TSMC updates guidance following production hiccup due to bad chemicals

Production at Taiwan Semiconductor Manufacturing Company’s (TSMC) Fab 14B was disrupted last month after a bad batch of chemicals somehow made it into the facility. Now, we have a better idea of the scope of the incident.

TSMC said in a recent press release that the photoresist material in question was abnormally treated, creating a foreign polymer that produced an undesirable effect on 12-nanometer and 16-nanometer wafer production.

As such, TSMC decided to scrap a larger number of wafers than previously estimated, reducing expected first quarter revenue by about $550 million. Gross margin, operating margin and earnings per share outlooks are also taking a hit, to the tune of 2.6 percentage points, 3.2 percentage points and NT $0.42, respectively.

That said, TSMC notes that wafers scrapped in the first quarter will be made up in the second quarter, contributing roughly $550 million to Q2 revenues and increasing gross margin, operating margin and earnings per share by 1.5 percent, 2.1 percent and NT $0.34, respectively.

All said and done, Q1 revenue is now expected to come in between $7 billion and $7.1 billion with a gross profit margin between 41 percent and 43 percent and an operating profit margin of between 29 percent and 31 percent.

For the full year, TSMC believes the fiasco will reduce gross margin by 0.2 percent, operating margin by 0.2 percent and earnings per share by NT $0.08.

I understand the problem well because I have read Conan Doyle book just on this problem. So the story goes some doc or scientist has created a formula that changed his appearance drastically in 18th century. He used it to live a life of vile pleasures and exploring every dark part of his conscience. He has become well known for his ugly behavior as this second person he created and people despised this character while not knowing that this is the same respected neighbor they knew for a long time.
But then when he received a chemical or salt that didnt contain a crucial element that allowed him to get back to his normal appearance it was all gone. Once explored all the darkness and evil he was doomed to lose his respect he has built as a good citizen of that city. This is pretty much what is happening to TSMC.
