Whereas an increase in brightness and efficiency is mostly a question of the LED chip design, a reduction of the costs is in the focus of the manufacturing technology. As Haitz stated in 2000, the cost per lumen falls by a factor of 10 every decade. This, later referred to as Haitz\u2019s law [1] , is considered the LED counterpart to Moore\u2018s law, which states that the number of transistors in a given integrated circuit (IC) doubles every 18 to 24 months. Both laws rely on the process optimization in the production of semi &#8211; conductor devices. However, at the IC industry it is recognized that an increase in the number of transistors come along with higher costs as manufacturing processes then have to meet higher requirements. These performance related\u00a0 expenses need to be compensated to keep the\u00a0 overall costs low. Several factors could be key to\u00a0 success, e.g. the introduction of standards, the\u00a0 integration\u00a0 of\u00a0 several\u00a0 functions\u00a0 to\u00a0 minimize\u00a0 the\u00a0\u00a0 number of process steps or the increase of the\u00a0 wafer size from &gt;2&#8243; to 300 mm or even 450 mm\u00a0 in the near future.<\/p>\n<\/div>\n<div class=\"separator-brick brick\">\n<div class=\"row\"><\/div>\n<\/div>\n","protected":false},"excerpt":{"rendered":"<p>Since LED became an attractive alternative for general lighting, the market demand for higher brightness, higher efficiency and lower costs was the motivation for improving the LED tech &#8211; nology.
