Description
<実施形態1>
図1は、実施形態1に係るTFTの要部の模式的断面図である。ガラス基板等の絶縁性の基板11の表面にゲート電極12が形成されており、ゲート電極12を覆って基板11上にゲート絶縁膜13が形成されている。ゲート絶縁膜13は、例えば窒化シリコンの層である。ゲート絶縁膜13の表面の内でゲート電極12の上側には、シリコン層14が形成されている。シリコン層14は、非晶質シリコンで構成された非晶質部141と、多結晶シリコンを含んでいる第1多結晶部142と、多結晶シリコンを含んでおり、第1多結晶部142よりも結晶性が低い第2多結晶部143とを含んでいる。ここで、「結晶性が低い」とは、第2多結晶部143では結晶化率(結晶化度)の値が第1多結晶部142よりも小さくなっていることを意味している。
実施形態2においては、シリコン層14内の各部分の配置が異なる形態を示す。図10は、実施形態2に係るTFTの要部の模式的平面図である。TFTの断面構造は実施形態1と同様である。図10には、シリコン層14、ソース電極17及びドレイン電極18の平面視における位置関係を示しており、TFTのその他の構造は省略している。シリコン層14中の二か所に第1多結晶部142が形成されており、二か所の第1多結晶部142は平面視で離隔している。一方の第1多結晶部142は、ソース電極17をシリコン層14に射影した位置の一部を含んでおり、他方の第1多結晶部142は、ドレイン電極18をシリコン層14に射影した位置の一部を含んでいる。
