ket infor­ma­ti­on and sta­tis­tics on the sili­con indus­try and the semi­con­duc­tor market.
