Plume behavior and thin film deposition by laser ablation using a hellicoidal shadow mask
SPIE Proceedings, 2000The laser ablation is one of the best ways to obtain smooth thin film deposited on various substrates. However, to obtain a `droplets-free surface some special experimental setups are necessary. One of them is the 'eclipse' method, using a plane shadow mask.

Precise three-dimensional control of micro-optical elements has recently been achieved using shadow masked metalorganic chemical vapor deposition (MOCVD) with an epitaxial mask. However, the epitaxial shadow mask used to deposit these precision micro-optics limits the size and shape of the available structures.

Thin Silicon Shadow Masks for Organic Light-Emitting Diodes (OLED) Deposition Processes
, 2007 本篇論文探討矽材料熱蒸鍍遮罩在真空熱蒸鍍製程中使用的特性，並可在有機發光二極體顯示器製造過程中使用。 有機發光二極體顯示器具有低耗電、廣視角以及製造流程簡單的特性，而在世界各地引起廣泛的研究。因為其材料特性，使得我們無法使用傳統半導體顯影製程去進行圖形化製造，而必須在真空蒸鍍中使用熱蒸鍍遮罩去定義圖形。傳統的熱蒸鍍遮罩的材料為金屬，但其在連續使用後的清洗過程中易遭受酸性溶液的腐蝕。再者，一般金屬具有較大的熱膨脹係數以及較低的楊氏係數 ...

Abstract Thin film Mo–Se–Ni–C coatings for tribologycal applications were prepared by pulsed laser co-deposition from two targets — MoSe 2 (Ni) and graphite. Two methods of deposition from the MoSe 2 (Ni) target were used: deposition with unhindered expansion of the laser plume (standard PLD) and deposition of a plume scattered in collisions with Ar ...

We demonstrate improved emission from LEDs and resonant-cavity LEDs (RC-LEDs) via shadow mask deposited nonplanar dielectric layers. We review the shadow mask deposition method, and present detailed studies comparing devices with and without such ...

Plume propagation and Pt film growth during shadow-masked pulsed laser deposition in a buffer Ar gas
Nuclear Instruments and Methods in Physics Research Section B: Beam Interactions with Materials and Atoms, 2015Abstract Shadow-masked pulsed laser deposition (SMPLD) enables the preparation of films that contain none of the droplets that are normally formed in laser irradiation of the target. The platinum (Pt) film produced by SMPLD was studied using scanning electron microscopy (SEM), atomic force microscopy (AFM), and Rutherford backscattering spectroscopy (

The deposition of uniform thin films is a critical process requirement in manufacturing precision optical components. Nonuniform thicknesses directly degrade device performance, creating a need for robust process control solutions. This paper presents an adaptive computational framework for the engineering and optimization of shadow masks, designed to ...

High-quality LiNbO3 thin films were grown by pulsed laser deposition (PLD) with a shadow mask. Epitaxial and twin-free films were obtained using a single crystal target without a post-annealing process. The film had a very smooth surface without the particulate problem, which is common in films grown by conventional PLD.
