Nexperia (formerly NXP, Philips, Mullard) have a semiconductor manufacturing plant (wafer Fab) off Bramhall Moor Lane in Hazel Grove. The site has been there for over 25 years and currently employs around 650 people. Before that, the site was at School Street, which has an interesting history. Before 1939, the site beside the Marcliff (later Warwick) cinema at the south end of the village had a garage and petrol station (opposite Jack Sharp's greyhound track), which was converted at the outbreak of war into an aircraft factory, occupying the entire triangle between Macclesfield Road and the two railway lines. This seemed also to have been extended behind the Norbury Church, in School Street. At the end of the war, prefabs were built. The Macclesfield Road site was taken over later for pharmaceuticals by British Schering. Eventually, G.E.C. started a transistor factory at the School St address. Both of these locations are now light industrial estates housing a number of small businesses, some still in the original buildings.
